The best smart locks under 200 dollars right now are the TEEHO TE001 for pure keypad value, the ULTRALOQ Bolt SE for homes that run Matter, and the Wyze Palm Lock for contactless entry. My overall pick is the TEEHO TE001: it carries an ANSI Grade 3 rating, holds 20 individual user codes, and has more than 10,000 owner reviews behind it. No hub, no app, no subscription, no cloud account.
I spent the last few weeks reading every specification sheet, owner review theme, and warranty line across eight locks in this price band, then cross-checked them against what people actually report in the r/AugustSmartLock and r/smarthome threads. This is a research-based guide, not a hands-on test, and I say so up front because the alternative is pretending to measurements I never took.
One warning before the list. Several fingerprint and keypad locks in this price range ship without any way to reach them from outside your home. Buying a Bluetooth lock, then discovering away-from-home access needs a separate gateway, is the single most common way people blow past their own budget. Every pick below tells you plainly whether a hub is required.
If you also want the wider picture, our general smart lock guide covers locks at every price tier, and our keypad lock roundup goes deeper on PIN-only models.

1. TEEHO TE001 Keypad Deadbolt: The Best Smart Lock Under 200 Dollars Overall
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Satin Nickel
ANSI Grade 3
20 user codes
4 AA batteries
2 backup keys
No app or hub
- Largest review base in the group
- Installs in an existing bore with a screwdriver
- 20 individual codes plus one-time guest PINs
- Two physical backup keys included
- No WiFi
- app or voice assistant connectivity
- Fits only 2-1/8 inch (54mm) bores
- Exterior housing feels lightweight
I keep coming back to this lock because it does one job with no hidden dependencies. There is no account to create, no firmware to update, and nothing that stops working when a company changes its cloud. You type a code, the bolt retracts. That simplicity is worth a lot when your door is the only thing between your family and the street.
The keypad holds 20 individual user codes plus one-time guest PINs that erase themselves after use, which makes it a reasonable fit for a short-term rental. The anti-peeping feature lets you enter extra digits before or after your real code so someone watching over your shoulder sees a longer string than the one that opens the door. Auto-lock timing is adjustable from 10 to 99 seconds, and a one-touch lock means you do not have to re-enter anything on the way out.
Owners consistently point to installation as the surprise: most replace an existing deadbolt in the same hole with a screwdriver and are done. The body auto-detects the door hand on power-up, so there is no manual handedness toggle. Battery life is quoted at up to 365 days on four AA cells, and a low battery indicator lights up before you get locked out. Note that batteries are not included in the box.
The honest limitation is that this is not a connected lock at all. If your household wants to unlock the door from the driveway, check arrival codes from work, or see a log of entries, this is the wrong pick. It also only fits the 2-1/8 inch (54mm) standard bore, not the wider 38mm holes used on some metal doors, and the exterior housing reads as lighter in the hand than the Grade 3 badge suggests.
Who the TEEHO TE001 suits best
It suits households that want codes instead of keys and nothing more: a family of four needing one code each, a home office with shared entry, or a garage-side door. Two spare keys are included, so anyone who prefers a physical key still has one, which makes handing a key to a neighbour a non-event. For short-term lets, the one-time PINs mean you can issue a code per guest and skip the key handoff entirely.
It also suits anyone in a rental where an exterior hardware change is not permitted, provided your landlord allows an interior-only keypad swap. The deadbolt body stays the same from the outside, so the door still looks untouched from the street.
Where the TEEHO TE001 falls short
It cannot tell you the door is ajar, cannot auto-unlock as you approach, and cannot be shared remotely. If your household is already running smart home routines, a lock with no network radio cannot join them at all.
The 10 to 99 second auto-lock window is coarse. On a busy door that gets bumped by wind or a shoulder, a short delay can leave the bolt chasing the strike plate. The lock does not fully retract the latch in a misaligned frame, which owners sometimes mistake for a defective unit when the auto-lock struggles.
Those are minor, but worth knowing before you buy for a main entrance in a high-traffic house.

