Hello, my problem: the housing of the remote control is defective and the key no longer works properly. When I go to Citroen, I get a new FB (case and electronics), the key has to be re-fed and the whole thing still programmed. Price: outrageous! my solution: new housing (57 mm) with unfed key purchase at Ebay, old electronics clipping (transponder is on board) and mech. The mechanical key is clipped with a pen. Is it easy to get out and to use the new case? Thanks for a professional answer.
