Abstract
A door lock includes an electronic keypad and magnetic card reader arranged to send coded signals to a central processing unit that controls a solenoid latch located proximate to the locking bolt. When the solenoid is energized by a signal from the central processing unit (or an auxiliary switch) the locking bolt can be operated from the locked position to the unlocked position; otherwise the solenoid latch prevents the bolt from being operated.
