Here's a stupid question - if you change the battery on your keyless entry fob, do you have go thru the reprogramming rigamarole again? I have an aftermarket Remocon RMC-105 fob that I bought a couple of years ago after losing an OEM keyfob for my '96 Mystique. I need to change the A23 battery in it, and can't find any info on whether it will need to be reprogrammed (you know, the paperclip jumper behind the glove box).
