Your Renault kangoo side door will not unlock is it interlocked in some way mabe with the filler cap it used to click when you unlocked the filler cap now it dosn'NT?

The kangoo has a safety feature built in that locks the n/s sliding door when the petrol cap is removed, otherwise the door overlaps the petrol tank filler when opened.
The system uses a small magnet in the side of the petrol cap assembly to trigger a reed switch that then operates the locking unit.
The presence of the magnet keeps the switch open and prevents the door from locking and when removed locks the door.
My first course of action would be to make sure that the magnet is still there, it should attract an iron object. Then check fuses etc.
Hope that helped. The kangoo has a safety feature built in that locks the n/s sliding door when the petrol cap is removed, otherwise the door overlaps the petrol tank filler when opened.
