Before you buy this lock

You need to check your door’s backset and thickness before purchasing. This model replaces standard deadbolts, but exact fit depends on your current hardware.

If you want remote access from anywhere, you must buy the G2B Gateway separately. This gateway is not included in the box. You should also confirm your door swings correctly, as the lock is designed for specific handedness. Battery life lasts up to six months on four AA cells. You will need to replace these periodically. Keep a physical key handy as a backup. This lock fits well with video doorbells for a complete entry system. It offers keyless convenience for busy households.
