How do you unlock rear door on transit van?

To unlock the rear door on a Transit van, you can either use the key fob if equipped, press the unlock button on the driver’s side door, or manually unlock it using the key in the lock cylinder located on the rear doors. If the van has a central locking system, make sure it’s activated for the rear doors to unlock simultaneously. For models with a manual lock, simply turn the lock mechanism to the unlocked position.
