ABSTRACT:
A keyless entry system comprises a locking key holder having a key lock pin, an actuator for operating the key lock pin, and a controller which detects a unique identification code of the authorized user and a preset identification code and outputs an activating signal for operating vehicular devices, such as a door lock and/or the actuator. The key may be safely kept in the locking key holder and cannot be removed therefrom unless the unique code has been received. Thus, the necessity for the user to carry a mechanical key is eliminated.
