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.

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:)

How can i stop my security light from coming on when i start my 2004 3.4 liter chevy impala ?


Hi Glenn, did you by chance replace your PCM with a used computer? If so you will need to have it reflashed, If not sounds to me like the Passkey security needs to be relearned. Also wondering why you replaced PCM after replacing EGR valve, Please if you can give me some more info on your veh. Body control module controls security so something is not right. Please get back to me, Thanks Randy.

2002 Chevy Impala wont start after letting sit after it warms up


Almost sound's like vapor lock , the fuel boils in the fuel injector rail , turns to vapor ! That was a common problem with carburetors , letting the vehicle hot soak after shutting down the vehicle an letting it sit for 10- 15 mins. The fuel would boil away ! Are the cooling fans working ? After turning off a hot engine the cooling fans can run on without the key being on , do you hear fans run ? What engine does your impala have ? 3.4 or 3.8 L . Has the check engine light come on ? The fuel pressure regulator could be leaking fuel . Pull the vacuum hose off the regulator after shut off the vehicle , is there fuel coming out of the regulator ? Dribbling out the end of the hose ? This could be bleeding the fuel from the fuel rail ! Good luck , hope i've given you something's to check that you haven't already .

Try starting the car, when the security light comes on, leave the ignition switch on for at least ten minutes then switch it off and repeat. On the third attempt to start , the system should be reprogramed.

How do i reset the security system on my 2003 chevy impala


Are you reffering to the alarm or the pass lock system that put the theft light on.....If its the alarm the put the key in the door and unlock it. If its the pass lock system put the key in the ignition and turn it on and try to start the vehicle. After it shuts itself off leave the key on for ten min until the theft light stops flashing the turn key off and try to start it again. This may take a few times....
