In your BCM (Body Control Module) there is integrated a TDM (Theft Deterrent Module) that is probably faulty. I saved my car in the exact same situation with this: http://newrockies.com/vatsbypass . It was the only way. The author says it works with PassKey and VATS, but It works perfectly with Passlock too as the only difference between those 2 systems is that in PassKey the resistor is in the key, while in Passlock, the same resistor is in the lock ...that's where the names come from... :)

98 olds acheiva won't start, replaced starter and solenoid and tried the turn key on for 10 minutes then turn off and start, did not work I see no chip in my key but security light stays on and car...


If the security light is on, then it can only be one thing. The security system is failing and immobilizing your car. Go to this link and read up on the problem. The security light is a dead give away that the security is messed up. If you have no little black chip in the shaft of your key, then this means you must have a passlock that runs on the transponder. You need the PERMANENT fix from this site. http://vatspasslockpasskeysecurityhelp.yolasite.com/

The car fires but stops immediately


I had a problem with a 97 Achieva recently.Someone else replaced the PCM/ignition switch and passlock sensor.I replaced the ICP.Engine would turn over but wouldn't start and the security lamp was dim and flashing and then it would go solid.I tried the wait 10 minutes thing but,the light would never go off! I put the original passlock sensor back onto the lock cylinder. But this is what fixed the problem.I cleaned the contacts on the black wires and green on the ignition switch with tv tuner cleaner! After I cleaned those contacts the security light was flashing brightly.So I turned the key to run and left it there.After a few minutes it stayed on solid.I waited about 10 minutes but the light never went out.So I turned off the switch and then tried starting.It started right up and the security lamp flashed and then went off.Has started every time since.Note:I also scraped the pins that I cleaned with the cleaner with a knife.

My son has a 1999 grand am, just like the oneshown above. the car wont start because the security sys. shuts off the fuel sys. down. the manifold still has good pressure cause we just had thefuel pump...


Need a bit more information, Is the security light on, have you checked for spark and fuel pressure2.gif, just in case you did and know it is the passlock system then check this out, hopefully it will ansewer your problem, please rate your mechanics help.
have a great day. Sorry the pictures won't come up, but check out the site
GM Passlock I & II Information

Please study the following information carefully WHEN INSTALLING REMOTE START systems on a 1996 or later GM car or truck.
Introduced in 1996, GM has changed the VATS anti theft system to Pass-Lock system. This is a similar device to the VATS system, in that there is a resistor present2.gif during the start cycle. However, in the PASSLOCK system, the resistor has been placed inside the ignition switch, instead of the key. See the GM V.A.T.S page for more information.
To remotely start a car with this feature, you must bypass the PASSLOCK system. There are two methods of doing so.. The first, is to permanently bypass this system. This is the easiest method for accomplishing your task. The second way, is to temporarily bypass the PASSLOCK, by introducing relays into the system, which retain all of the features of the system, while allowing your remotes start module to bypass it automatically during a remote start cycle.
Vehicles effected
(1996 and newer): N & J body cars, such as
Pontiac Sunfire and GrandAm Passlock-1
Chevrolet2.gif Cavalier Passlock-1
Buick Skylark Passlock-1
Oldsmobile Achieva Passlock-1
1997 or newer
Chevrolet Malibu2.gif Passlock-II
Oldsmobile Cutlass Passlock-II
1998 or newer
All trucks , SUVs and Vans Passlock-II
It is important to pay special attention to the fact that there are many different ways of achieving the same goal. There are actually 2 different Passlock-II systems. On the next page, there are tests to establish which type of passlock-II your car has.
Relays shown are standard automotive 5 pin spdt relays, available from IEI.
A multi meter is required to measure the resistance values. Accuracy is important within 5%.
Once the value of the resistor is measured, a resistor of the samevalue +/-5% must be purchased (Radio Shack2.gif, for example). You can also use a Potentiometer (POT), which can be adjusted to the same value of the resistor in the ignition switch.

pslc1.gif Passlock-I bypass procedure....

1: Remove the top and bottom shrouds from the steering column.
2: Find the 3 wire ribbon cable2.gif, coming from the ignition switch, containing White, Black, Yellow (Sometimes White, Black, Black). These are THIN wires.
3: Locate the Black 6 position connector on the LEFT side of the steering column, right above the ignition switch position. There is a BLACK (Thin) wire in this connector, called "Bulb Test", which shows Ground with ignition in the Off position, OPEN in the "Run" position, and GROUND in the "Crank" position.
4: Turn the ignition switch to the "Run" position. Do not crank the car.
5: Cut the Thin Yellow wire and strip both ends.
6: Without cutting the Black wire, expose some of the copper.
7: Using the ohmmeter, measure from the Yellow wire (the end coming from the ignition switch), to the exposed Black wire and record the value. Measure more than once to assure you have the right value.
8: Acquire the same size resistor and 3 relays, and perform the connections shown in the diagram below.

pslk2.gif PASSLOCK-II bypass procedure

There are 2 types of Passlock-II systems. To determine which system you have, follow these instructions;

1: Locate two wires, which are THIN and are in the main ignition harness.. Orange/Black (or Black) and Yellow.
2: Cut the Yellow wire, and strip back some of the insulation from the Orange/Black (Or Black) wires.
3: Turn the ignition to the "Run" position ( don't crank the starter). Measure and record the value measured from the KEY SIDE of the Yellow wire, to the Black/Orange wire.
4: Turn the key to the "Crank" position and release. Now read the value again.
pslk3.gif5: If the value changed, follow "Method#1". If the value stayed the same, follow "Method#2".

I need to reset the security system but dont have


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. Good luck and hope this helps, keep me posted, be glad to help.

Security light flashing and car won't start now


does it start at all, or does it run for about 1 second and shut off? if the latter, then it's the passlock system, and he could have a defective key or security module. the keys have a predetermined resistance value which activates the passlock system to prevent hotwiring. If it is the passlock system, then sometimes you have to wait 15-20 mins for it to reset before starting the engine.

Starts but then it shuts off


Make sure those 3 wires on the passlock sensor are good.That sensor is on the lock cylinder on the right side of the steering column. You may want to check the wires on the ignition switch also.(green,black).But I would look at the sensor 1st since that is where they hook up those remote starters as far as I know.
