Central Locking not working

The central locking on my Vectra is no longer working.

The key remote if fine because when pressing it, the car indicators light up
and I hear a clicking noise in each door (like the lock is trying to
engage), except no locking occurs.

If I try to lock by inserting the key in the door and locking, I get the
same result ie. a clicking noise in each door but no locking action.

It seems weird that a signal is obviously going to every door but no locking
occurs. Could it be a fault elsewhere (like the Vectra thinks a door is
still open, so will not engage the locks).

Any ideas on how to fix this?

 

check all the door switches.

Mine just did something very similar, I took off the right panel in the
right footwell, wriggled the connectors on the central locking control box,
and it now seems fine.

 

I had the same problem with locking
I suspected the small realys to be burned-out (I had a badly short-cut in the wire harness in the back of the car).
I changed the electronic module and now locking and unlocking is working fine.
I was quite lucky to find exactly the same part on auction - 1/5th the dealers cost.
I'm sure the relays can be exchanged, what I'm planning to do later.

central locking control box, and it now seems fine.

 

Did you have to reprogram the keys to a new control box? If so, how do you
do this?

 

I got sender with the unit.
Still planning to add next one, shall try with Tech-2
Very costly at authorised dealer, very reasonable at independent workshop.
