Electronic lock uses a mobile phone

E-Lock is a touch tone activated electronic combination lock which is controlled by the keypad of a mobile phone. When the correct combination is entered, a relay on the E-Lock circuit board is activated. The relay can be connected to a solenoid (not included) controlling the lock on a door or cupboard. To operate the E-Lock, just hold your mobile phone close to the built in microphone and then enter the lock combination on the phone keypad all at apogge kits
