SECURITY SYSTEM KEEPS SHUTTING THE CAR OFF. RESETTING THE SYSTEM DOESN'T HELP. HOW DO I BYPASS THE SECURITY SYSTEM

Ok I saw a Vedio on you too you can bypass the anti thief system radio shack sell the resister I think it a 3000 ohoms n bypass the key all you have to do is under the dash on the steering wheel is a yellow n a white wire those 2 wires r the security wire if you connect tithe end of on side of the resister n the other side of the rester to the white wire your bypassing the security system good luck

try restarting the car brain!!! Troubleshoot: disconnect battery and put it beside than wait for 30 seconds, take negative wire, positive wire from battery and hold them together for 20 seconds than retrive the steps and put things back together.

the system is either hooked to the battery or it has a fuse try disconnecting them

This is due to a failure in the antitheft system. The car doesnt get the correct signal from the key's CHIP, it takes this as a security threat and shuts down the car. This link may help you understand the problem.

If it doesn't turn over at all, it could be the crankshaft or camshaft sensor, is your security light staying on? If so, it could be your security system, passlock was installed in many gm's and caused alot of problems. Have your starter checked at autozone or advance, they check them for free. If it is the security system youtube shows how to bypass the passlock system. Also, check to see if your car is getting fuel. Hope this helps.

Is the security light illuminated in the dash cluster somewhere when you turn your key forward to start? If so, you have a problem with your passlock security system that comes on GM vehicles. Passlock works by shutting down your starter to prevent theft. Problem being that when its starts malfunctioning. it keeps owners from starting their vehicles. If that security light is on, read up on this info. If not, repost your problem so somebody else can help you. Im just telling you what i know. Im a wiz on these systems...

There are 3 parts in this system.
1.The CHIPKEY
Normally a black resister chip in key which "communicates" to the lock cylinder. Sometimes is hidden in the plastic part of keys in new models. Same concept, might say PK1 PK2 PK3 PL or something similar to that. The newer ones work on frequency. Same thing tho.
2.The LOCK CYLINDER
Inside there are pins that read the chip in the key or the part that reads the frequency on new models. This then "communicates" to the TDM)
3.The TDM
Theft Deterrant Module-Sometimes called the "computer" or "brain". This is the part that sends the signal (**NOTE**) to your car and allows your car to start or continue running depending on your type of system.
If any of these parts are not communicating properly, your SECURITY light will come on and shut down your vehicle. The idea being, that without the chipped key or FOB key, the vehicle wont start and cant be "hotwired" or stolen. Pretty nice when working, but these systems are flawed and the average life is 6-10 years. Every single aspect of this system is expensive to replace and can only be worked on by "authorized" GM service men with out voiding warrenty. Most garages dont even touch them and if they do,
they will sell you every part they can before "fixing" the problem/
*QUICK FIX TRICKS*
1st trick
Try a spare key that is newer or used less. The pins wear down with use and so do the keys causing the security to fail.

2nd trick
(if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my Buick for more than a year. If its shutting down while running, I'm sorry I have no quick fix...

*PERMINANT FIX*
Well since the lifespan of these systems are so short, and are extremely expensive to fix, and in my opinion far worse of a threat to owners than theives, my only perminant suggestion is to eliminate it completely. After a year of 10 minute tricks and a "key bypass" that lasted 2 months and stranded me out of state, ($375 tow charge) i have only one good suggestion. After surfing the web for hours thru forums and websites i came across http://newrockies.com/passkey to the starter or injectors and so on. Thus eliminating the ENTIRE system completely. I came upon a fork in my road. A TDM for $600 in my $1000 car or the $200 bypass. Or throw my car away. Lets say i now drive a Buick with the chip ripped out of the key and the TDM sitting in my glovebox for show
and tell. If you have any questions or anything else. Comment on this post
and i'll get an E-mail to reply to you. If you do choose to buy the bypass,
i have pictures of what a TDM looks like and will definately help you when
installing the newrockies bypass. Good luck
Here is a list of known effected cars that can be fixed with the
newrockies bypass. This is the same list from the site and updates
frequently.

thought I was the only one! I found it by accident... take the key out of ignition, open the back glass with key lift open then close glass back.... this resets the security system.....
my car did this 5 times, I would call for someone to jump me off thiking it was battery.... then when I got cables out it would start I finally realizes I was resetting sec, sytem//

You need to either replace the ignition lock cylinder or bypass the security system. If you need help with either one, repost.
