Best Smart Locks With Key (2026)

Fingerprint Scan with Six Unlock Methods

Coming home with your hands full, the fingerprint smart lock reads your thumb before you reach the door. We tested the fingerprint alongside the keypad, app, and mechanical key backup over several weeks. The fingerprint worked reliably on our test door, though wet or muddy fingers occasionally needed a second try. The real advantage here is redundancy: if your phone dies or you forget the code, you still have five other ways in.

Keypad Entry with Custom PIN Codes

The keypad smart lock lets you set multiple PIN codes for family members and generate one-time codes for contractors or Airbnb guests directly from the app. We installed this on our existing deadbolt without removing it, and the keypad sat flush with the door. One quirk we noticed: the keypad can be slow to respond if the battery is running low, so don't wait until the last warning to swap batteries.

DIY Installation Without Drilling

The handle replaces your existing knob or deadbolt in about 10 minutes using just a screwdriver. We tested the fit on standard American doors and had no compatibility issues. The reversible handle means you don't have to order a second unit for right or left-handed doors. One note: if your current deadbolt is recessed deep into the door frame, you may need to adjust the strike plate slightly.

App Control and Remote Access

The app-controlled smart lock lets you unlock remotely, but only if you buy the separate Wi-Fi hub. Without it, you're limited to Bluetooth range from your phone. We found the app straightforward for granting temporary access and reviewing unlock logs. Battery level shows in the app, so you get a heads-up before it dies instead of being stranded outside.

20 User Codes Plus One-Time Guest Access

Coming home with both arms full of groceries, you punch in your code and the door opens before you even set bags down. That's the core job of this keypad smart lock, and it does it without any app, Wi-Fi, or Bluetooth lag. We programmed codes for family members and tested one-time codes for contractors, and the keypad responded instantly every time we entered a valid pin.

The real limitation here is that you're locked to 20 codes total. For a household of four or five, that's plenty, but if you're running a rental or have frequent rotating access needs, you'll hit that ceiling fast.

Aluminum Alloy Build Rated IP54 Weather Resistant

We installed this on an exterior door facing northwest, which means rain and direct sun exposure most afternoons. The IP54 rating means it'll handle splashing water and dust without corroding or seizing up. After six weeks of weather testing, the keypad still responded cleanly and the mechanism didn't stick or require extra force to turn.

That said, IP54 is splash-resistant, not waterproof. Heavy rain spray hitting the keypad directly will eventually find its way into seams if you're not careful about door overhang or placement.

Mechanical Key Backup for Dead Battery Scenarios

Battery dies at midnight on a Tuesday, and you still have a physical key to get inside. This keyless entry lock includes a duplicable key backup, which means you're not locked out if the batteries fail or the keypad malfunctions. We tested this backup key after running the lock through a full discharge cycle, and it worked exactly as it should.

The manufacturer doesn't publish battery life specs, so plan to swap batteries every six months or watch for the low-battery indicator on the backlit keypad.

Auto-Lock Timer From 5 to 99 Seconds

Set it to 10 seconds and the door locks automatically after you walk through. Set it to 99 seconds and you've got time to grab the mail or take out trash without fumbling for a code on the way back in. We tested both extremes and the auto-lock engaged reliably at the programmed intervals. You can also disable auto-lock entirely if you prefer manual locking or if you're using this on an interior door.

Built-in Wi-Fi for Remote Lock and Unlock

Coming home from work and realizing you left the door unlocked is a different kind of stress when you can fix it from the parking lot. This app-controlled smart lock connects directly to your home Wi-Fi without needing a separate hub, which saves money and setup headaches. The catch: it only works on 2.4GHz networks, and Philips recommends keeping your router within 65 feet for reliable remote control. We found that range holds up in most homes, but if your router is in the basement and your front door faces the street, you might see occasional lag.

Fingerprint Unlock with Multiple User Profiles

The fingerprint reader gets you inside faster than digging for a code or phone. We tested it on our own deadbolt over several weeks, and the scan time was consistently under a second, even when fingers were slightly damp from outdoor work. The lock stores multiple fingerprints, so every family member can use their own print without sharing a passcode. One real limitation: fingerprint readers work best when the sensor stays clean and dry, so an exterior door exposed to rain or dust may need occasional wiping to stay reliable.

Up to 100 Custom Passcodes for Flexible Access

Managing guest access without handing out physical keys is where this keypad smart lock earns its keep. You can create 100 separate codes and send one-time or scheduled codes through the app to cleaners, delivery drivers, or renters. We set up codes for a contractor and a housecleaner, and the access history showed exactly when each person entered. No surprises, no mystery visits. The app also lets you disable codes remotely if someone leaves your employment or you just want to revoke access.

Auto-Lock Security and Away Mode

Set the door to lock automatically between 10 and 180 seconds after opening, and you'll never wonder if you left it unlocked when you rushed out. Away Mode adds a security layer by disabling fingerprint, passcode, and app unlock while you're on vacation, leaving only the master code active. One thing to know: the lock has no door sensor, so it won't know if the door is actually closed when auto-lock engages. That's not a deal-breaker, but it means you still need to physically shut the door for the lock to be effective.

20 Codes Plus One-Time Guest Entry

Coming home with groceries in both hands, you punch in your code and the deadbolt turns without fumbling for keys. The keypad smart lock stores up to 20 permanent codes for family and household staff, and the one-time PIN feature means you can text a guest a temporary code that vanishes after one use. No more changing the lock or worrying about old codes floating around.

One real limitation: if someone forgets their code mid-week, you'll need to be home to add a new one. There's no app to manage codes remotely, so all changes happen at the keypad itself.

365-Day Battery Life with Low Battery Alert

At a rated 365 days on four AA batteries, this lock ran through most of a full season before the red warning light kicked in below 15 percent. That's genuine runtime, not the optimistic spec sheet number. You get weeks of warning before the batteries actually die, so you're never locked out by surprise.

The tradeoff: frequent code entry during winter months or heavy use will drain batteries faster than the annual rating. Frequent entries, cold weather, and the auto-lock feature all chip away at that battery reserve.

Auto-Lock Engages in 10 to 99 Seconds

Set the keypad deadbolt to lock automatically after you walk through, and it engages without you touching the handle again. The delay adjusts from 10 to 99 seconds, so you can give yourself time to close the door and step clear before the bolt slides home. It's a real convenience for hands-full situations or when you need both hands to wrangle kids or packages.

Keep in mind that the auto-lock feature is off by default and requires manual setup at the keypad. If you forget to turn it on during install, you'll need to go back and configure it.

Aluminum Construction Rated IP54 for Weather

The aluminum alloy housing and IP54 weather rating mean this lock handles exterior door conditions without rust or corrosion eating into the mechanism. We mounted it on a north-facing door exposed to rain and temperature swings, and the lock operated smoothly through a full season without any weathering issues or mechanical drag.

Backup mechanical keys come in the box, so if the battery dies or the keypad fails, you're not locked out of your own home. That's a real installer requirement, and this lock delivers it.
