Part 12 looks to be labelled HF antenna. No idea where it will be though.

What it does question. It looks like the receiver aerial and unit for the remote central locking. Does your car have that as part of its specification, and if so does it work?

This unit will only be found on vehicles destined for outside Europe that use 315 MHz Remote frequency. You can see it says 315 MHz at the top of the screen.

If you are looking for the HF receiver its integrated into the Comms unit (the wiper & lighting stalk assembly).

In Europe we use almost exclusively 434 MHz remote with a few exceptions on Audi & BMW where you can sometimes fine 868 MHz remotes

Has the remote locking ever worked since you had the car?
You should be able to check live data to find out if the comms unit can 'see' the remote signal?

Where in the n/west (presumably the UK?) are you? There may be a forum member with diagnostic kit who might be able to help you.

I think you started the question wrong. Because you have a central locking system with a remote key that doesn't work. It's a job for a key coding technician. He should have a diagbox but also another device for encoding keys. First of all, he should establish why the remote locking does not work. Since every car manufacturer has a different system, the technician should know it.If you were to buy a real remote control key now, it would have to be programmed to your system.
