Central locking won't work with my key

I've been through 6 pages of searches for this and can't find a similar problem.

I don't have a key fob, just a key for my drivers door. The key turns the latch, which unlocks the door but there isn't any sort of mechanical noise, and it doesn't attempt to open any of the other doors.

I have taken the door card off the passenger door and the tailgate and they are all wired up (the actuator? is wired) and individually I can lock and unlock every door by pulling the latch up and down.

What can I do to make my central locking work again? I have taken this box out which I think is the control box? Also I don't have an alarm, and my red light infront of the speedo doesn't work, neither does the red light near the radio.

Any help appreciated as I'm sick of reaching over to open the doors now

There is info in the forum relating the micro switch at the rear of the drivers door lock and CL relay either may be faulty, so put the ECU back as you won't have an alarm, immobiliser or central locking with it disconnected,

Ok thanks so what can I test?

The black pump which the locks are attached too collapse on 2 of the doors. Is it more likely to be an electrical fault?