2. ULTRALOQ Bolt SE: Best Value Fingerprint Lock With Matter Support
ULTRALOQ Bolt SE Wi-Fi Smart Lock, Matter Over Thread, App Remote Access
Fingerprint and keypad
Built-in 2.4 GHz WiFi
Matter over Thread
Up to 18 months battery
- Built-in WiFi means no hub for the WiFi path
- Seven entry methods including eKey sharing
- Stores 50 fingerprints and 50 codes
- Lifetime mechanical warranty with 18-month electronics
- Matter features need a Thread Border Router
- 2.4 GHz only and best within about 70 feet of the router
- No door ajar sensor included
This is the pick for anyone whose smart home has moved past brand-locked ecosystems. It speaks WiFi for everyday remote control and Matter over Thread for the newer Apple Home, Alexa, Google Assistant, and SmartThings path. You get fingerprint, passcode, app, web portal, eKey sharing, voice, and mechanical key on one unit.
Storage is generous for the money: up to 50 fingerprints and 50 access codes, with permanent, scheduled, and temporary eKeys that carry an access history. Battery life is listed at up to 18 months because the Thread radio draws so little, which is the strongest endurance claim in this group.
Install is roughly a ten-minute swap for an existing deadbolt, and the body is a BHMA-certified zinc alloy rated IP65 for exposed doors. Owners frequently mention that the self-healing Thread mesh reroutes around a device that drops offline, which is a genuine advantage in a house with dead WiFi spots.
The caveat that trips people up is that full Matter functionality still needs a Thread Border Router in the home, separate from the router that handles the lock’s own WiFi path. And the built-in WiFi is 2.4 GHz only and performs best within roughly 70 feet of your router, so a deadbolt on the far side of a large house can be flaky. A small share of reviews, around 9%, are one-star, mostly around connectivity and fingerprint consistency.
What the Bolt SE gets right for Matter homes
Matter support is the differentiator. If you run Apple Home, Alexa, Google Assistant, or SmartThings and want to avoid rekeying every lock when you change platform, this one travels. The web portal is also useful if you manage more than one property from a laptop.
The warranty is the strongest split in the roundup: lifetime mechanical coverage alongside 18 months of electronics. That is the number most budget brands leave vague.
Where the Bolt SE gets frustrating
There is no door ajar sensor, so you get a lock state but not an open-door alert, and no auto-unlock geofencing to record. If your main worry is knowing the door is still open when you are halfway down the street, look elsewhere.
The 2.4 GHz range limit is the practical trap. Measure before you commit, and be ready to add a mesh node if the lock sits far from your main access point.

3. Sifely Smart Lock: Best for Short-Term Rentals and Guest Access
Fingerprint Smart Door Lock with Handle & Keypad – No More Lost Keys, Keyless Entry & Remote Access for Home, Kids, Airbnb & Rental Property, DIY Install, Alexa & Google Compatible
Fingerprint,passcode,app,fob and key
Bluetooth with optional gateway
Reversible handle
One-year warranty
- Five redundant entry methods for a rental door
- Reversible handle fits most doors without drilling
- Guest PINs and access logs in the app
- Customers praise Sifely for replacing faulty units
- Remote access and voice control need the sold-separately Sifely WiFi Gateway
- Touchscreen sometimes needs multiple taps to wake
- Cannot be rekeyed to a common key system
The Sifely is a lock with a handle rather than a bare deadbolt, so it gives you five ways in: fingerprint, keypad passcode, Bluetooth app, an RFID key card fob, and a physical key. That redundancy is what makes it a good rental pick, because a guest fob or a one-time PIN never depends on a phone being charged.
For Airbnb-style stays, the Bluetooth app generates temporary guest PINs and keeps an access record. Two keys and two key cards ship in the box. The reversible handle works on either door hand, and most owners report fitting an existing handle, knob, or deadbolt with no extra drilling.
Battery swaps do not require removing any screws, which matters when you are changing cells between guests. There is also an interior privacy button that disables all electronic entry while still allowing the physical key.
Two limitations shape the ownership experience. Remote unlock, access history, and Alexa or Google control all require the Sifely Wi-Fi Gateway, which sells separately and can move the true cost above your cap. And the cylinder cannot be rekeyed to a common key system, so the supplied keys are the only keys.
Why hosts and families like the Sifely
Support is repeatedly called out in reviews, with several owners describing replacement of faulty units. One reviewer reported four years of service before needing a new lock, which is a longer field history than most fingerprint models in this price band.
The key card fob is the underrated part. For an elderly parent, a housecleaner, or a child, handing over a card beats sharing a PIN that gets written on a sticky note.
