The dormakaba Simplex 7106 is a fully mechanical pushbutton rim lock for wood doors. It features a surface-mounted 5/8" deadlocking latch, automatic relocking and a built-in latch-holdback function. Enter the programmed combination and rotate the exterior thumbturn for access, while the interior control provides free egress. No batteries, wiring, keys, cards or software are required.
Full Product Description
The dormakaba Simplex 7106 Mechanical Pushbutton Rim Lock provides battery-free combination access using a surface-mounted deadlocking latch. It is specifically designed for wood doors where a mortised deadbolt or tubular latch is undesirable or impractical.
Authorized users enter the programmed combination and rotate the exterior thumbturn to retract the 5/8" rim latch. When the door closes, the spring-loaded latch automatically engages the strike and returns the opening to secured operation.
The 7106 also includes a latch-holdback function, allowing the latch to remain retracted when unrestricted passage is desired. When holdback is released, the lock returns to normal combination-controlled operation and automatically relocks each time the door closes.
Unlike the 7102, 7104 and 7108, the 7106 locking mechanism is mounted on the interior surface of the door. This surface-mounted design reduces the amount of edge preparation required and allows the appropriate strike to be selected according to the door swing:
- Box strike for inswing doors
- Flat strike for outswing doors
Because the Simplex 7106 is completely mechanical, it requires no batteries, electricity, wiring, access cards, software, computer or network connection. It remains operational during power and network outages while eliminating recurring battery-replacement and electronic maintenance costs.
The lock stores one shared access combination. The combination can use one or more of the five buttons pressed individually or simultaneously, providing thousands of possible combinations. Authorized personnel can change the code without removing the complete lock from the door.
Heavy-duty construction includes an all-metal cast exterior housing, vandal-resistant solid-metal pushbuttons and a force-resistant, clutch-protected exterior thumbturn. The clutch helps protect the lock’s internal mechanism if someone attempts to force the exterior thumbturn without entering the correct combination.
The 7106 is field reversible and installs on wood doors from 1-3/8" through 2-1/4" thick. Its weather-resistant construction makes it suitable for appropriate interior or exterior applications. Manufacturer specifications

How Latch Holdback Works
The built-in holdback function allows the 7106 latch to remain retracted so users can pass through the opening without entering the combination.
Holdback Activated
- The rim latch remains retracted.
- The door can be opened without entering the combination.
- The opening operates in unrestricted passage mode.
Holdback Released
- The latch returns to normal spring operation.
- Exterior users must enter the combination.
- The lock automatically secures when the door closes.
Activating holdback does not erase or change the programmed combination.
Latch holdback should only be used where unrestricted passage is permitted. It must not be used to defeat required latching on a fire-rated or otherwise regulated opening.
Surface-Mounted Rim Latch
The 7106 differs from the other Simplex 7100 models because its locking mechanism mounts to the interior face of the door.
Advantages of the rim-latch design include:
- Less door-edge mortising
- Automatic relocking
- Built-in latch holdback
- Strike options for inswing and outswing doors
- Practical installation on many wood-door applications
The 7106 is not an exit device or panic bar and should not be described as exit-device trim.
Deadlocking Latch Protection
The 7106 uses a deadlocking rim latch. When the door is properly closed and the deadlocking feature contacts the strike, the main latch is protected against being forced back with a card or similar object.
Correct latch and strike alignment is essential for proper deadlocking operation.
Strike Selection
Inswing Door
Use the supplied box strike mounted to the interior frame or trim.
Outswing Door
Use the supplied flat strike installed in alignment with the surface-mounted latch.
Confirm the door swing before installation so the correct strike and preparation are used.
