Not a major problem but does anyone know how to fix this? When I use the central locking button on the drivers door to lock the doors from inside they all lock except for the front passenger door  button, which needs to be pushed down separately.

Does it work on the key or outside door lock at all or is it totally dead?

Might be door lock motor. They are cheap second hand, but I'm afraid it's a pig to change.
