Full Product Description Secure offices, stockrooms, employee entrances and other controlled areas without managing batteries, electronic credentials or network connections. The dormakaba Simplex 5021 and 5041 mechanical pushbutton locks provide reliable combination entry through five mechanical buttons while allowing authorized personnel to bypass the combination using the configured key cylinder. Both models support one access combination that can be changed at the door without removing the lock from the door. The 5021 and 5041 use an exterior combination-change procedure, allowing authorized personnel to manage the code from the keypad side while following the proper combination-change process. From inside, occupants can operate the lever at any time for immediate, unrestricted egress. During standard operation, the exterior lever returns to its locked condition after entry, helping prevent unauthorized access without requiring users to manually relock the door. The important difference is passage operation. The Simplex 5021 does not have passage mode and is designed for openings that should remain secured from the exterior. The Simplex 5041 includes passage mode, allowing the door to remain accessible without entering the combination during business hours, meetings, deliveries or other periods of high traffic. Passage mode can then be disengaged to restore controlled combination entry. Because these locks are fully mechanical, they require no batteries, electrical wiring, programming software, Wi-Fi or subscription fees. Their rugged standalone design makes them an excellent choice for commercial facilities seeking dependable access control with minimal ongoing maintenance. Both models use a 2-3/4-inch backset cylindrical latch with a standard 1/2-inch latch throw. Multiple key-override formats, lever styles and architectural finishes are available, allowing the lock to coordinate with many existing commercial key systems and door-hardware specifications.

Entry requires either the correct pushbutton combination or an authorized override key. The 5021 is ideal for stockrooms, utility rooms, offices, equipment rooms and other areas where unrestricted exterior access is not required. Simplex 5041 – Combination Entry With Passage Choose the 5041 when you need the same mechanical combination entry and key override capabilities with the addition of passage mode. When passage mode is activated, the exterior lever can be used without entering the combination. This is useful for doors that should remain accessible during scheduled business hours and secured again afterward. How the Locks Work For normal entry, the user presses the correct button combination and turns the exterior lever to retract the latch. The lock’s mechanical mechanism does not require batteries or electronic programming. Authorized personnel can also use the configured key override to gain access without entering the combination. Key override does not erase or change the programmed combination. The interior lever remains operational for immediate free egress. On the 5021, the exterior side remains in controlled-entry operation. On the 5041, passage mode may be activated when unrestricted exterior access is needed.
