Does your key have a small black chip at the base of the key if so it could be bad or the ignition could be bad it reads a resistance and if it is off by a few points it will think that the car is being stolen

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.

2001 chevy impala security light keeps coming on


This is a problem with chevy vehicles that have the system theft light. after a couple of years of using the key, the lock tumblers inside the ignition switch tend to wear out and so causing the system to think it's being stolen. Now you have to put the key in and turn the ignition to the on position, without cranking the car and leave it for 10 minutes until the theft light goes out. Very annoying especially if you're in a hurry. The dealer cost to repair the ignition switch goes for about $600-$800. that includes re-teaching the key.

My 2004 Impala won't start. Computer message is


try anoth igntion key, if not a good moble auto locksmith should be able to diag this, if he can't you'll need to tow it to your local GM dealership. It could be the igntion cylinder, but there is more items involved in the security system besides the igntion cylinder & you need the proper test equipment for testing.

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....

Ignition key won't turn


I'm not sure exactly what all the details are however, sometimes your steering wheel will turn after parking, just alittle enough to place some pressure on the lock. you might try turning the steering wheel and see if this doesn't take some pressure off the lock allowing it to turn. I hope this the problem and it helps.

Good luck,
