Programming Instructions Programming your new transmitter: Enter the vehicle, and turn the ignition switch to the ON position. Press and release the programming button 3 times. Press and hold the button of the transmitter you wish to program for 3 seconds, or until the parking lights flash one time, indicating the transmitter has been programmed to the system. Repeat step 3 for each transmitter up to a total of 4. It is important to remember that during programming, each individual step of the procedure must be executed within 15 seconds of the previous step. When the 15 second time limit is allowed to expire, the system will automatically terminate the programming mode. Additionally, the system will store codes from up to 4 different transmitters. If a 5th transmitter is programmed to any receiver channel, then the first transmitter programmed to that channel will be erased from the system’s memory.
