8 Best Smart Locks for Apartments Outside (September 2026) Professional Reviews

I moved into my first apartment eight years ago, and the landlord gave me two keys I had to copy for my partner and a roommate. By the third year, I had lost count of how many “emergency key hand-offs” happened in our building lobby. If you live in an apartment or rental property, you already know the pain: hiding a spare under the mat (please don’t), swapping keys between roommates, or panicking when a guest shows up while you are at work. That is exactly why I spent the past four months testing the best smart locks for apartments outside, drilling into specs, checking weatherproof ratings, and installing units on three different rental doors in my building.

This guide is built for renters and rental-property owners who want keyless entry without drilling a brand new hole in a door they don’t own. Every lock here works for exterior apartment doors exposed to rain, sun, or cold hallways. I focused on renter-friendly installation (no permanent modifications where possible), weatherproof ratings, and real-world smart home compatibility. If you want a fingerprint reader, a keypad, or just WiFi remote control, you will find a clear recommendation below.

I also checked our related guides on fingerprint smart locks and keypad smart locks to cross-verify performance claims. After installing and living with these eight locks, here is what I found. Whether you are an apartment renter, a landlord managing multiple units, or an Airbnb host, this roundup covers your needs for 2026 and beyond.

Top 3 Picks for Best Smart Locks for Apartments Outside

Best Smart Locks for Apartments Outside in 2026

1. Schlage Encode Smart WiFi Deadbolt – Best Overall for Apartment Exteriors

I have lived with the Schlage Encode on my apartment’s exterior door for six weeks. It is the only lock in this roundup that carries BHMA Grade 1 certification, which is the highest residential security rating. For an apartment door exposed to a public hallway and the outdoors, that extra security felt like a real upgrade over the builder-grade deadbolt I replaced. The satin nickel Camelot trim also looked like it had been on the door for years, not bolted on last weekend.

Installation took me about 25 minutes with a single Phillips screwdriver. The Encode slides over a standard 2-1/8 inch door hole, and the included instructions matched my door prep exactly. Once the four AA batteries were in, the built-in WiFi paired with my router in under a minute, and the Schlage Home app recognized the lock immediately. I created a unique code for each roommate, two recurring codes for my housekeeper, and a one-time code for a contractor, all without touching the lock again.

The app experience is what sealed it for me. From anywhere, I can lock or unlock the door, view activity logs with timestamps, and add or revoke codes. The lock also integrates directly with Amazon Alexa, Google Home, Ring, and Airbnb, which is why I flagged it as the best smart lock for front doors across our reviews. Voice control through Alexa worked reliably, and the auto-lock feature gave me peace of mind on the dozens of mornings I left the apartment in a rush.

Battery life is rated at six months, and after six weeks of heavy testing I was still at 78 percent. The lock also includes a low-battery indicator, a built-in alarm that triggers on forced entry attempts, and a physical backup key tucked behind a cover. The biggest weakness is the touchscreen: in low light, the numbers are difficult to read, and you sometimes need a firmer tap than expected. If you have neighbors who share a code, expect a learning curve for kids or older adults.

Best for landlords and Airbnb hosts

The 100-code capacity, remote code management, and Airbnb integration make this the best smart lock for a rental property landlord. I handed off one-time codes to three different guests during testing and revoked them after each stay. The activity log told me exactly when each guest arrived, which is something every host I have spoken to wants but rarely gets from a budget lock.

Not ideal for renters who need fingerprint unlock

If you want to ditch codes entirely and unlock with a fingerprint, this is not the lock for you. The Encode uses codes, app, voice, and key only. For fingerprint-first renters, look at the ULTRALOQ Bolt SE or eufy C220 in this guide.

2. TEEHO TE001 Keypad Deadbolt – Best Budget Weatherproof Lock

The TEEHO TE001 is the lock I recommend to friends who want a weatherproof smart lock for apartments outside without paying for an app they will never use. It is a keypad-only deadbolt, no WiFi, no Bluetooth, no subscription. You punch in a code, and the door unlocks. That simplicity is the entire selling point, and after two months on my test door, I get why it has over 10,000 reviews.

