The button 4 may be spring biased out of the main body 2 and have locking arms (13, Fig. 4) for retaining the locking elements. Solenoid (15, Fig. 4) may have a spring biased locking pin (14) for retaining the button 4 in the locked position. There may be a mounting plate 3 for attachment to the back of the door for securing the apparatus to the door. There may be a keypad 5, data transfer interface 30, circuit board and processor (16, 17, Fig. 2) for controlling the solenoid to withdraw the locking pin.
