Dormakaba 904-26d-41 Pushbutton Deadbolt Satin Chrome

Product Description

The DORMAKABA 904-26d-41 is a mechanical pushbutton deadbolt lock designed for doors ranging from 1-3/4 inches to 2-1/8 inches thick and finished in satin chrome. Part of the Simplex 900 series, it delivers fully mechanical access control without batteries, electronics, or external power of any kind. A single access code is programmed directly through the keypad without removing the lock from the door. The interior thumbturn allows free egress at all times. Because this is a deadbolt model, it must be manually relocked after each entry. Locksmiths, access control installers, and commercial door hardware technicians are the primary trades that install and service this hardware.

This lock is suited for commercial and light institutional applications where keyless entry is required but electronic infrastructure is not available or not desired. Typical installations include office interior doors, storage rooms, utility closets, and any controlled-access opening where eliminating key management overhead is a priority. The mechanical design removes ongoing costs tied to issuing, auditing, and collecting keys or access cards. It is also a practical fit where battery-dependent hardware is impractical due to maintenance schedules or environmental conditions.
