Cheap smart locks for keyless entry

Going keyless costs less with the cheap smart locks gathered here. Keypad deadbolts, fingerprint models, lever handles and retrofit units that fit over an existing lock are listed, a handy upgrade for families juggling spare keys or hosts welcoming short-term guests.

Will cheap smart locks fit your door?

• Before picking a smart lock, measure door thickness and backset, and see whether only the interior side or the whole deadbolt gets replaced.
• Compare entry methods such as keypad, fingerprint, phone app and a physical key backup, based on who needs access.
• Battery details are easy to miss on smart lock listings, so check the type, low-power warnings and any emergency power contact.
• An ANSI/BHMA grade printed on the packaging gives a standardized indication of the deadbolt's durability and strength.

Which suits you: Renters may prefer retrofit locks that keep the existing exterior keyway, while homeowners can install full keypad deadbolts with separate codes for guests and family.
