Best Smart Locks
Fumbling for keys in the dark with grocery bags in both hands? That's the exact moment you'll wish you had a smart lock. Beyond the convenience, you get remote access control and a log of who comes and goes. Modern smart locks support fingerprint, keypad, smartphone app, and physical key backup. We compared them on security grade, smart home compatibility, battery life, and how easy they are to install. The market has matured a lot, and most models now support Matter -- the universal smart home standard that plays nice with Apple HomeKit, Google Home, and Alexa. The Yale Assure Lock 2 Plus leads our picks with Wi-Fi built in and Apple Home Key support, so no separate hub needed. The eufy Security Video Smart Lock S330 is interesting because it combines a lock with a built-in camera. Installation is straightforward if your door already has a standard deadbolt. Most models only replace the interior assembly, so your exterior keyhole stays put. Budget about 30-45 minutes for your first install with basic tools. Battery life ranges from 6 months to over a year depending on how feature-heavy the lock is.

Frequently Asked Questions
Are smart locks secure enough for a front door?
Yes. The Yale Assure Lock 2 Plus carries an ANSI/BHMA Grade 2 security rating -- same grade as quality traditional deadbolts. And honestly, smart locks add features that regular locks can't touch: auto-lock, tamper alerts, and access logging. They're arguably more secure overall.
Do smart locks work if the power or internet goes out?
They run on batteries -- typically lasting 6-12 months -- so power outages don't matter. If your internet goes down, you lose remote access, but the lock still works locally via fingerprint, keypad, or physical key. The lock itself never depends on Wi-Fi to let you in.
Which smart lock works with Apple HomeKit?
The Yale Assure Lock 2 Plus and the Aqara Smart Lock U200 both support Apple HomeKit natively. The Yale also works with Apple Home Key, so you can unlock with a tap of your iPhone or Apple Watch -- just like tapping a transit card. Pretty slick.
Can I install a smart lock myself without a locksmith?
Most smart locks are designed for DIY install -- 30-45 minutes with a screwdriver. They replace the interior part of a standard deadbolt. If your door has a non-standard lock or you need to drill new holes, that's when you might want a locksmith for the initial setup.
