hmm, cant remember if there is a button to hold down, but you turn the key to the ON position, and back off, three times. and it will lock and unlock the doors, and pop the deck lid. when it does that, hold down the lock and unlock buttons on the first remote till the locks lock and unlock. then hold down the lock and unlock bottons on the second remote till the locks lock and unlock. then start the car, and makesure they work.
