Recently my door has become jammed, it sounds like central locking is releasing but door does not open from handle inside or outside, any ideas how I can get the door open and what is the problem so I can fix it?
C5's are quite common for this. It will be the child lock. Where you turn the screw on the face of the door to activate it, will be half way between on and off. Only way to open it is take the door card off!
