Single cylinder deadbolt for residential doors

This Yale 820-605 is a New Tradition single cylinder deadbolt with a polished brass US3 finish. It operates from the outside with a key and from the inside with a "T" turn. The solid brass 5-pin cylinder uses a Kwikset KW1 keyway and is keyed different. It carries A156.5 ANSI/BHMA Grade 3 certification.

Suits standard interior

This deadbolt fits doors 1-3/8" to 1-3/4" thick with a 2-3/8" backset and standard 2-1/8" face bore. It is not for doors outside that thickness range or for projects requiring a double cylinder deadbolt. Buyers needing a unified key system across multiple locks should verify keying options before purchase.

2-3/8" backset determines compatibility

The backset is the distance from the door edge to the centre of the bore hole. This lock requires a 2-3/8" backset and will not align with the common 2-3/4" alternative. Confirm your door preparation matches this measurement before ordering.

Questions about this item

Which Yale 820-605 variant should I pick for a standard interior door?

This single model 820-605 fits doors 1-3/8" to 1-3/4" thick with a 2-3/8" backset, so it covers most residential doors without needing another version.

What does the ANSI/BHMA Grade 3 rating mean once the lock is installed?

Grade 3 confirms the deadbolt meets basic residential security and durability requirements under the A156.5 standard.

How does the Kwikset KW1 keyway affect key compatibility?

The KW1 keyway accepts Kwikset-pattern keys, so a locksmith can re-key it to match existing Kwikset locks in the same house.
