Hey all. I've been having a problem with my 2000 Alero recently where, periodically, attempting to start the car will end in the car stalling and the security light beginning to flash on the dashboard. Usually after about 10 minutes the light goes off and the car starts normally (well, insofar as feeling like it's going to shake itself apart the moment it hits idle is normal, but that's another topic for another post). This happens about 40% of the time when starting the car, and seems to be happening more and more frequently (which may be my imagination).
I took the car into the dealer (after my local mechanic told me he was familiar with the problem and wouldn't be able to fix it), and they told me I needed to replace the body control module and passlock sensor to the tune of $1,042. The other dealer in town quoted me slightly better at $913. Has anyone else had these repairs done? Should they cost this much? Does it fix the problem? Any information would be greatly appreciated.
