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

available before beginning this procedure.
Note: Ensure the brake pedal is not

3. Turn the key from the 2 (OFF) position to the 3 (ON) position.
4. Cycle four times rapidly (within six seconds) between the 2 (OFF)

position.
5. Within 20 seconds press any button on the remote entry transmitter.
Note: If more than 20 seconds have passed you will need to start the
procedure over again.
6. Repeat Step 5 to program each additional remote entry transmitter.
