with the key our lasses focus will not lock
it locks the car then immediately unlocks again
if i lock the drivers door manually with the door closed and then exit the car it will lock with the key
but then it will not allow the drivers door to open when the key is pressed
i was thinking it is the central locking actuator in the drivers door

ps by saying the key i mean the buttons on the original ford key

there is no aftermarket alarm system on this car

any help gratefully received
