Abstract
Apparatus for determining the opening combination of a safe lock including a dial turning device that is controlled by a programmable processor acting through a stepping motor to set selected combinations into the lock and to test the lock after each combination has been set to determine if the lock bolt has been withdrawn to a release position. A readout of each combination set into the lock is provided and the readout is automatically inhibited to identify the opening combination when the lock bolt has been withdrawn to a release position.
