Extended version of the Dimex K821 direct dialing tool

This is a simplified version of a tool that directly identifies genuine and false notches using professional techniques and then manipulates the lock plates. It retracts the bolt to achieve the unlocking action.
It can open: Dormakaba 71111/71113
and the Dimesi K821 shown in the picture.

This tool requires the operator to have a certain level of skill and dexterity.
