V40 T4 Alarm Problem (1999 UK Spec).

Hi,

I have a problem with the above alarm (Volvo factory fitted). I
accidentally left a cooler plugged into the cigarette lighter all night
and it obviously drained the battery.

I jump started the car and drove for about two hours, and the battery
seems fine now (it's two months old).

However, when I lock the car using the remote the alarm goes off about 5
seconds later. This is not random, it does it every time.

I've checked the fuses and doors.

Any ideas?

TIA.

 

I've also noticed that the inside driver's door lock does not operate
the central locking, but both the dash button and the door key do!

Regards.
