My suggestion would be call the company that makes the keypads, and find out if there's any way to reset it. I doubt it, as if this were possible, it would make car thieves job much simpler. If getting a hold of the owner is out of the question, and you really want that sort of keyless entry, take them off and buy new ones. JCWhitney, AutoZone, are just a few places I can think of that sell them.
