Hi,
I'm like a girl when it comes to my car (;
I have no idea what sort of alarm I have on my car, I just press the beeper twice to turn it on and once to turn it off. It could easily be something to do with it. I discovered another new difficulty in that when I open the car in the morning, place child or luggage into the car, it will lock itself without warning. This is not a feature with the car, but again only seems to happen in the cold.
Regards,
