Ford transit lwb 55plate lock with remote then it unlocks its self.
Transit van side door wont lock.
This will lubricate the lock.
If not if its the same then there is usually a sticking sometimes faulty lock mechanism on the van.
All motors work on all doors as can hear them even clear the contact on the side sliding door still does the same locks then unlocks its self deker gough may 2020.
What happens is when it receives the lock signal because one of the locks wont fully lock as above it then kicks the locks open again as the system thinks there is a door not fully closed etc.
Then lock it all up as normal.
If your drivers side door won t open try spraying some wd 40 into the area where the door connects with the lock inside the car.
In my case i could have probably unhooked the yellow.
Try opening the rear door driver side and operate the inside handle.
This happened on a 10 plate transit last year more than once.
