Cheers guys.
I managed to get it sorted, Anthony got in touch really quickly, i was pleasantly surprised as it’s Christmas Eve.
It ended up being the car battery, it got probably got drained due to the cold and the fact that it hadn’t been driven since Tuesday. Jumped it and went for a long drive, seems to be ok now, alarm arms but locking doesn’t so need to use the oem fob to do it. I’ll get that sorted after the new year.
I have multiple layers of security, but I guess if someone wants it that much they’ll probably come into the house to get it.
The fob I have is the lcd one, so I can charge it via USB.
Anyway glad I got it somewhat sorted!
Merry Christmas again all.
