Disco 2 Central locking intermittently won't lock with fob, always unlocks

I've got an occasional problem with central locking. When it happens, the lock button on the key (either of two keys) won't work. I can reach in and lock with the button on the dash, then shut the drivers door and lock with the key.

Unlocking always works fine (with both keys). Once it's been parked up for a while, locking usually starts working again.

I've got a Nanocom, and when I checked it sometimes shows a 'door open' switch status when all are closed, so I guess that's why it won't lock sometimes, but there doesn't seem to be a way to see which door it is.

What's the easiest way to find the problem door?

As long as you have to lock with the dash switch and the driver's door doesnt lock too even if it's opened also if all the doors are closed and they dont lock all when you lock the driver's door with key the problem is within that actuator cos there is the main cdl monitoring switch too

Thanks, so is it an entire actuator assembly that needs replacing?

If the doors dont lock all when you lock the door with the key then yes
