Abstract
A wireless unlocking system includes a programmable telephone. When the programmable telephone receives a call from a communication terminal along with a calling telephone number, the calling telephone number is matched with a number of pre-stored telephone numbers. The programmable telephone transmits an unlocking signal to an electrically controlled lock and unlocks a door if the telephone number of the call successfully matches one of the pre-stored telephone numbers.
