Reset passlock code - Impala Chevrolet Cars & Trucks

Is your Impala a 2000, 2001, or 2002? This seems to be a common problem in those model years...much like its predecessor the GM VATS (Vehicle Anti-Theft System). While the VATS had a permanent (albeit unapproved) solution, no suck workaround appears to be available for the Passlock system. Some websites offer a correction "module" that looks to be a hit-or-miss solution. I did find the following procedure on a forum, and it seems to be reliable. Here goes:
If your car has been sitting while you were at work or home or in the store, and you are coming out to leave, follow steps 1-6.

If you just had the SECURITY SYSTEM lock you out of the ignition system, you will have to wait the 10 minutes for it to reset and allow the ignition control module to interact with the system. Once the 10 minutes have passed from the ACTIVE SECURITY STATUS, follow steps 1-6. Do not try to shortcut this as it wont work.

If it is raining, you can close your door, just not all the way. Close it all the way and open the door latch without pushing the door open. This will keep you dry.

+++++STEPS+++++ 1.) OPEN YOUR DRIVERS DOOR AND SIT DOWN. 2.) PLACE KEY IN IGNITION, WAIT FOR CHIME. (3 seconds is what I usually wait) 3.) TURN IGNITION 1 CLICK RIGHT (TO THE ACC POSITION) AND STOP! Do not continue to ON and START yet. WAIT ATLEAST 5 SECONDS 4.) AFTER 5 seconds has passed, TURN KEY TO ON and STOP, DO NOT CONTINUE TO START YET! 5.) WAIT AND WATCH. With your drivers door open, here is what you will see and hear = Your notification will signal DOOR ADJAR, then the BATTERY light, then the SECURITY light, during which you will hear the chime sound as if you just started the car. 6.) AFTER YOU SEE THE SECURITY light switch back to DOOR ADJAR or Battery, and after the CHIME has stopped, you can turn the key to start and voila!

It has worked every time for me and 5 of my friends. This whole process takes about 20-30 seconds, but it sure as hell beats 30 minutes, as GM refuses to compensate my time lost to their vehicle\'s design flaws.

RECAP: 1.) Open driver door, sit down 2.) Insert key in ignition, wait for chime 3.) Once chime starts wait 3 seconds 4.) Turn key to ACC position WAIT atleast 5 seconds 5.) After 5 seconds turn key to the ON postion and wait for the security light to switch back to Battery or DOOR adjar, and the chime to stop (Do not try to START if the chime is still sounding) 6.) Once chime stops and Security light has passed, You may now complete the turn to START and it will start.

Note: This is not a permanent workaround, but it will buy you some time, I can almost guarantee it will work for most if not all people, almost all the time.