Where the Sifely will disappoint you
The touchscreen keypad can be slow to wake and sometimes needs multiple taps, and some users report the fingerprint reader forgetting prints after a short period. There is no lockout after repeated wrong codes, only an attempt log.
Water sealing is the real caution on an exposed door. A small number of reviews describe water intrusion, and owners recommend a cover or sealant. One further edge case: raising the interior handle can block electronic unlocking completely, leaving only the physical key.

4. eufy Security Smart Lock C220: Best for Apple Watch and eufy Homes
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
Six unlock methods
Built-in WiFi
8 AA batteries
BHMA Grade 3, IP53
- Built-in WiFi removes the need for a bridge
- Apple Watch and voice assistant unlock paths
- Self-learning AI fingerprint improves over time
- Installs in about 15 minutes in an existing bore
- About 8 months of battery life is shorter than Thread options
- Keyed different cylinder so keys are not interchangeable
- Fingerprint reader sometimes needs a second touch
The C220 is the cleanest hub-free answer in the roundup for eufy owners, because built-in WiFi means no bridge sits on your network. It offers six unlock paths: fingerprint, app, keypad, physical key, Apple Watch, and voice assistant. The Apple Watch path is the one no other lock in this set matches.
The fingerprint module uses self-learning AI that adjusts recognition as it goes, and it fits standard deadbolts and bores under 54mm without drilling in roughly fifteen minutes. It is BHMA Grade 3 certified after more than 100,000 lock cycles, IP53 rated, and specified to operate from -30C to 70C.
Owners consistently name the built-in Wi-Fi as the deciding factor, along with fast fingerprint reads. Real-time notifications and routines run inside the eufy Security app, so it pairs naturally with eufy doorbells.
What works well on the C220
The hub-free WiFi is the whole pitch. If you already own eufy cameras or a doorbell, this lock shares one app with real-time alerts and no extra bridge to configure.
Apple Watch unlock is genuinely useful for anyone carrying a bag, and it removes the phone from the entry sequence entirely. Eight AA batteries are included in the box, which is uncommon at this price.
Where the C220 costs you
Battery life of roughly eight months is the shortest window among the connected locks here, and owners with heavy door traffic replace cells sooner. Reviewers also report the fingerprint reader occasionally needing a second touch before it registers.
The keyed different cylinder means the supplied keys will not open another lock in your house, so plan for that if you are matching hardware. It is also a lock first and a smart lock second: no Matter, no Thread, no Z-Wave.

5. Yamiry Fingerprint Lock: Best Budget Pick With Six Entry Methods
Smart Door Handle Lock with Keypad, Yamiry Fingerprint Knob for Front Door
Fingerprint,app,passcode,fob,key and voice
Stainless steel and zinc
Bluetooth with optional gateway
No-drill install
- Six unlock methods in an inexpensive package
- About a 10-minute no-drill installation
- App manages multiple locks for landlords
- Reversible handle for both door hands
- Alexa and remote control need the separately sold Wi-Fi gateway
- Bluetooth-only range limits in-person app access
- Fingerprint and connectivity consistency varies between units
The Yamiry packs the most entry paths into the least expensive connected lock here. Fingerprint, Bluetooth app, passcode, key fob, mechanical key, and Alexa voice are all supported, and the app issues permanent or temporary passcodes plus an unlock record history.
Its strongest argument is a roughly ten-minute installation that replaces an existing handle, knob, or deadbolt without drilling, with a reversible handle for either door hand. That combination makes it a candidate for rental doors where exterior changes are not permitted.
One app handles multiple locks, which is the feature landlords and short-term hosts care about most. Passage mode lets you leave the door unlocked during the day without rearming the lock.
The gateway question is the catch. Alexa voice and true remote control require a Wi-Fi gateway sold separately, so the effective cost of remote access lands higher than the lock alone. Within Bluetooth range the app works, but reviewers note the range is limited in practice.
Where the Yamiry earns its place
It sits at a strong position in the Deadbolts category, which suggests broad market validation rather than a niche experiment. For the money, six entry methods and multi-lock app management are hard to match.
Fingerprint and keypad entry are generally reported as fast once set up, and the stainless steel and zinc construction gives it a solid feel that undercuts its price tier.
Where it falls down
Fingerprint performance and Bluetooth connectivity are inconsistent across units, with some owners reporting misses that a second tap fixes. That is a reliability spread rather than a design flaw, but on a primary front door it matters.
