The Untold Story Behind GM Security Systems

Beware of the so called GM factory security systems or immobilizers, they hide behind many different names given by the auto industry to make them look more effective and advanced.

It’s not clear today whether those systems were really born with the innocent idea of preventing theft, or instead with the untold target of making money circulating faster. They systematically end up killing cars and often forcing their legitimate owners to give up their hopes and junk them just for that only reason. And it’s happening by the thousands… Every month!

VATS, PassKey, PassLock, Transponder, PK3 … and many others are the names they are given. They look all different, but they are not – they are based on the same simple principle that is way too easy for a security system. And all of them kill your car after she reaches the age of 7. And another thing in common they have: your dealer will ask you $1,000+ to fix them (so they can eventually break again…).

So why should you go to the dealer and not buy aftermarket or go to a small shop with a better price? It’s because those are “security systems” remember? And as such they can be treated only by authorized dealers…

So then, the luckiest of you might still think: “well, my car is worth much more than 1000$, I’ll go the GM dealer and just fix this Passkey system”… Not that easy! Do you know the greatest aspirations of any car maker in the world? Selling you a new car. And guess what? Most of those security systems have been discontinued by GM and cannot be fixed nor replaced.

What a strange combination of events…

And your car is still dead and will NEVER start anymore till you fix that darn thing that you cannot fix. So what do you do? You junk it. Then take a loan and buy another one for the joy of the dealer I mentioned above.

Get rid of those GM anti-theft systems! …Seriously! Bypass and remove GM VATS PassKey and PassLock systems even if you still don’t have problems with them. If your car is more than 6 years old, it is only a matter of time before the worst happens – and the problem is that you never know when it’s going to happen… and where! And it’s just too hard when it hits!

And this is how to disable security and save your car:

1999 Olds Aurora will not start. computer in dash not coming on, but all other systems (radio, lights, etc) come on. My mechanic (who I trust) says its the on board computer? Plus security system…. What is the difference and I still want to disable all security…. it only has 86000 old lady miles on it….. Thanks for any answer… John from Gaines ville, Fl..

Luke April 14, 2012 at 6:58 am

John, there are several computer in those cars, the main one being the ECM that regulates all the functions of the engine, but I believe your mechanic is referring to the Body Control Module (BCM) that also handles part of the security in your specific case, the other part being in the key/cylinder component. Our PRO Module would bypass the security system (factory immobilizer) and fix the no-start problem.

Luke: This sounds like it will work ol my 1995 Trans Am, but let me tell what happened and whatthe car does. It started about 3 months ago at a gas station I came out and car would not start but security light stayed on. Then after 3 minutes I could start the car. I figured the keyhole was dirty so I was told to shoot some wd40 in there with the extension stick in the can. This was after the car had been doing the nonstart on and off (sometimes start up okay) about 2 months. So I shot wd40 in the hole and it drove for a week with no problem then today it started the security light steady on for 3 min, then it would not start again. But now I got to work and the car will not start and the security light blinks on and off forever unless you turn the key off. So was the oil a fluke? Or will your Pro product work for me?

Reply

Luke April 1, 2012 at 7:32 pm

Jeff, the issue is what we try explain on our website, a little part of the immobilizer system is in the key/cylinder, but the brain is the Theft Deterrent Module (TDM) and both those parts have approximately the same lifespan. This you say is very typical, the cylinder’s part might have been giving up initially and now your problem is probably in the TDM. The NEWROCKIES PRO Module will bypass the system entirely leaving nothing in the loop. It will definitely fix this permanently.

I have a 2000 Grand Am. My problem started with the security light being and staying on. Then, it wouldn’t start the first time, wait 10 minutes and the car would start. Then sometimes it would start the first time, sometimes you had to wait. But then even if you get it started, the car will just quit on you in the middle of the highway. The first time it ran about an hour before shutting off. Now at soon as the car warms up, it will shut completely off. If you wait 15-20 minutes. It will start again (maybe). We thought we had fix the problem by doing something they recommended to bypass the security light. So it’ll start, but shuts off as soon as it is warm. Will your bypass system work for this? Also how easy is it to install since I am not very mechanically inclined? Thank you.

