i only googled and found this info:

1) Sit in the car with the engine off and your driver side window rolled down. (so you have access to the outside lock)

2) Insert the new key into the ignition.

3) Insert the little valet key in the driver side door lock (outside the car)

4) Turn the valet key like you are locking the car, but hold it there.

5) While holding the outside key in lock, press the unlock button on your new remote for 2-3 seconds.

6) Let go of the button.

7) Press the unlock button again for 2-3 seconds. Now the code should register.

8) Let go and you should hear an acknowledgement beep. (the alarm honk/beep)
