These are some programming instructions I've found although I have not yet to test them on my vehicle.
1) Make sure that the key is not in the ignition, the doors are unlocked, and the driver's door is open.
2) WITHIN 5 SECONDS, without turning, insert and remove key from the ignition twice. (leave key out)
3) WITHIN 40 SECONDS, Close and open the driver door twice. (leave door in open position)
4) Again, insert key into the ignition and remove it. This time only once. (leave key out)
5) WITHIN 40 SECONDS, Close and open the driver door twice, then close the door.
6) Insert key into the ignition and leave it in the LOCK position.
You have now entered programming Mode.
Within 40 seconds.
A. Add mode:
A1) Turn the switch ignition (key) to "ON" for 1 second, then turn back to "LOCK".
AA1) This will retain the original codes; or
AA2) Repeat step A1 once (total 2 times) to program a remote transmitter code while erasing the original Codes; or
AA3) Repeat step A1 twice (total 3 times) to check how many remote transmitters are currently registered.
AA4) Repeat step A1 four times (total 5 times) to erase all registered codes.
A2) Remove the key.
A3) You’ll hear the doors "LOCK" and 1 second later "UNLOCK" (just listen) A4) On your remote, press the lock and unlock buttons simultaneously for 1 to 1˝ seconds, then let go.
After this step I found two different directions or versions.
Within 3 seconds.
A5) On your remote, press lock button.
sytem should now lock and unlock vehicle once to confirm registration, twice to indicate registration failure.
Within 40 seconds.
A6) Repeat button procedure to program remaining remote transmitters.
A5) On your remote, IMMEDIATELY press unlock by itself.
A6) You’ll get one of three responses:
R1) You’ll hear the doors "LOCK", then "UNLOCK" once. The remote is accepted. If you want to program another remote, immediately proceed to step A4 with your second remote, otherwise open the driver’s door and the remote is registered.
R2) You’ll hear the doors "LOCK", then "UNLOCK" twice. Either you didn’t use the same remote in steps A4 and A5(not likely), or this remote was already registered. The timing was off when you pressed the LOCK and UNLOCK buttons simultaneously and then UNLOCK by itself. Immediately press the two buttons together and the unlock by itself again. Keep trying until you get the locks to signal once that you have been successful. Then if you have another remote to program, quickly press its' buttons as before, until you hear the locks signal once. When you are finished, open and close the driver door to lock in the programming.
R3) If no response, go back to step 1 near the beginning of these instructions.
To exit Programming Mode: Open driver door. A maximum of 4 remote transmitters can be programmed.
Al informed earlier I have not tested neither versions, since I not cut my new key yet.
