How would I go about (if there is a way) to reprogram a keyless entry thats programmed for another car and get it to work with my car? It's an '05 EX. the dealer gave me an extra keyless entry with the car but its programmed for another car he had on the lot, and he said there is a way to change it to another car but didnt really go into details. If I cant do it, its not that big of a deal but it would be good to have another keyless. Any info would be appreciated, thanks.
