Hi all I have just got a 2001 Lupo 1.4 Sorts and the drivers door has jammed shut. I locked it by turning the key 90 degrees to the left and the key jammed in that position. I managed to get the key back vertical and out of the lock but now it just spins. I have read up on what has caused this and the fix, but I can’t get started without I get the door open. I have the upper door panel off and I can see the mech spinning at the barrel without moving the solenoid or the connecting shaft. How can I open the door? Any help would be great. Regards Steve.
