My car would start, drive some 35 miles, and after a wait of an hour, wouldn’t start again. The battery was replaced and the next day, same problem. The alternator and starter test fine and I am told that the problem is in the “computer” - the security system is telling the auto lockup to occur. The red security light on the dashboard does come on after driving a short distance. I am told the “computer” will cost about $1100. Does this sound like the probable cause and a reasonable cost to repair?
No, Not The Probable Cause.
What Make, Model, Model-Year, Is This Vehicle ?
How Many Miles On It ?
Who Told You That You Need A Computer ?
Year, make, model?
It could be reasonable. Just agree ahead of time what the shop will do if the replacement part doesn’t fix the problem.
If it does turn out to be a faulty ECM, then you might want to consider a rebuilt rather than new. Rebuilt will cost less and is likely to be better than new as most of the electronic components will be burned in to a greater extent than new components.
I had a 1980s ECM failure. New as I recall was around $700; rebuilt was around $300 or $400.

Since very similar problems occour with the GM Passlock II system an entire industry revolves around by-passing Passlock II. Have you “googled” "How can I by-pass the (good time to find out the exact name of your system)on my 2000 Sebring? Perhaps the same type equipment exists for your Sebring.
