Curious... If you get a used car that has keyless entry and it is missing the remote (key fob).. You buy a replacement remote and program it... If someone else has the original ..would it still unlock the vehicle if a replacement has been newly programmed?
Been reading that most, if not all, remotes have to be programmed at the same time.. So if you program a new/replacement remote...the original shouldn't work? (unless programmed at same time) Is this correct?
