2002 chevy impala has security issue now car won't start
The security system has disabled car. I know this because I tricked it into
starting once. Now won't start again, can't trick it.
This is a very common problem on GM vehicles. Sometimes you can get lucky and relearn a new key. Most of the time it is deeper than that. There are ways to bypass this system now. I read through this page when i had my issue. Learned a lot. http://www.diy-gm-security.com/