There is also no door sensor and no warranty detail published in the listing, which leaves the electronics coverage unclear if a unit fails at month eleven.

6. Veise VE06-H: Best Full Handleset Upgrade in a Single Box
Veise VE06-H Smart Front Door Lock Handle Set, App Control, Matte Black
Full handleset with lever
250+ user codes
App and web portal management
IP55, ANSI Grade 3
- Complete front door upgrade in one product
- Supports one-time
- permanent
- scheduled and recurring codes
- Web portal handles multiple properties
- Two backup keys and two fobs included
- Alexa and Google need the separately sold Veise G2 gateway
- Code programming has a learning curve
- Needs three pre-drilled holes at specific spacing
The Veise is not a retrofit deadbolt, it is a full handleset with an exterior assembly, interior lever, keypad, and smart module in one box. If you are replacing a dated front door set anyway, this consolidates the job and removes the mismatch between an old lever and a new lock.
Its code capacity is the standout: more than 250 users with one-time, permanent, scheduled, and recurring access options. Alongside the mobile app there is a web portal, which is what landlords actually want when managing several doors. Five entry methods are supported: app, code, IC fobs, mechanical key, and thumb turn.
Security settings include auto-lock, one-touch locking, privacy mode, passage mode, and an anti-peeping keypad. It is IP55 waterproof and ANSI Grade 3 rated, and it fits standard doors between 1-3/8 and 2 inches thick in either hand. Warranty is one year limited, extendable by a free extra year with registration, with lifetime phone support.
The catch is physical. It requires three pre-drilled door holes at a specific spacing, so check your door before buying. Alexa and Google Home also need the Veise G2 gateway, sold separately.
What the Veise handles well
The recurring user limit is what removes real friction. Families, cleaning companies, and small landlords can each have their own code instead of sharing one PIN and losing track of who used it.
Support is a genuine strength here. Owners describe Veise as fast, patient, and knowledgeable, and several buyers specifically called support after struggling with initial code programming.
Where the Veise is the wrong tool
Code programming has a real learning curve, and that is where most setup calls come from. Plan thirty minutes for configuration rather than assuming a ten-minute install.
One review reported the lock going offline about two weeks after setup, and another noted minor paint chipping on the inside handle. Both are isolated reports rather than patterns, but on a door you touch every day the finish is worth inspecting early.

7. Wyze Palm Lock: Best Contactless Entry With a Dual Battery System
Wyze Palm Lock, Smart Door Lock with Palm Vein Recognition, Keyless Entry Smart Locks for Front Door, Keypad, Auto Lock, Dual Battery, Wi-Fi, Works with Alexa & Google, BHMA, IP53, Mechanical Key
Palm vein recognition
Dual battery with USB-C emergency charge
Built-in WiFi
BHMA Grade 3, IP53
- Contactless palm vein reading with no finger sensor touch
- Gyroscope auto-lock that waits for the door to close
- Millimeter wave radar battery saver
- Up to 50 unique or one-time guest codes
- Palm enrollment is a learning curve versus fingerprint
- Keypad entry still required as a fallback
- Heavier and bulkier exterior than a standard deadbolt
The Wyze Palm Lock reads the veins in your palm instead of your fingertip, which means you hold your hand up instead of pressing a wet or dirty sensor. That is the whole concept, and owners pick up on it quickly. It also carries the highest average rating of any lock we reviewed.
The battery system is the standout safety feature. A dual design runs a main pack rated about six months, backed by a secondary cell that carries roughly two more weeks, plus USB-C emergency charging. For a lock, that redundancy is more valuable than a longer headline number.
A gyroscope senses the door angle, so auto-lock only engages after the door has actually closed, which removes the false jams that plague cheaper bolt sensors. A millimeter wave radar wakes the lock only when someone is standing there, cutting idle drain. Built-in Wi-Fi means no hub, and it works with Alexa, Google Assistant, and the Wyze Video Doorbell.
There is also a tamper alarm, a door-ajar chirp, and mechanical key backup. Guest codes number up to 50 unique or one-time entries with anti-peep digit padding.
Why the palm reader is worth learning
It suits households where hands are frequently wet, greasy, or gloved, and anyone who does not want to share a fingerprint reader across a family. Enrolling multiple palms is straightforward once you understand the hold position, which the app walks you through.
The radar battery saver and closed-door gyroscope together address the two complaints that surface most often on cheaper smart locks: idle battery drain and auto-lock fighting a door that has not shut.
