Overview
A double cylinder lets a key throw and retract the bolt from either side of this Kwikset deadbolt, so the inside has no thumb turn. The brass body carries a matte black finish, and the mounting hardware is included.
Keyed access on both sides is the reason to buy. The limit is safety: nobody inside can open it without a key, which some local fire codes do not allow.
Who it's for
Owners who need a keyed deadbolt on both faces of an exterior door, and have confirmed local code allows it, get a brass lock tested above the stated ANSI/BHMA grade. Anyone needing quick escape from inside should choose a single cylinder.
Pros and cons
- Keyed on both sides
- Exceeds Grade 1 test requirements
- Reversible for either door hand
- Mounting hardware included
- No inside thumb turn
- Fire code may restrict use
- Keys needed from the inside
Performance notes
A bolt thrown by a key on either face means both sides need the key, which removes the inside thumb turn. Brass construction and testing above the stated grade requirement point to a heavy-duty lock. The latch faceplate comes in drive-in, round corner or square corner forms.
