Mechanical keyless entry for commercial doors
The Simplex 919-26D is a heavy-duty mechanical pushbutton combination lock finished in satin chrome. It provides keyless access control without batteries or wiring, making it suitable for commercial and institutional doors where a single shared code is sufficient. The lock allows free egress at all times via the interior thumbturn. It fits doors between 1-3/4" and 2-1/8" thick.
No power draw and silent operation
As a fully mechanical device, the lock draws zero electrical power and produces no electronic noise during operation. The deadlocking spring latch automatically relocks the door each time it closes, securing the opening without motorised components. The clutch-protected thumbturn resists forced manipulation, while the cast front housing and metal exterior trim plate provide physical durability without active cooling or power requirements.
Single-code programming at the keypad
The lock uses a single access code that is programmed directly via the pushbutton keypad without removing the unit from the door. This design suits applications where one combination serves all authorised users, but it cannot accommodate multiple unique codes, audit trails, or remote management. Buyers needing individual user codes, scheduled access, or electronic integration should select an electronic access control system instead.

Questions about this item
How do I install the Simplex 919-26D on a 1-3/4" thick door and what backset step is often missed?
Mortise the lock body for the 2-1/2" inswing or 2-9/16" outswing backset, fit the 5/8" deadlocking spring latch and angle strike, then program the single code via the keypad without removing the lock; the step often missed is selecting the correct backset for the door swing direction.
What maintenance or replacement will the Simplex 919-26D need over time?
The mechanical design eliminates battery replacements; periodic lubrication of the deadlocking spring latch and clutch-protected thumbturn keeps operation smooth, and the cast front housing with metal exterior trim plate resists wear under heavy-duty use.
What is the first limit that appears under sustained use of the Simplex 919-26D?
The single access code cannot be changed per user, so high-traffic doors hit a management limit before the force-resistant, clutch-protected mechanism shows mechanical fatigue.
