Keyless entry push button

sit in car keep doors closed then turn the key to the on position then off position 8 times ending in the on position. your car doors should lock then unlock at that time hit any button on the key fob your doors will lock and unlock again if youve done it right at that time turn the key back to off position remove from ignition and test your key fob if it doesnt work make sure the battery in the fob is good and then try again.

that is by the way for the key fob, obviously if your talking about the buttons on the outside of car door then what i said will not work.
