Patent attributes
An interchangeable electronic lock includes an electronic access system to activate a motor which powers a gear assembly in the electronic lock. An optional manual bypass allows an operator to override the electronic access. When the lock is activated, the operator manually cranks a lock shaft to lock and unlock a storage unit. A controller selectively operates the motor to move the gear assembly in a linear direction. The gear assembly engages a first portion of a drive assembly with a second portion, to permit manual operation of the lock shaft to lock and unlock the storage unit. An optional modular chassis assembly includes a removable array of components for testing, maintenance and repair. The invention includes a system for operation of the electronic lock, a method of operating the electronic lock and software for operating the electronic lock.
