Dormakaba Simplex 7100 Series 7108 Pushbutton Lock, 2-3/8 Backset

The Simplex 7108 is a fully mechanical push button deadbolt lock from the dormakaba Simplex 7100 Series, set up with a 2-3/8 inch backset. If you've shopped this lock before under the Kaba or Kaba Ilco name, it's the same product: Kaba's Simplex line is now branded dormakaba, so "kaba Simplex 7100" and "dormakaba Simplex 7100 deadbolt" point to this exact lock. It gives you keyless entry by combination on the outside and free exit by thumbturn on the inside, with no batteries, no wiring, and no key to track.

How the Simplex 7108 works

This is a mechanical lock, which is the whole appeal. There's no battery to die and no power to run. Someone enters the door by pressing the single access code on the solid metal pushbuttons, and the deadbolt retracts. From inside, the thumbturn always operates freely, so egress is never blocked. The 7108 is the deadbolt configuration, and as a deadbolt it relocks manually: you throw it when you want the door secured. That makes it a primary or auxiliary lock for openings where you want deliberate, code-based access rather than a door that locks behind everyone automatically.

You program the access code right on the door through the keypad, without pulling the lock off. One code covers all users, which keeps day-to-day management simple. There's no software, no enrollment, and nothing to charge.

Why choose a mechanical Simplex lock

The Simplex pushbutton platform exists to solve one expensive problem: keys and credentials. Issuing keys, collecting them when someone leaves, rekeying when one goes missing, all of that has a cost. A Simplex lock replaces it with a code you can change yourself in minutes. Compared with electronic keypad locks, the 7100 Series goes a step further by dropping batteries entirely, so there's no power maintenance over the life of the lock. For light commercial and residential doors like offices, storage rooms, side entrances, and interior controlled doors, that combination of keyless access and zero power dependency is exactly why facilities have specced the Simplex 7100 for decades.

One thing to match before ordering: the 7108 is the 2-3/8 inch backset deadbolt. Other 7100 models cover a 2-3/4 inch backset (7102) and a deadlocking latch that auto-relocks (7104). Confirm your backset and whether you want manual-relock deadbolt or auto-relock latch behavior.