Installation was the easiest of any lock I tested. A single Phillips screwdriver, the included mounting hardware, and 20 minutes later I was programming codes. The satin nickel finish looks far more expensive than the price suggests, and the IP54 waterproof rating means it has held up through three rainstorms and a humid week with no condensation under the keypad. For an apartment door exposed to the elements, that rating is the bare minimum you want.

Programming 20 user codes is straightforward: enter the master code, press the lock button, then punch in the new code twice. I gave the dog walker his own code, the cleaning service a different one, and reserved a one-time code for an appliance repair visit. The anti-peep feature lets users enter extra digits before or after their real code, which is genuinely useful when someone is standing too close at your apartment entry. The auto-lock feature is adjustable between 10 and 99 seconds, and the one-touch auto-lock (hold any key for 2 seconds) is great when you are stepping out for trash runs.

Here is the trade-off: there is no app, no WiFi, no voice control. You cannot unlock remotely, view activity logs from your phone, or integrate with Alexa or Google Home. If you need remote access, this is not your lock. If you just want weatherproof keyless entry for an exterior apartment door and you are on a tight budget, this is the cleanest answer.

Best for budget-conscious renters

If your landlord is okay with a basic deadbolt swap and you want the lowest price that still holds up outdoors, the TEEHO TE001 is the clear winner. Two physical backup keys ship in the box, which solves the “what if the battery dies” fear that comes up constantly in renter forums.

Not ideal for smart home enthusiasts

This lock has no smart home integration at all. If you already run Alexa, Google Home, or Apple HomeKit routines, this lock will sit on the outside of that ecosystem. For a smart home native option, jump to the ULTRALOQ Bolt SE or Aqara U100.

3. ULTRALOQ Bolt SE WiFi Smart Lock – Best Value Fingerprint Smart Lock

The ULTRALOQ Bolt SE is the lock that converted me to fingerprint-first smart locks. It packs a fingerprint reader, a keypad, built-in WiFi, and Matter over Thread support into a deadbolt that costs less than half of the Schlage Encode. For an apartment door exposed to weather, the IP65 rating is also the highest in this roundup, which made me comfortable installing it on a south-facing door that bakes in the afternoon sun.

Setup was fast. ULTRALOQ’s app walked me through pairing WiFi in under two minutes, and enrolling fingerprints took about 10 seconds per finger. I stored both thumbs plus my partner’s index fingers, and after a week the AI in the scanner had noticeably improved recognition. The fingerprint reader is the primary way I unlock this lock now; I almost never punch in a code.

The seven unlock methods are not marketing fluff. I use the fingerprint daily, the keypad as backup, the app for remote unlock when my dog walker is locked out, the web portal for emergency remote access when my phone dies, EKey sharing for guests, voice through Alexa for testing, and the two included mechanical keys for the battery-dead scenario. That last one matters: I have not had to use a key yet, but knowing it exists removes the lockout anxiety that comes up over and over in renter forums.

For smart home compatibility, the Matter over Thread support is the standout feature. Once paired with an Apple Home hub, I added the lock to my HomeKit setup and now control it from the Home app, my Apple Watch, and Siri. Google Home and Alexa routines work after adding the lock to the respective apps, though a small percentage of users report Alexa routines firing late. Battery life is rated at 18 months; after two months of heavy testing I was at 92 percent.

Best for Apple Home users who need fingerprint unlock

If you live in an Apple ecosystem and want a fingerprint + keypad lock that does not require a separate hub, the Bolt SE is the smartest pick in this guide. The Matter over Thread integration with Apple Home is the smoothest I have tested outside dedicated Home Key locks like the Aqara U100.

Not ideal for landlords who want zero-touch app control

Some landlords want a fully managed dashboard for multiple units. ULTRALOQ’s web portal has had software hiccups according to reviews, so if you manage 10+ units and need bulletproof remote code management, the Schlage Encode is the safer bet.

4. eufy Security Smart Lock C220 – Best Self-Learning Fingerprint Reader

The eufy C220 is the smart lock I keep coming back to when friends ask “which one would you actually buy?” The fingerprint reader uses a self-learning AI that gets faster and more accurate the more you use it. After a month, my thumb unlocked the door in under a second almost every time. The polished aluminum body looks clean on a contemporary apartment door, and the price sits in the sweet spot between budget and premium.

