Simplex 5021XSWL-26D Satin Chrome US26D Mechanical Pushbutton Door Lock

Mechanical Pushbutton Lock With Key Override

The Simplex 5021XSWL-26D is a heavy-duty mechanical pushbutton lock designed for commercial doors. It provides exterior access by combination while allowing free egress at all times. The lock operates without batteries or wiring, using a single access code programmed at the keypad. It suits buildings that need a standalone, code-based entry solution with a physical key backup.

Grade 1 Certified With 3-Hour Fire Rating

This lock meets ANSI/BHMA A156.2 Grade 1 standards for heavy-duty use and carries a 3-hour UL/ULC fire rating for "A" label doors. It fits doors ranging from 1-3/8" to 2-1/4" thick with a 2-3/4" backset. The cylindrical latch has a 1/2" throw and a floating faceplate. The Schlage "C" keyway key override works only with compatible K-I-L Kaba cylinders, limiting cylinder choices to that specific format.

Surface-Mount Installation With Keypad Programming

Installation follows a standard cylindrical lock prep without wiring through the door. The access code is changed at the keypad without removing the lock from the door. Solid cast housing and levers resist wear in indoor and outdoor settings. ADA-compliant levers meet accessibility requirements. Installers must verify the existing door prep matches the 2-3/4" backset and confirm the key cylinder is a Schlage "C" K-I-L Kaba type, otherwise the key override will not function.
