Editor's Pick: No more worrying about whether you remembered your keys—just press your fingerprint and the door opens. If someone needs to stop by, you can send a one-time code remotely without having to rush home. The battery lasts about a year, so once it's installed, you barely have to think about it, and you'll get alerts if anything seems off with the lock.
