unofix Posted September 29, 2021 Share Posted September 29, 2021 Hi Tracy, I'm very surprised that on a 2021 car you needed to replace the keyfob battery. If after replacing it with a brand new CR2032 the keyfob is not working I would think either the battery is not in correctly, or that the replacment battery is faulty. Since the car is so new then there should be no charge to sort out a none working keyfob. Quote Link to comment Share on other sites More sharing options...
anon Posted September 29, 2021 Share Posted September 29, 2021 Luckily, my company makes a product with an inbuilt PC board from which I have to remove the BIOS battery. I've got plenty of 2032 cells and can change one in a Ford keyfob in less than a minute. Quote Link to comment Share on other sites More sharing options...
Flick Posted August 6 Share Posted August 6 Changed my key fob battery twice now because I read that batteries can be duds, Still the same annoying message every time I start the car. Have just spotted the "open and close the car manually with your car key three times" trick - and it works !! Isn't the web great.
