try this:

1- all doors closed and locked except drivers door (open and unlocked)
2- place key in ignition turn it to on and off
3- cycle the manual door lock from unlock to lock 5 times
4- closed the driver side door and open the driver side door
5- perform step 3.
6- place key in ignition and turn it on to off (one time to add a key) on and off two times ( rewrite ) pull key out of ignition, the door lock should response by going to lock and unlock( one time to add key) lock and unlock two times for rewrite mode.
7- push lock and unlock bottom on key together for 1 sesond and push unlock one time.

YEEESSSSSSS FINALLY GOT IT DONE. Epic your instructions actually worked. the ones i had said to just put the key in the ignition but not to turn it to the on position. One thing also that i think stopped me from being able to program it was that the trunk lock was set on. For some reason when i unlocked that it actually worked
