Question about 2005 Chevrolet Impala
If you have access to a diagnostic code reader, scan the vehicle anti theft system for codes and check component values. Look for signal interruption at key cylinder. That year impala does not use a resistor key but instead uses a sensor in the key cylinder that works off of movement rather than resistance. These cylinders are known to fail or wire damage at the cylinder. Remove steering column trim at key cylinder and inspect wires for breaks or chafing. There is also a known problem with the body control modules on these vehicles. Testing can be done through a diagnostic scan tool. I hope this helps you with your problem.
