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).
I strongly abide by the motto, "Safety third."
I thought what I'd do was, I'd pretend I was one of those deaf-mutes.
Works fine now. The old A23 battery was down to 11.7 volts; the new one hits 12.6 V. I've had 12V batteries in garage door openers that still worked at as low as 7 volts, but I guess this system is just twichy-er.
I believe the car is programmed to the remote, not the remote to the car. So the code for the key fob is actually stored in the car.
