i10 alarm and key fob issue

Hi.
I have a i10 2013 model.
The battery went flat a week ago and it was charged and started the car up.
But since then both the key fobs have stopped working. The key fob batteries are both ok.
Also I noticed the factory fitted car alarm doesn't work anymore, I have tested it by locking the car and opening the door from the inside and it doesn't arm, nor does it go off
Another thing is that the electrics can all be operated, even when the car keys are taken out of the ignition. I sat in the car for 30 minutes and they still operated.
I'm talking about the rear heater, the blower fan, the windows, the AC, the radio, all the electrics still operate, I know it didn't always do this because the rear heater, the blower, the AC all used to go off when I took the keys out.
I'm thinking it might be a fuse for the alarm or a relay.
I want to check these before I go to a garage.
Anyone have any idea which fuse or relay controls the car alarm.

Any help appreciated..

Thanks in advance