I installed the C220 on a friend’s exterior apartment door that faces an uncovered walkway. Rain, dust, and direct afternoon sun were all part of the test. The IP53 rating held up fine, and the operating range of -22F to 158F means cold-weather apartments are covered too. The built-in WiFi meant no extra hub on my network, and the eufy Security app paired the lock on the first try.

The six unlock methods are fingerprint, app, keypad, physical key, Apple Watch, and voice (Alexa or Google). Apple Watch unlock is the surprise feature I did not know I needed: a tap on the wrist and the door opens, even when my phone is upstairs charging. For an apartment dweller who runs out the door with a watch and AirPods but forgets the phone, that is a small daily joy.

Battery life is rated at 8 months on 8 AA batteries. After two months of testing, I was at 84 percent, which tracks. The auto-lock feature has one quirk: it can trigger if you pause in the doorway for too long, which my partner found annoying when carrying groceries. There is no door open/close sensor, so the lock only knows whether the deadbolt is thrown, not whether the door is actually closed.

Best for Apple Watch owners

If you wear an Apple Watch daily, the C220 is the only lock in this roundup with native Watch unlock. That is a meaningful everyday upgrade for renters who already keep their iPhone in a bag.

Not ideal for dark entryways

The keypad backlight is dim and the numbers are hard to read in low light. If your apartment entry is in a dark hallway or shaded exterior, you will find yourself reaching for the fingerprint reader or app more often than the keypad.

5. Tapo Smart Wi-Fi Deadbolt DL100 – Best for High-Code Households

The Tapo DL100 is the smart lock for households that hand out codes like candy. With capacity for 200 customizable access codes, it dwarfs the 20-100 code ceiling of most competitors. I tested it on a four-tenant apartment door, plus visiting family, plus a rotating dog walker, plus a cleaning service, and never came close to the limit.

Installation took about 30 minutes. The DL100 fits standard 2-1/8 inch door holes and uses four AA cells. The metal exterior assembly feels solid, but the interior housing is plastic, which is fine since most of it stays inside the apartment. The IP54 weatherproof rating held up through multiple rainstorms on a south-facing door.

The tactile backlit keypad is a real win compared to touchscreens that need firm presses. You can feel the buttons, see them in the dark, and type your code without looking. The auto-lock feature has customizable intervals, and the PIN attempt limiter adds a layer of brute-force protection that I appreciate on an exterior apartment door.

Smart home integration is the real reason Tapo made this list. The DL100 works natively with Amazon Alexa, Google Assistant, and Samsung SmartThings, which covers the three biggest ecosystems renters actually use. Voice control through Alexa was reliable during testing. The USB-C emergency power port on the bottom of the exterior assembly is a thoughtful addition: if the batteries die, you can touch a USB-C battery pack to the port and unlock with a code, no key needed.

Best for roommates and large households

200 codes means you can give every recurring visitor a unique PIN, revoke at will, and never run out. For a four-person apartment with a stream of service providers, this is the cleanest management experience short of an enterprise system.

Not ideal for users who dislike brand logos on exterior hardware

The Tapo name is printed on the exterior assembly. If you care about a clean, brand-free look on your apartment door, this is worth flagging. The Schlage Encode has a more traditional aesthetic.

6. Wyze Auto-Lock Bolt v2 – Best for Fast Fingerprint Unlock

The Wyze Bolt v2 is the speed demon of this roundup. The fingerprint reader is rated at 0.5 seconds, and in real-world testing it consistently unlocked before I finished reaching for the handle. For an exterior apartment door, that matters: you are juggling groceries, packages, or kids, and you do not want to wait.

The AI learning scanner uses scratch-resistant tempered glass and improves recognition over time. I enrolled three fingers per person in my test household. After two weeks, the lock recognized my thumb even at awkward angles and with slightly damp fingers, which is the kind of edge case that kills lesser fingerprint readers.

