Overview
Securing an entry door is the job of this Kwikset deadbolt, a metal single cylinder lock in satin nickel. Mounting hardware and an installation manual come in the box.
A resettable lock and a plain mechanical design suit front doors and interior rooms that need a key. The listing never gives backset, door thickness or bore sizes, so fit is unconfirmed.
Who it's for
Exterior doors and rooms where a key lock is wanted. Buyers with unusual door preps should measure before ordering.
Pros and cons
- Key outside, thumb turn inside
- Hardware and manual included
- Door prep sizes not stated
- Single cylinder only
- Not a smart lock
Performance notes
Keying happens on one side only, while the opposite side turns by hand. The bolt locks the door into the frame, so frame strength matters as much as the lock. Resettable means the lock can be re-keyed.