Luke March 27, 2012 at 4:34 pm

John, our NEWROCKIES PRO module is compatible with your vehicle and will bypass the security system permanently, but the problem you are mentioning is not only security, there is something else on top that need to be diagnosed apart, it could probably be the ECM or the crank sensor. If the issue is only security, the car would never die while running as the security system is active exclusively in the first 3 to 5 seconds after starting the car.

wade February 21, 2012 at 7:25 pm

Hi Luke, I have a 93 Bonneville that won’t start. I can jumper the starter but it starts and dies over and over. Might last a week and then start up. One thing I’ve noticed, when it’s starting, the security light comes on with the key, and goes out when it starts. When the no-start issue happens, there is no light at all. Everything I’ve read says the light will be blinking trouble. Could I have a faulty ignition switch (electrical part)? Not the cylinder. Tried that. Also noticed that the #1 fuse is dead while not starting, but hot when it will start. It goes directly to the ignition switch via a large yellow wire. Any thoughts? I’d buy your product, but I’m tired of parts-changing.

Reply

Luke February 23, 2012 at 6:49 pm

Wade, the fault, I would bet, is in the Theft Deterrent Module (TDM) that is the brain of the system. With our PRO module you will stop the part changing forever for this issue as it will bypass the entire security system, including the TDM, no exception, installation is very easy and if you are not happy for any reason you can return within 30 days and we will refund you in full – unconditionally. There is no risk, this is our big difference, and the fact that our PRO module is build with military grade components, so it will never fail for at least more than 20 years.

Tasha it is absolutely false. Any security system of any kind in any car is indeed bypass-able. Security systems are only marketing stuff to circulate money better and faster. Of course you would need a smart thief to steal it, not a kid, but i can assure you it can definitely be done.

I am working on a 2000 Chevy Impala. at first there was a ignition switch problem where the gauges would flicker when i jiggled the ignition”in the off position”. i replaced the switch and the flickering problem ended, now when the key is turned the gauges click twice and the security light comes on and cycles with the low fuel warning back and forth. there is no crank over nor do i hear the fuel pump pressure up. will the pro system start this car?

so could it be the security problem.the one thing that throws me off is the power windows and seats will not work when it wont start but in the morning everything works ok till it quits,than nothing just cranks over till I leave it sit for about an hour.please reply I am wondering if I should buy the bypass system.

Reply

Luke October 17, 2011 at 9:58 am

Bernie, this is not a security issue, can’t say anything, but I’m quite sure the PCM/ECM is the problem. I had the same on my 95 last year a swapped the ECM and all has been good till now. You can ask your mechanic to just try the swap, it’s a plug and play thing and he can unplug in 30 secs and return the ECM if that’s not the problem. Or you can even do it yourself getting an ECM at Napa, it’s extremely easy and a used one should run less than 100$.

Reply

Luke August 22, 2011 at 9:32 am

Looyd, it is indeed an indication of the security system failure. It usually starts with just the security light turning on and then it would randomly failing to start and get worse till it won’t start anymore. The process can take from about a month to a year and more. About the inspection, it depends on the laws in your state, you can ask to a licensed mechanic. Here where I am in Canada even a single light on or a PCM code would fail the inspection, but it can can be completely different in your place.

Luke,

Thank you for educating and informing the public on the ineffectiveness of certain OEM immobilizers. You reallly educated me on it also. I wasn’t aware of this problem on GM’s. You are right on one thing though. The name of the game is to sell another vehicle. However, car buyers are a fickle group. Once burned at GM or some other manufacturer, twice shy. Most people will go to Toyota after that type of experience with a consequent loss of market share for GM and the like. Some aftermarket immobilizers are very effective and better than their OEM cousins. The best in class immobilizers are ULC approved, and isolate multiple circuits on the vehicle. This renders the vehicle virtually theft proof. (With the exception of towing of course).

Steve Trent October 27, 2010 at 9:13 pm

I’m interested,my 99 Astro is showing signs of this. I don’t know if I’m capable of performing your fix myself, and I’d like at least a ballpark figure of what your part costs. Electrical stuff that involves much more than replacing batteries or bulbs confuses me. My keys don’t have an apparent resistor in them. They are the factory keys,with a thick gray/black cover on the top. My van was professionally converted by Gulfstream, when it was new,I don’t know if it’s an LS,BS,or BFD ;-) Can you tell me a bit more about what’s involved and what it costs? Soldering is not something I have mastered-plug-n-play is what I need. Thanks for your time.

Hello Steve,
I have a DIY version of the Full Bypass that can be found on
http://newrockies.ca/diy in the form of an eBook and a PRO “ready to
install” version that you can find on http://newrockies.ca/pro .
Both can be purchased directly from those pages on the website and
prices are there close to the “Buy Now” buttons, but in your case the
DIY is not compatible with your van as that year of Astro does not
have a “Fuel Enable” signal on the ECM.
The PRO version of the module will do work instead as it’s a
completely different design. In case of the PRO, price also includes
free technical support during installation.
