Help- replacement ACU central locking

[TomGunter]

Hi everyone,
Just a quick ask for help!
Does anybody know anyone in the UK who is knowledgeable and can help diagnose an issue with a replacement ACU?
We had the original replaced and now the central locking doesn't work (we believe it isn't the key fob either).
We just need someone who can fix it as it's beyond our capabilities!

I would ask on https://www.boxa.net/forum/65-986/ as it is a UK forum.

Ah, thank you. I'll head there.
