I can't open my doors with the fob or tuching the door handles on my C4 Picasso (2015). I have replaced the battery and ensured the connectors are touching both the underside and the side of the battery (also on the spare fob). I have to use the "integral key" to open & look the drivers door. And the car start and turns off OK. Can someone pls suggest what else I can try and do. Thanks in advance! |

Change the CR2032 cell in the fob. Don't squash the two edge contacts down when refitting the new cell. Here's how to do it : - Click Here - |

Note that the battery does not affect starting the car. The little chip that interacts with the immboiliser does not reqwuire power. | ||

Thanks for your reply wunny. As I said: "I have replaced the battery and ensured the connectors are touching both the underside and the side of the battery (also on the spare fob)." Any other ideas? To "routemaster" - Can you pls suggest what else I can try and do. |
