The Best Smart Locks of 2025: Reviewed and Tested

Smart locks are a highly visible part of your home that you’ll use just about every day, so it’s important to find a reliable pick that meshes well with your smart home. Here are the factors you should be thinking about as you shop.

Full deadbolt or retrofit

Most smart locks will replace the entirety of your existing lock, including the interior thumbturn, the exterior keyhole, and the deadbolt in the middle. Locks like those will also come with their own keys, which will replace the ones you’re using now.

Others, like the August Smart Lock, and the Lockly fingerprint model, are designed instead to work with at least some of your existing lock hardware. With a retrofit lock like that, you probably won’t need new keys at all, and you might not even need to swap out the deadbolt. Locks like those can sometimes be a better fit for apartments, where the building owners might not allow you to replace the entire lock.

Modes of access

Different smart locks will take different approaches to letting you in. On a basic level, most smart locks will let you lock and unlock the door wirelessly from your phone, using an app. Others add in keypads for coded entry, which can help you rely on your keys a little less while also making it easier to share access with others. Some of the newest smart locks add in touch sensitivity or fingerprint scanning to let you inside with just a tap. Apple has also added a Home Key feature in iOS15 that lets you store a digital house key in your Apple Wallet, which lets you open compatible smart locks using the NFC radio in your iPhone or Apple Watch.

It may be overkill to pay up for a smart lock that offers all of that, so it’s fine to dial in on the mode of access that interests you most. You’ve got a diverse mix of options these days.
