Your Passlock may need to relearn the ignition keys, if the
ignition lock has gone bad like my in-laws Grand Am Gt, here is what i
did so they will not get stranded any more. Buy a Passlock by pass
module for around $70.00. You can order one from GMPASSLOCK.COM in the
mean time try resetting the Passlock. Good luck
Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure 1.) Turn ON the ignition, with the engine OFF. 2.) Attempt to start the engine, then release the key to ON; the vehicle will not start. 3.) Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4.) Turn OFF the ignition switch, and wait 5 seconds. 5.) Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock
Sensor Data Code and/or passwords on the next ignition switch turn from
OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle
learns the Passlock Sensor Data Code and/or password on the
next ignition switch transition from OFF to CRANK. You must turn the
ignition OFF before attempting to start the vehicle. 6.) Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7.) With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.
Without a scan tool you may have momentary starter interruptions while history clears itself.

I don't know how to hot wire it, if possible? I looked at your security system, it said passlock. The pass lock key is just a mechanical key, no pellet or transponder in the key. It's the tumbler that communicates with passlock system, not the key. Your local dealership might get you a new key for about 20 bucks, don't quote on that. A locksmith will make you a new key, I don't know how much they charge?
Where did you try to by-pass at , with the 2000 ohm resistor ? Is the SECURITY light lit on the instrument cluster ? Probably has another problem other then the key . The anti-theft system in your vehicle can not be by-passed by using a resistor .
The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
Your best bet , take it to a qualified repair shop . Before you render it unfixable . (cost to much )
You can't
The Passlock?"¢ sensor contains 2 hall effect sensors. The tamper hall effect sensor is on the top. The security hall effect sensor is under the tamper hall effect sensor. Both of the hall effect sensors monitor the magnet of the lock cylinder through an opening. The tamper hall effect sensor is physically placed on top of the security hall effect sensor. This arrangement enables the tamper hall effect sensor to engage first if an intruder attempts to bypass the Passlock?"¢ sensor by placing a large magnet around that area of the steering column. There is a tamper resistor inside the Passlock?"¢ sensor in order to help prevent tamper to the system. Passlock?"¢ equipped vehicles have a selection of 10 different security resistors ranging from 0.5K ohms up to 13.6K ohms. Installing one of the security resistors inside the Passlock?"¢ sensor will generate a unique Passlock?"¢ code. All 10 combinations of the Passlock?"¢ sensor have the same part number.
Ignition lock cylinder has a connector with three wires marked A-B-C , A is a yellow wire - signal to the BCM .
It sounds like you have an issue with your PassLock security system. I had the same with my 2002 Impala. Key turns OK, but won't start, won't crank. Wait 20-30 minutes, and car starts normally. There is usually a clue from the Battery and Security lights.
The problem starting to happen once a month, and eventually 1-2 times a week.
There are several write-ups on this problem for several GM cars for 2000-2006(?). Search this website, and search the web.
The official solution is to replace the ignition switch. The best solution is to bypass the Pass Lock system. I went ahead and did a full bypass, which involves cutting wires and adding resistors to the ignition circuit. I have not had a problem since.
Well, you wont be able to hotwire it direct. Thats why the Passlock is there. The TDM (theft deterrent module-also called Body control module- or computer) must receive and send the correct signal to let the injectors work. Thats why you car is shutting down. I dont know what you used as a BYPASS, but there is a really great one here that illiminates ALL parts of this system permanently. Read through this link and check out the PERMANENT FIX part. Sounds like this is what you need. Trust me on this one, you will NEVER be able to hotwire that thing, They are wound REALLY tight, and the Passlock system has its fingers in more than just the starter, it allows fuel doors to open, injectors to spray, and sometimes spark in general.
did you change the key? if you have it more than likely needs programmed as most of the gm's have either a resister based immobilizer or a passlock system. If its the same key check that you have all the connecters back at steering column as you may have disturbed the vat's one.
