andy1741 Posted February 20, 2019 Share Posted February 20, 2019 Hi All, MK2.5 Focus Zetec 1.6 TDCI (non-keyless entry) 125k miles. I'm hoping this a simple issue and I'm just missing something basic. The key fob for my car stopped working yesterday. None of the buttons do anything on the car. It was quite strange. I unlocked the car using the key fob button as usual after work, after a 20 min drive home, got out and went to lock the car with the key fob as usual and then just nothing... Tried opening it up and changing the battery to a brand new one, giving it a quick brushing, messing with the circuit board directly on the battery (checking if it was an issue with the contacts) and no luck. This is literally the first time I have ever had any issue with the key fob in the 3 years I've owned it. I've never even opened it before. I have not noticed any diminish in the operating range either which made me suspect the battery might be a red herring. Anyone have any ideas? Or suggestions to try?

pistolpete1 Posted February 20, 2019 Share Posted February 20, 2019 Hope your didn't try a replacement battery from Poundland or something? They only work with a decent battery. Saying that, I had same problem recently, and reprogrammed it to the car and all fine again. Quote Link to comment Share on other sites More sharing options...

They only work with a decent battery Yes it was a cheap battery from a euro shop. Not sure how this would make a difference in it not working at all? I could understand if it didn't last as long. 5 minutes ago, pistolpete1 said: Saying that, I had same problem recently, and reprogrammed it to the car and all fine again. How did you do this? was it a new key? Quote Link to comment Share on other sites More sharing options...

Just apply this and it should be be back to normal? If that is the case, i'll try this when I get home from work. Quote Link to comment Share on other sites More sharing options...

Worked on mine when the fob stopped working, and battery replacement made no difference. It wasn't a new key/fob, just applied that vid to my 'broken' key. I guess they can lose the programing for some reason? 1 Quote Link to comment Share on other sites More sharing options...
