ATTENTION: To program your new and existing remote follow all steps provide below. And, in order to place your system on programming mode, the Valet switch/button must be plugged into the BLUE port of the receiver.

2. Turn ignition ON using your key.
3. Within 5 seconds press the Valet button /switch the number of times corresponding to the desired channel as seen on the picture below, then press and hold it. Your LED will flash the same number of times you pressed valet button and you’ll hear a chirp to confirm the system’s programming mode. DO NOT release the button.
4. Press the button on your remote that you’d like to assign to that channel. You’ll hear another chirp to confirm that the remote has been paired.
5. Remove the key once you’re finish.

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.
