Sit in the driver's seat with all doors closed, with your foot off the brake. Pressing the brake pedal at any time exits the programming mode. Insert the key in the ignition. Turn the key from the off position, where it is possible to remove it from the ignition, to the on position, just before the point where it engages the starter, eight times within 10 seconds. Leave the key in the on position. The doors should lock and unlock to indicate the vehicle is in the programming mode.
Within 20 seconds, press any button on the fob. The locks should repeat the lock and unlock process to indicate the fob is ready for use.
Repeat the programming step for all existing and new fobs. Up to four fobs are allowed for each vehicle.
Turn the key off and remove it from the ignition. When you turn the key off, the door locks and unlocks a final time to indicate programming is finished and the vehicle is no longer in the programming mode.
