Abstract
A remote control device for operating vehicle locks having a transmitter for transmitting a remote control signal. The transmitter converts keyword information into pulses of corresponding pulse widths and then pulse modulates these converted pulses prior to transmission as a remote control signal. A receiver is provided for demodulating and decoding the signal and comparing it to a preset code. If the signal corresponds to the preset code an execution signal is generated to produce the locking and locking function.
