I have a 9-5 SE 2000 that I just bought a little over a month ago and last Friday around 8pm my car alarm triggered for no reason. When I went outside to shut the alarm off with my remote key chain nothing happened, it kept going, rather loud I might add. It didn't matter how many times I locked or unlocked the car the siren kept wailing. When I put the key in the ignition she started but the alarm would stop. Again, I tried multiple times to shut it off with the electronic remote key chain to no avail. Finally after about five minutes later it randomly shut off. Since then I located the fuse for the alarm under the hood and removed it. I think this has solved the problem of alarm going off but it's also shut down the anti-theft system completely. I'm wondering if removing this fuse does any harm to the other electrical components and whether it shuts off the engine immobiliser in addition to the alarm? Now each time I start the car the SID display sends the CHECK THEFT SYSTEM. Advice?
you may not beleive this, but, your alarm systen, is radio controled. The little goody on your key ring is a tiny transmitter.It is on the same band as microwave ovens and cell phones. Some one in your neighborhood, may have been useing their cell fone, and it tripped your alarm. Don't worry about taking the fuse out. It will not hurt any thing. You may want to install a toggle switch under the dash, that will disable the alarm, in case it does it againreplace the flat battery in your key ring controler too.
