Smart Locks
Keyless entry that is actually more secure than the key it replaces.
A smart lock removes the most common home security failure: the hidden spare key and the lock that never gets rekeyed. In 2027 the category has split into three clear designs: full deadbolt replacements with keypads, fingerprint models that unlock in under a second, and retrofit units that keep your existing key and deadbolt. All three can exceed the security of a standard keyed deadbolt when installed correctly.
We compared leading models on the factors that determine real-world satisfaction: ANSI security grade, unlock methods, battery life and low-battery behavior, auto-lock reliability, and how deeply each lock integrates with Apple Home, Google Home, and Alexa. A lock that dies without warning or will not talk to your platform is a bad lock regardless of its feature list.
