Central locking

[katelyndon]

Why does my central locking on my 2011 Transit keep unlocking. When I lock doors by key or fob they lock them unlock straight away. So I can't lock it at all. Help please

probably one of the doors isnt locking, probably an electrical fault . go to each door and check if it locking or making a noise when you press the lock on the fob. you will probably find the side door or rear door not working. dirty contacts on the side door sometimes, or even the side door runners broken ( will still slide but the little wheels break up) which makes the door drop where the contacts are. 

another area to look at is the rear door wiring where it hinges, the wires can break inside the plastic sheathing.

Thanks. I think it's the side loading door causing it

check the sliding hinges for play /damage to the runner

Thanks. I will check all that.  The dash light is always on, the one with the car saying a door is open. I do need a new sliding door so it could be that
