Do you have a new key? If so, the following should do the trick:

-Close all doors and have all keys available.

-Using key number 1 (your key that doesn't need to be initialized), turn the ignition to switch to position 2, then switch off within 5 seconds and remove the first key.

-Within 30 seconds of turning the ignition switch to "off" Press and hold the arrow button.

-While holding the arrow button, press and release ("tap") the roundel button three times within 10 seconds.

-Release both buttons simultaneously. The doors will immediately lock and unlock signaling initialization.

-If additional keys need to be initialized, repeat steps 3-5 within 30 seconds.

-Then stick the key that has just been initialized into the ignition and turn to position 2. Programming is now complete!
