1. Turn the ignition from OFF to ON eight times within 10 seconds, ending in ON. If the GEM has successfully entered program mode, it will lock and unlock all the doors.
2. Press any button on a transmitter, and the doors will lock and then unlock to confirm that each transmitter has been programmed.
3. If the door locks do not respond for any transmitter, wait for several seconds and press the button again.
4. Turn the ignition switch to the OFF position, or wait up to five minutes after step 1, to exit program mode. If a transmitter has been programmed (or reprogrammed), the GEM will lock and unlock all the doors one last time.