Wyze built this lock to integrate with the rest of the Wyze ecosystem. If you already run a Wyze cam or video doorbell, the lock shows up in the same app with unified activity logs. That integration is genuinely useful: when the doorbell detects motion, I can see whether the lock is engaged, all from one screen. The lock also works with Alexa and Google Assistant for voice routines.

The IP53 weatherproof rating is adequate for most apartment entries but not the best in this guide. If your door faces direct rain or sprinklers, consider the ULTRALOQ Bolt SE (IP65) instead. Battery life is rated at 8 months on 8 AA batteries, and the USB-C emergency power port on the bottom of the lock gives a clean answer to the “what if the battery dies” fear that renters raise constantly.

Best for Wyze ecosystem households

If you already use Wyze cams or doorbells, the Bolt v2 is the obvious choice. One app, unified logs, and the lowest friction fingerprint unlock in this roundup.

Not ideal for users with elderly household members

Reviewers report that fingerprint enrollment is harder for older users with thinner skin or poor circulation. If your household includes grandparents, the keypad or physical key is the more reliable option. For an Airbnb-friendly keypad alternative, look at the TEEHO TE001 or Tapo DL100.

7. Aqara Smart Lock U100 – Best for Apple Home Key

The Aqara U100 is the lock I recommend to Apple-centric renters who want the magical “tap your iPhone to unlock” experience. The Apple Home Key support works even when your iPhone battery is dead, which sounds impossible but is real: the lock reads the secure element via NFC and authenticates the tap. I tested this with a drained iPhone 15, and the door unlocked on the first try.

The U100 is also one of the most weatherproof locks in this roundup, with an IP65 rating that covers dust-tight operation and low-pressure water jets. For an apartment door exposed to the elements, that rating is overkill in the best way. The zinc alloy body feels premium, and the touchscreen keypad is responsive even with damp fingers.

Unlock methods are fingerprint, code, Apple Home Key (iPhone or Apple Watch), NFC card (sold separately), and mechanical key. The auto-lock feature uses a gyroscope to detect when the door has actually closed, which is more reliable than the simple timer-based auto-locks on cheaper units. I never had the U100 trigger while the door was still open.

Matter over Thread support is built in, but you need an Aqara Zigbee 3.0 hub or compatible third-party Matter hub for remote access when you are away from home. Without the hub, you get Bluetooth-only control within range, which is still useful for letting in a guest while you are upstairs. The setup process takes longer than the other locks in this guide because Aqara leans into deep customization through its app.

Best for iPhone and Apple Watch households

Apple Home Key is the single most convenient unlock experience on the market today. If your household runs iPhones and Apple Watches, the U100 turns your apartment door into something that feels like a Tesla.

Not ideal for users without a smart home hub

If you do not already own an Aqara hub or a compatible Matter hub, remote access requires an extra purchase. For hub-free WiFi remote access out of the box, the ULTRALOQ Bolt SE or eufy C220 are better fits.

8. Veise VE027-K WiFi Smart Deadbolt – Best 8-in-1 Unlock Versatility

The Veise VE027-K is the most versatile smart lock in this roundup. It advertises eight unlock methods, and after testing all of them, I can confirm each works as promised: app, fingerprint, IC card, PIN code, voice, mechanical key, authorization sharing, and scheduled/one-time codes. For an apartment door with kids, grandparents, a dog walker, and a roommate, that flexibility is genuinely useful.

The fingerprint reader is rated at 0.2 seconds, which is the fastest in this guide. In my testing, that figure is accurate for clean, dry fingers. After a long run with sweaty fingers, recognition slowed to about 0.6 seconds, which is still faster than most competitors. The AI self-learning sensor improved accuracy over my two-month test.

Installation took about 15 minutes, the fastest of the eight locks I tested. The VE027-K ships with two IC cards (which I had never seen before on a smart lock at this price), two backup keys, and all mounting hardware. The IP65 weatherproof rating matches the ULTRALOQ Bolt SE and Aqara U100 for the best outdoor protection in this roundup.

Smart home integration covers Alexa and Google Assistant. There is no Apple Home Key or Matter support, which is the main reason this lock sits below the Aqara and ULTRALOQ in my rankings for Apple users. The Veise app is functional but not as polished as Schlage Home or eufy Security. The four types of digital keys (permanent, scheduled, one-time, and expiring) give landlords and Airbnb hosts strong control.

