Hi all, there seems to be a lot of small threads about the central locking not working with various outcomes. I'm going to try and get a thread together where any future problems can be solved by reading this one thread.

so my 05 UK convertible crossfire central locking won't work from the fob.

I get no flashing lights and lock and unlock do not work from the key.

the central locking button on the dash operates both doors, both locking and unlocking.

so far I have checked for water damage to the pump in the boot and it is dry and all locks work with the dash button so I'm happy it all works.

my fuse 9 is fine and all interior lights work ( common problem)

my alarm siren had a short and had melted the connector block so is now unplugged.

my thinking is now down to one of 3 things

1. key is not sending lock or unlock signal

2. Skreem is not receiving the unlock signal from the fob

3 The body control module is not getting a signal from the Skreem to send to the central locking pump to unlock/lock the doors.

so I'm thinking of a few options.

1.Getting a second hand kr55 key and moving the transponder chip and blade over and trying to sync it to the car.



2. Replacing the skreem. (can we use a second hand one?)

3.Replace the bcm ( can we use a second hand one)

4. replace key, drivers door lock, skreem and bcm from a breaker.

If we can all try and keep speculation to a minimum and just post actual experience it will hopefully make for a good sticky for the future.

and hopefully I will fix my central locking
