Does the key still pop the trunk/hatch? That would also indicate whether or not it was the key remote. If that function works it's probably nothing on the car (i.e. "receiver") end.

There is a very good SAAB forum that would likely be the best place to find out if somebody has has this issue before and what they have done: www.saabcentral.com

SOURCE: Alarm haywire, can't override anti-theft system or turn on car

The Alarm on my Mercedes ML320 sounded every night, then it started doing it more often, Showed it to the dealer he says it's the 'Tow Sensor', that needs to be repaced. $700, down the drain. I have already started hating this car, it eats $500-600, every 6 months...

SOURCE: Automatic door locks will not work.

you need to take it to the dealer and have them check the bcm for codes.... also have them check to be sure you have the latest software in the bcm.. its possible that you just need a software update... there are several TSB's covering the concern you have..... it can be a very simple fix with software or even a stuck lock switch may need to be replaced... without the proper diagnostic codes being read from the bcm all that can be done is guessing..and that can be expensive...

SOURCE: I do I reset the alarm/door locking system

there could be a problem with the actual remote, get it checked, if you do need a remote plz get it from a mercedes main dealer.

SOURCE: key will not go into ignition, drivers door lock stopped working

I had the problem with key not going into the ignition on 2005.5 Jetta had to have the car towed and ignition replaced which cost 375$. But what i read afterwards is there is a locking mechanism in the ignition it is a white thing that slides so you cant get your key in this can be moved with a a small aharp object ant you can then get your key in!!!
