Hi 2015 C4 Picasso Grande One of the keys has just stopped working. I doesn't open the doors, and it cannot start the engine. When I push the start button with this key in the slot, it says "key not detected". I tried the reinitialisation procedure described in the manual, but it does not work.I also changed the battery in the key, but it was no different. The car has been at the garage recently, having had repairs to the fusebox and engine control unit, because of spurious warning lights. Any suggestions? best Barry |

You may need to re-pair your fob. This is how it used to be done. - Click Here - |

Thanks! Yes, I have been trying to do that (following the manual). The ignition is keyless, and when I insert the dead key into the fob slot, and press the start button, I get the message "key not detected". |
