    I just had this problem diagnosed on my 2002 Impala at a dealer. He couldn't find out what it was until he drove it 28 miles. It is either poor connections to the Body Control Module (BCM) or the BCM shorted internally, which he said mine was. cost to change out.$337

How can I bypass the security code


Why do think the key security is bad? If you still have a factory key, this is not the problem...if no factory key, you can take your VIN number or original key to GM dealer to get new key that they will program for you...Check for dirty battery connections:)

2002 chevy impala won't start if I jump starter


Is the security light on or flashing ?
The yellow wire goes from the key switch to the neutral safety switch, then to the starter. So bypassing the neutral safety would make the starter crank the engine, but would have nothing to do with the rest of the engine.

My 2005 chevy impala won't start since someone broke into my car


i would say when the person broke into your car they set off the security system which stops the car from starting, the way to reset the security is to put your key into the ignition turn the key until all the dash lights come on and let them stay on about 15 minutes after the 15 minutes have expired turn the key off and wait about 3 seconds and then your car should start. hope this helps.
