Abstract
An exemplary system includes a mechanical key and an access control device. The access control device includes a housing defining a keyway that has a fixed position within the housing. The access control device further includes a root depth sensor assembly, an insertion depth sensor assembly, a control assembly in communication with the sensor assemblies, and an electronic lock device. The control assembly is configured to determine the bitting code of the mechanical key based upon information received from the sensor assemblies, to compare the bitting code of the mechanical key to a lock/unlock bitting code; and to transmit a lock/unlock command in response to the bitting code matching the lock/unlock bitting code. The electronic lock device is configured to transition between a locked state and an unlocked state in response to receiving the lock/unlock command and without requiring rotation of the mechanical key.
