Hi I have a problem and need some help please!

When the weather is cold the immobiliser kicks in and i cannot start the car. I am sure that it is cold related as the problem started about 6 weeks ago when it started getting colder. I have had it into the garage and the only suggestion was to get the immobiliser removed.

Any suggestion ??

Thanks

If it's just temperature that seems cause it could it be the fob battery?

Otherwise damp air causing a contact or circuit problem. 

I had a problematic cobra alarm system fitted to my 94 sti , had a mobile alarm fitter fit a thatcham category alarm for just under £300 .

Not sure if the later models are as easy to remove the existing imobilizer and replace though
