Described herein is a locking device which integrates mechanical components in a hollow metal door frame with electronic access components. The preferred embodiment comprises a magnetic field generating device, an appropriately shaped metal solenoid housing and a cam retaining locking bar attached to a hollow stem. The electronic components override the original mechanical components of the lock to create a fail-safe situation in which the original mechanical lock may be disabled. In the preferred embodiment, my upgraded locking device can be re-installed within a hollow door frame, thereby minimizing service costs and doorframe modification costs.