Where the Wyze Palm Lock is not ready
It is a newer product with a much smaller review base than the long-running keypad and fingerprint models here, so long-term field history is limited. Palm enrollment takes more practice than registering a fingertip.
The keypad and manual code entry must stay configured as a fallback, and the exterior is heavier and bulkier than a standard deadbolt. If your door has a tight reveal, check the interior clearance before you commit.

8. LOCKSTAR Smart Door Lock: Best One-Box Setup With the Gateway Included
LOCKSTAR® Smart Door Lock • Keyless Entry Deadbolt Door Lock • Multiple Entry Methods – APP • Fingerprint Touch ID • Keypad Code • Card FOB • Traditional Key • Smart Home Devices
Five entry methods
WiFi gateway included in the box
Real-time notifications and event history
16 ounces
- Gateway ships in the box
- so remote app access works immediately
- Five entry methods with fingerprint touch ID
- Event history records who opened the lock and when
- Screwdriver and drill bit included
- Higher cost relative to the feature set
- Installation may require drilling without an existing lock hole
- Less market validation than the established brands
The reason to look at the LOCKSTAR is simple arithmetic. Most fingerprint locks in this bracket quote a price and then require a separate gateway for remote access, which quietly breaks a tight budget. This one ships the Wi-Fi gateway in the box.
Entry methods number five: fingerprint touch ID, keypad code, card fob, app, and traditional key. The app provides real-time notifications and a complete event history of unlocks, which is the feature short-term hosts and property managers actually buy for.
Auto-lock triggers on door close, or you can lock manually by long-pressing the number key. The install kit includes a screwdriver and a drill bit, and the manufacturer states it works on virtually any standard door. A private landlord running several doors gets one box and one app instead of two purchases.
Why the bundled gateway changes the maths
Owners single out the included gateway as the reason to buy over similarly priced rivals, because remote control and event history work from the first day with nothing else to buy. That removes the most common reason a fixed budget plan fails.
The five-method setup also means nobody in the household is locked out over a dead battery, a forgotten code, or a dropped phone.
Where the LOCKSTAR gives ground
It is the heavier spend in this roundup for the feature set, and its Deadbolts sales rank sits far below the established brands, which means less long-term field history. That is a real consideration on a primary entrance.
If your door has no existing lock hole, installation needs the supplied drill bit, which pushes a Saturday morning project rather than a ten-minute swap.

How to Choose a Smart Lock Under 200 Dollars
Price is the filter this article starts from, but it is the least useful decision variable. Connectivity, fit, and power decide whether a lock works for you at all. Work through these in order.
Hub or no hub: what connectivity actually costs
A Bluetooth-only lock is not a smart home device, it is a phone with a keypad. Bluetooth range covers you standing at your own door; it does not cover unlocking from work. Away-from-home access on those locks needs a gateway, and gateways are the single most common reason a tight lock budget becomes a larger one.
Four picks here connect straight to WiFi with nothing extra: the ULTRALOQ Bolt SE, the eufy C220, the Wyze Palm Lock, and the LOCKSTAR, whose gateway is in the box. Four need more thought: the Sifely, the Yamiry, and the Veise all want a separately sold gateway for voice or remote control, and the TEEHO has no connectivity at all.
One more nuance. WiFi here means 2.4 GHz, not 5 GHz. A door at the far end of a large house can be unreliable without a mesh node.
Measure your door before you buy
Three measurements decide whether any lock fits. First, the backset, the distance from the door edge to the centre of the bore, which comes in 2-3/8 inch and 2-3/4 inch versions. Second, the cross bore, the diameter of the hole through the door, standard at 2-1/8 inch, which is 54mm. Third, door thickness, which typically runs from 1-3/8 to 1-3/4 inch.
The TEEHO TE001 fits only the 2-1/8 inch bore and will not accept the wider 38mm hole found on some metal doors. The Veise VE06-H needs three pre-drilled holes at a specific spacing rather than a single standard bore. The eufy fits standard bores under 54mm once the spacer is removed.
Measure before you order, not after. Also check that the interior housing clears the door frame when the door is open, especially on locks with a bulky interior module.
Battery life: what to expect after twelve months
Published figures assume a door opened a handful of times a day. Real-world reports are shorter, and owners on r/smarthome describe locks dying sooner than the headline number whenever the radio is on constantly.