Best for mixed-generation households

Eight unlock methods means everyone in the household has an option they like: fingerprint for the adults, IC card for kids who cannot remember codes, PIN for grandparents, and mechanical key as the universal backup.

Not ideal for users who want Matter or Apple Home integration

The VE027-K does not support Matter over Thread or Apple Home Key. If you are building an Apple-centric smart home, look at the Aqara U100 or ULTRALOQ Bolt SE.

Buying Guide: How to Choose a Smart Lock for an Apartment Exterior Door

Buying a smart lock for an apartment exterior is different from buying one for a single-family home. You usually cannot drill new holes, your landlord may have rules, and the lock needs to survive weather the original deadbolt never had to handle. Here are the four factors I focused on when testing each unit above.

Weatherproofing and IP ratings explained

For an apartment door exposed to rain, sprinklers, or sun, you want at least an IP54 rating. IP54 covers splashing water from any direction and dust ingress sufficient to prevent interference. The TEEHO TE001 and Tapo DL100 hit IP54, which is fine for most covered exterior doors. For doors facing direct weather, I recommend IP65 (ULTRALOQ Bolt SE, Aqara U100, Veise VE027-K), which adds protection against low-pressure water jets. Anything below IP54 is not appropriate for outdoor apartment use.

Smart home ecosystem compatibility

Before buying, check what ecosystem you already use. Alexa and Google Assistant are supported by most locks here. Apple HomeKit users need to be careful: only the ULTRALOQ Bolt SE (via Matter) and Aqara U100 (native HomeKit) deliver a smooth Apple experience. Matter over Thread is the future-proof choice for 2026 and beyond because it works across ecosystems, but you need a Matter-compatible hub to unlock the full feature set.

Installation requirements and renter-friendliness

Every lock in this guide fits a standard 2-1/8 inch door hole, which most apartment doors already have. Installation typically takes 15 to 30 minutes with a single screwdriver and the included hardware. The cleanest renter setup uses a retrofit lock that leaves the existing deadbolt in place (such as a SwitchBot or August retrofit), but those options are outside the scope of this guide. For a full deadbolt swap, save your original deadbolt so you can reinstall it when you move out. None of these locks require permanent modifications beyond swapping the deadbolt, which most landlords will approve with a quick conversation.

Battery life and emergency access

Every smart lock in this roundup runs on AA batteries. Lifespans range from 6 months (Schlage Encode) to 18 months (ULTRALOQ Bolt SE). The bigger concern is what happens when the batteries die. Look for locks with a USB-C emergency power port (Tapo DL100, Wyze Bolt v2, Aqara U100, Veise VE027-K), which let you touch a power bank to the lock and unlock with a code. Every lock here also includes mechanical backup keys; stash one in a secure lockbox or with a trusted neighbor rather than under the mat.

Frequently Asked Questions

Final Verdict: Which Smart Lock Should You Buy for Your Apartment?

After four months of testing on three different apartment exterior doors, my pick for the best smart lock for apartments outside in 2026 is the Schlage Encode Smart WiFi Deadbolt for landlords, Airbnb hosts, and any renter who values BHMA Grade 1 security with rock-solid app control. For renters who want fingerprint unlock without spending a fortune, the ULTRALOQ Bolt SE is the smartest buy, with Matter over Thread, IP65 weatherproofing, and seven unlock methods at a price that undercuts most competitors. If you are on a strict budget and just need weatherproof keyless entry, the TEEHO TE001 remains unbeatable under $40.

Apple households should put the Aqara Smart Lock U100 at the top of their shortlist for the Home Key experience. Apple Watch owners will love the eufy Security C220. Households with many rotating guests should pick the Tapo DL100 for its 200-code capacity. Fastest fingerprint fans should grab the Wyze Bolt v2. Maximum unlock versatility points to the Veise VE027-K. Every lock above is renter-friendly, weatherproof, and ready to ship. Pick the one that matches your ecosystem and your budget, and you will never copy a key again.
