ignition - do not turn it.
2. Hold the UNLOCK button on the driver's side door - DO NOT RELEASE until
instructed to do so in step 4.

twice. (Do not start the car, ON is the position just before starting and OFF is
where you can remove the key).
4. RELEASE the UNLOCK button. The locks will
now cycle from lock to unlock signaling the vehicle has entered programming
***If the locks cycle before you release the
unlock button, the programming will not work and your vehicle is not in

releasing, the procedure is not being followed correctly or something is
malfunctioning with the vehicle???s keyless entry system.

at the same time on the first remote you wish to program. Hold the buttons down
together until the vehicle responds by cycling the door locks (you may have to
hold the buttons down for up to 5 minutes when programming a new remote ??? a
previously paired remote will pair more quickly). Repeat step 5 above for any additional
or existing remotes that you wish to program and use on the vehicle at this

exits programming mode. Programming is now complete. Test all remotes.
