Keyless Transmitter (FOB)
I know this has been hashed over before BUT I think my problem may be different. Thought I'd do some preventive maintenance & change the battery in the fob. Went by the manual, steps 1 - 5. Fob won't unlock doors & trunk. The battery is CR2032. Changed to old battery. Dead. Wife's fob works ok. Dealer says he'll reprogram it for $100.
Tried the glove box pocket. Car will start but when I exit the car, can't unlock doors. Any input will be greatly appreciated.

Put the new battery in the fob and program using the user's manual. That's what the dealer will be doing.

The fob should not need reprogramming, no matter what.
Be sure you're putting the battery in the fob with the positive side down. If that's not it, then buy another battery and try it. $2 -$3 for an extra fob battery is better than $100 to the dealer.

Apparently RayOvac is a no-no.
When replacing the CR2032 fob battery, be sure to get one that has a smooth negative side face.
Avoid Rayovac, as the negative surface is gridded (similar to knurled) and will not make constant nor consistant connectivity with the tiny spring in the fob.
When my original fob battery died and Rayovac was the replacement, I thought I'd damaged the fob itself during the changeover. It would only work sporadically and fear of the "No fobs detected" message was often. The battery checked fine with a volt meter and worked perfectly in two other devices, but not in the fob. After 3 weeks of frustration, including squeezing, banging, beating, and shaking the fob to get it to work, just using a smooth face battery from one of my other devices cured the problem.

I've changed out both fob batteries with Energizer's and had no problem's. As mentioned the Ray-O-Vac's have a textured surface, and sometime's don't make proper contact. If you have one working fob, you can do the reprogramming yourself with the with the method shown in the owner's manual. You may need the rear hatch metal key, depending on the proceedure you use.

But I never had to reprogram any of my fobs when I replaced the battery in them.
