2121679 9319953 PCTABS00027 A vehicle operated remote control access system (C) for obtaining access to a controlled environment using the headlight system (32) of a vehicle having a high beam operation and a low beam operation. The remote control access system (C) comprises a switching sensor circuit (44, 52, 50, 48, 56) for detecting a sequence of switching from a low beam to a high beam operation or from a high beam to a low beam operation of the vehicle. Two or more of these switching sequences may be employed in the present invention. A timing means (62) is provided with the circuit (44, 52, 50, 48, 56) in order to determine if a switching sequence from a low beam operation and then from a high beam operation back to a low beam operation, and possibly with a second sequence of back to high beam and then low beam operation, occurred within a predetermined time interval. If the one or more required switching sequence did occur in this time interval, then the remote control system (C) is energized to open a gate or a door. If the switching from the low beam to the high beam and back to the low beam did not occur within the predetermined time interval then no energization of the remote control system (C) will occur and the system resets to neutral.