Expect roughly six to twelve months on four AA cells for a keypad-only model, and closer to three to six months on a WiFi lock with an always-connected radio. The TEEHO claims up to 365 days on four AA. The ULTRALOQ claims up to 18 months on Thread because that radio draws so little. The eufy specifies about eight months on eight AA. The Wyze Palm Lock uses a dual system: a main pack rated about six months plus a secondary cell for roughly two more weeks.
Four things stretch battery life: use fresh alkaline AA rather than rechargeable cells, which owners repeatedly report as the single biggest cause of short battery life; shorten your PIN; turn off activity logging; and disable geofenced auto-unlock if you do not use it.
When not to buy a smart lock
Skip the category entirely in a few situations. If your door has a double-cylinder deadbolt, which needs a key to get in from outside, a smart lock replaces only part of the security picture and leaves the weak point untouched. If a landlord or HOA controls exterior modifications, an interior-only retrofit such as the Sifely or the Yamiry may be your only legal option, and a full handleset like the Veise may not be permitted.
Mortise locks and multipoint patio hardware are different mechanisms that these retrofit deadbolts do not fit. If you need professional monitoring with a call centre, a smart lock is an accessory to that system, not a replacement for it.
There is also an honest reliability argument. A mechanical deadbolt is simpler, costs far less over five years, and never needs batteries. If you want remote visibility and guest codes, a smart lock earns its place. If you only want to stop carrying keys, a keypad lock like the TEEHO delivers that without the electronics.
If fingerprint deadbolts are what you are after, our fingerprint door lock guide covers the category in more detail.
Frequently Asked Questions
Do I need a hub for a smart lock?
Only if the lock connects over Bluetooth or Thread alone. A Bluetooth lock needs a gateway for away-from-home unlocking, and Matter over Thread needs a Thread Border Router. Built-in WiFi models such as the ULTRALOQ Bolt SE, eufy C220, and Wyze Palm Lock work with no extra hardware. The LOCKSTAR bundles its WiFi gateway in the box.
How long do smart lock batteries last?
Budget for six to twelve months on a keypad-only lock using four AA cells, and three to six months on a WiFi lock with an always-on radio. Published claims run higher: 365 days for the TEEHO TE001, 18 months for the ULTRALOQ Bolt SE on Thread, about 8 months for the eufy C220 on eight AA. Heavy door traffic shortens all of these.
What happens if the batteries die?
Every lock here keeps a physical key fallback, which is why we favour models with a keyway. The ULTRALOQ and eufy include two emergency keys, and the Wyze Palm Lock adds a secondary battery plus USB-C emergency charging. Keypad-only locks like the TEEHO include two backup keys and a low battery indicator that lights up before failure.
Are smart locks under 200 dollars secure?
Security at this price is mostly a grade question. Every lock in this roundup is ANSI or BHMA Grade 3, the lowest common grade. Treat the grade as the floor, then harden the door: use 3 inch screws into the strike plate stud, reinforce the strike plate with a longer one, and confirm the bolt fully extends into a properly aligned frame. Most break-ins fail on frame and hardware, not the lock body.
Can I install a smart lock myself?
Usually yes. Most of these replace an existing deadbolt in the same 2-1/8 inch bore with a screwdriver and take ten to fifteen minutes. The exception is the Veise VE06-H, which needs three pre-drilled holes at a specific spacing. The ULTRALOQ Bolt SE auto-detects the door hand on power-up, so check handedness only if the bolt does not retract smoothly.
Do smart locks work with Alexa or Google Home?
It depends on connectivity, not brand. The ULTRALOQ Bolt SE reaches Alexa and Google directly over WiFi and Matter. The eufy C220 and Wyze Palm Lock support voice assistants over built-in WiFi. The Sifely, Yamiry, and Veise all need a separately sold gateway for voice control, which is the cost most buyers forget to count.
The Bottom Line
The best smart locks under 200 dollars are not decided by features, they are decided by connectivity. The TEEHO TE001 takes the overall spot because it delivers 20 codes, Grade 3 security, and a two-year warranty with zero extra hardware to buy. If you need remote access from a Matter home, take the ULTRALOQ Bolt SE. If you want no finger touching the sensor, take the Wyze Palm Lock.
Measure your bore before ordering, count the gateway in your budget, and fit 3 inch screws into the strike plate while you are in there. The lock is only one part of the door.
