Hi, my Mazda Demio's alarm goes off without any reason. It tends to be intermittent but once it starts it wont stop until we drive off and stop again. I did wonder if it was the car battery (starts first time everytime and all electrics great so I don't think it's this) or maybe a dodgy earth somewhere. However, I also found on a search that it could be the battery in my fob.

Any ideas and if it is the fob how do I change the battery without breaking the fob?

Thanks
