Up to three transmitters may be programmed to one remote control door lock receiver (Omron Module). A transmitter may be programmed to more than one vehicle if the remote keyless entry systems are similar. All of the transmitters (maximum of 3 total per receiver) must be programmed at the same time in order for all of the transmitters to function properly. Once all three memory locations are occupied in the receiver, programming of an additional new transmitter will cause the first programmed transmitter to be erased.

Important: Leave a window down in the vehicle while reprogramming the remote control door lock receiver system. The above action will prevent unintentional lock out if the reprogramming procedure is not performed properly.
