Replacing lost remote entry transmitters
If you would like to have your remote entry transmitter reprogrammed
because you lost one, or would like to buy additional remote entry
transmitters, you can either reprogram them yourself, or take all
remote entry transmitters to your authorized dealer for
reprogramming.

How to reprogram your remote entry transmitters

You must have all remote entry transmitters (maximum of six)
available before beginning this procedure. If all remote entry transmitters
are not present during the programming procedure, the transmitters that
are not present during programming will no longer operate the vehicle.
Note: Ensure the brake pedal is not depressed during this sequence.
To reprogram the remote entry transmitters:
1. Ensure the vehicle is electronically unlocked.
2. Put the key in the ignition.
