Central Locks

[willo]

at first my rear doors would not lock,replaced passenger side so far and now works, then the other day all 4 worked,tried it again now it doesnt and now drivers side front doesnt work.

all the doors will lock using key in drivers side lock but drivers door doesnt lock when using key in passenger side door lock,,when using remote the locks lock then open again on there own as if there is a door open.
