1. Start with the following conditions:
a. Key is out of the ignition
b. Driver door is open (all other doors are closed)
c. Driver door is unlocked (other door locks don’t matter).
2. Insert the key into the ignition (don’t turn it) and pull it out.
3. Do these steps in 40 seconds:
a. Perform 5 lock/unlock cycles starting with lock using the power door locks. A lock/unlock cycle consists of pressing the power lock switch, followed by pressing the power unlock switch on the driver’s door panel.
Use an even pace and try to go relatively fast.
b. Close, then open the driver’s door.
4. Do these steps within 40 seconds:
a. Repeat step 3a (just as you did previously).
b. Put the key in ignition.
c. Twist the key in the ignition to ON (as far as without starting the engine), then back to OFF position.
d. Remove the key.
5. Within 3 seconds, the power door locks should cycle (lock then unlock) automatically which means you're system has entered programming mode. Start from the top if door locks did not cycle.
6. Perform these steps within 40 seconds:
a. Press the LOCK and UNLOCK buttons on the first transmitter simultaneously for 1 second and release.
b. Immediately after letting go of the LOCK and UNLOCK buttons, press the LOCK button by itself and release. Within 3 seconds, the door locks should cycle (lock then unlock) once indicating successful programming. If the door locks don’t cycle, or cycle twice, repeat steps 6a and 6b as the remote has not been accepted.
c. Repeat steps 6a and 6b for each transmitter that will operate the vehicle, including any old transmitters.
7. Close driver door.
