May need a autospark to check for faulty switch?? Part number will be usefull thanks.

I don't know if it's the same as with Volvos but on my Saab (when I had this problem) if I locked the car using the key manually (i.e. not using the lock button on the key fob) the alarm doesn't arm, so you can stop worrying about waking up your neighbours in the middle of the night.

Attached is the C70 removal / installation of the siren unit and part numbers for it. It looks like there's different part numbers depending on what sensors are fitted?

Thanks for the info and the pdf for the sirens
The key only use does work to lock the car which is ok for now.After speaking to a local specialist they think it may not be the siren but a switch that is faulty?it needs reading first so im not wasting cash.
