How can I reset the remote key fob on my citroen c5 2005 hatchback. the method stated in the handbook - re putting key in ignition turning on and pressing lock button for approx. 10 secs until locks operate does not work. I have 2 remotes with good batteries. both stopped working at same time.
I have already got the information I required from a local auto-electrician.
Please close my question
Neither of your answers apply. The fault was the receiver in car going out of sync, and required battery to be disconnected for approx 10 secs and then reconnection. Both remotes then worked.
