To program your remote just follow these steps:
1) Turn the ignition switch to ON.
2) Press the valet button 3 times.
3) Press and hold the button on the remote for 3 seconds, or wait until the parking lights flashes.
4) If you have another remote just repeat step 3.
If your vehicle’s system was installed without the valet switch you can order one and install it to make it easier to do the programming.
