BlueAndWhiteClassic Posted September 14, 2020 Share Posted September 14, 2020 I've tried a quick search on here but didn't find anything that seemed to directly answer my question so I hope you don't mind me trying your patience with what must be a common question...I have two ignition keys, each with an immobiliser fob (black, lozenge shaped with a lock and unlock button on the front). The fob I use most often has now stopped working but luckily the other does still work.Is a fob battery change a simple process or does it involve re-programming keys etc?Grateful for any advice.Malcolm Link to comment Share on other sites More sharing options...
garybee Posted September 14, 2020 Share Posted September 14, 2020 Very easy, just swap the battery no programming required. From memory I believe it's a CR2032. Very common button cell available anywhere. Worth keeping a couple of spares. Link to comment Share on other sites More sharing options...
revilla Posted September 14, 2020 Share Posted September 14, 2020 You may find you need to press the button on the key a few times to get it to synchronise before it starts working but that's all. Link to comment Share on other sites More sharing options...

SM25T Posted September 14, 2020 Share Posted September 14, 2020 Yes CR3032. Straight swap and then press unlock around half a dozen times until red LED goes out. Link to comment Share on other sites More sharing options...
