Each transmitter has a unique Vehicle Access Code (VAC) that changes every 5 seconds. If a transmitter or receiver is replaced, each transmitter must be programmed to the vehicle's receiver. Entering a specific button sequence on the DIC, up to 3 transmitters can be programmed into the receiver. After programming the transmitters to the vehicle, the receiver will update this code every 5 seconds in order to match the code programmed in the transmitter.

The transmitter may not communicate or become out of synchronization with the receiver if any of the following situations occurs:

The transmitter battery is disconnected.
The vehicle battery is disconnected.
The transmitter and the vehicle are separated for 2 weeks or more.
The receiver is disconnected.

Perform the synchronizing procedure if the transmitter does not communicate or becomes out of synchronization with the receiver. If the transmitter and/or receiver are replaced, preform the following programming procedure:
