Overview
A keyed exterior knob and single cylinder deadbolt sold as a matched combo set in satin nickel, with all locks keyed alike so one set of keys opens both. It is built for doors 1-3/8 to 1-3/4 inch thick with an adjustable 2-3/8 to 2-3/4 inch backset.
Pairing a keyed knob with a deadbolt on one entry door is a common security upgrade over a knob only lock, and having both keyed alike means carrying one key instead of two. The KW1 keyway is not rekeyable, so a locksmith cannot recut it to match existing house keys later.
- Keyed-alike knob and deadbolt combo
- 3 keys included, KW1 keyway
- Fits 1-3/8 to 1-3/4 inch door thickness
- Satin nickel, all metal construction
Who it's for
Homeowners upgrading a front or side entry door who want a knob and deadbolt that share one key. Not for anyone who needs to rekey the set later, since the KW1 cylinder is not rekeyable.
Pros and cons
- Knob and deadbolt keyed alike, one key for both
- Adjustable backset fits standard door thickness
- All metal construction in satin nickel
- KW1 keyway is not rekeyable
Performance notes
The knob and deadbolt in this set share the same KW1 keyway and ship with 3 keys that work both locks, which is the main point of buying them together rather than separately. The lock body measures 2.54 inches across and the latch backset adjusts between 2-3/8 and 2-3/4 inches, fitting standard doors from 1-3/8 to 1-3/4 inch thick. One install note worth flagging: the mounting screws come preinstalled in the handle and need to be removed before fitting the knob.
