Simplex mechanical pushbutton locks by dormakaba offer reliable keyless access without cards, wires, or batteries. These locks are trusted in commercial and residential applications for their durability and simplicity.
Advantages:
Disadvantages:
Unlike standard keyed locks, Simplex mechanical locks are rekeyed by changing the entry code. This makes them ideal for quick re-securing without hardware replacement.
Changing the combination can be done without removing the lock from the door, but requires following specific steps depending on the model. We recommend professional help to avoid lockouts or misprogramming.
Price range: $50–$100 depending on the model and service complexity.
While most Simplex locks are mechanical, dormakaba offers digital models like the PowerPlex series. These locks combine code-based entry with audit trails and multiple user codes.

Retrofit options are available to upgrade older mechanical Simplex locks to digital keypads with memory and access control.
