My 2000 chevy impala security light came on while I was driving last night. It started today but then won't start now. This has happened 3 or 4 times before. I think it has something to do with the passlock but don't know how to fix the problem.

You may have to take it in to a Chevy service department and have them "reset" your P.C.M.
