Ford Transit AMBULANCE central locking problem?

My ambulance is off the road because both cab doors do not close. When using the key I can hear the central locking working but nothing else is happening and the doors have to be held shut by being tied together from the inside. I need to fix this problem URGENTLY because the vehicke is needed over the Xmas period. PLEASE can anybody help!?

Have the same problem, my 2000 transit will not lock either. The doors close and it sounds like the doors lock, but then it unlocks again. If you turn the key the other way nothing happens.
Anyone have any idea how to fix this. I have been told to replace the control unit will cost $500

Not closing or not locking?
