The buttons on my remote control eventually let me go after 10 years. I could go to my Citroën dealership but beware of the note. Instead, I bought the shell less than 6 and I adapted the game with buttons on the other part of my old remote control. You just give light cutter strokes for a perfect fit because on my old remote control key is set and not screwed. The key to taking more space it takes a little digging hull with buttons. Result: it works very well
