Permanent GM Security Bypass · Since 2008

Does Your GM Start
Then Die
After 2 Seconds?

"In 2005 my Buick LeSabre left me stranded in my own driveway. I spent two days figuring out why — and built the permanent fix. It's now running in 32,000+ GM vehicles. If your car is doing what mine did, this is the fix."

SYMPTOMS

Does This Sound Familiar?

If one or more of these match your car, your factory security system is failing — not your starter or fuel pump.

Security light flashing on the dash

Car cranks but dies in 1–2 seconds

Must wait 10 minutes before retry

Happened suddenly after years of normal use

Mechanic says no fault codes

Resistor trick failed or stopped working

“I know that list because I lived every item on it. There is a permanent fix for this. I found it” —Luke

Why this happens

GM Security: What They Don't Tell You

The Principle

How GM Security Actually Works

The core of every GM security system is the engine immobilizer — sold as Passkey, VATS, or Passlock depending on the car. They all do the same thing, and they all run on one simple principle:

The Key & Lock send an input signal to the TDM through the wiring. If the TDM gets the right input, it produces an output signal to the PCM/ECM that lets the engine start. That's all it does.

NOTE: On some vehicles the TDM is embedded in other modules like BCM or EVO or even in the Instrument Panel Cluster.

Where things go wrong

A Very Expensive Problem

There are three things that can fail and each tends to last no more than 7 years, often much, much less. If even ONE part goes down, your car won't start, or it starts and dies within seconds.

Why the resistor trick fails

Resistor is a Partial Bypass

The resistor trick is just a key bypass, not a Passlock bypass. It only fakes the input signal — tricking the TDM into thinking the right key is in the lock. It's partial.

You're still stuck relying on the TDM: the brain of the system, the most complex and most vulnerable part. It's the time-bomb that, sooner or later, becomes the real cause of the no-start problem.

Why the PRO module works

NEWROCKIES is a Full Bypass

While GM obsessed over the input signal year after year, they didn't care about the output signal. No matter the make, model, or system type, that output signal stayed the same.

The NEWROCKIES PRO Module reproduces that exact output signal straight to the PCM/ECM — a FULL Passlock bypass that fires your injectors without VATS, Passkey, or Passlock system. You can disable, and often remove, the entire immobilizer for good.

The NEWROCKIES PRO Module works also when the TDM is inside BCM/EVO/IPC. And also when your vehicle doesn't start at all.

The peace of mind

Turn the Key and Just Drive — Like It Was Before

What if you could always start your car without ever wondering whether the engine would start?

  • No getting up earlier wondering if it’ll start.
  • No anxiety at the gas pump.
  • No more money drained into parts that never fix the problem.

Finally, there’s a complete, permanent solution to the no-start problem.

“I bought the ‘Resistor bypass’ kits myself. My car still died days later. Then came the parts-swapping game that empties wallets and junks good cars. I went down that road. Failed miserably. So I designed the PRO Module to bypass the system completely, once and forever.”

Questions & Answers

Luke Answers Your Questions

Same engineer who built the module — still answering email himself.

Is this really my problem?

On many GM/Isuzu vehicles, a steady or flashing security light usually means the factory immobilizer (Passkey/Passlock/VATS) is seeing a problem with the key, lock cylinder, wiring, or theft‑deterrent module and may start disabling the engine.

That’s often an early warning. The system is seeing intermittent faults but hasn’t fully locked you out yet. Most customers who ignore this phase eventually end up with random no‑starts or a complete no‑start.

That pattern is classic for an immobilizer fault: the engine starts, then the security system cuts fuel because it doesn’t see the “OK to run” signal from the Passkey/Passlock module.

Because the problem in your car is not the starter motor, but most probaIf the starter turns but the engine will not fire, and the security light is on or has a history of flashing, the immobilizer is a prime suspect. The PRO Module is designed specifically for this scenario.bly the Passlock system that failed. The NEWROCKIES PRO Module can bypass the Passlock permanently.

Yes. We see many vehicles where the internal module has failed without consistently turning the light on. Intermittent wiring issues or partial failures can still block the “OK to start” signal.

What is Passlock and why NEWROCKIES?

It’s GM’s factory engine immobilizer. Depending on the year/model it may be called Passkey, VATS, Passlock, etc., but they all work by checking a signal from the key/lock and then sending an “OK” signal to the engine computer to allow fuel.

A resistor “bypass” is a partial fix that only tricks the system into thinking the right key is present. It still relies on the original theft‑deterrent module to send the final “OK” signal, so when that module fails, the resistor trick stops working.

Because they leave the weakest, most failure‑prone part — the theft‑deterrent module — still in control. When that module finally fails, the car goes back to no‑start, even if a resistor or “bypass” was installed.

Instead of faking the input, the PRO Module recreates the output signal that tells the engine computer “all clear, allow fuel.” It takes the factory immobilizer out of the loop, providing a full bypass rather than a partial key trick.

Will this work on my vehicle and key type?

The PRO Module works on hundreds of GM and Isuzu cars, trucks and SUVs. To check if your vehicle is compatible, click <here>

Yes. Many supported vehicles use Passlock‑style sensors without a visible chip in the key. As long as your vehicle is on our compatibility list, the PRO Module is designed for it, with or without a visible chip.

Yes. The PRO Module is designed to work with VATS, Passkey (including 2 and 3), Passlock and Passlock 2, and all related GM immobilizer architectures on all the supported vehicles.

Yes. The PRO Module is specifically designed in a way that will fix your vehicle even if it's already in a no‑start condition. It will work even if your car doesn't start anymore.

Do I still need to replace other parts?

You do not need to replace the key, lock cylinder, or theft‑deterrent module just to use the PRO Module. The PRO Module lets you avoid all of those replacements.

If the problem is the factory immobilizer, then no, you do not need a new theft‑deterrent module (TDM) or BCM. The PRO Module is designed as a full bypass of the immobilizer function and, when installed correctly on a supported vehicle, it completely takes over the job of telling the engine it’s allowed to run.
In cases where the TDM is built into the BCM, EVO or IPC, you still don’t replace that module unless it has additional faults that affect other systems beyond the immobilizer circuit.

You can, but most customers come to us after spending significant money on keys, cylinders and modules that fail again. Our approach is to bypass the failure‑prone system entirely so it can’t strand you again.

How hard is installation?

Yes. the resistor trick guesses at a single value and bypasses only the KEY and the Lock. The PRO Module removes the entire degraded system in most vehicles and will work dynamically with the BCM/EVO/IPC/CCM on the others. If the problem is the immobilizer system, it will be fixed for good. Install it once, you're done.

Most installs take about an hour for someone comfortable working around basic automotive wiring. Typical tools are wire strippers/crimpers, a screwdriver, and a test light or meter. We provide vehicle‑specific instructions and wiring color codes for supported models.
Some vehicles may be more complex to work on, so it might take a bit more, but If you get stuck, just contact me and I typically answer emails the same day on working days (and often on weekends)

Many DIY owners install it successfully, even on their first wiring project. However, if you’re not comfortable working with wiring, we recommend having a local shop do the install. Over 1,200 shops in the US are familiar with the PRO Module.

The PRO Module is built with high‑spec components rated for extreme temperatures and designed to last the life of the vehicle. We back it with a 30‑day money‑back guarantee and lifetime replacement warranty.

Luke Lambruschini

The man behind NEWROCKIES

Luke is an electrical engineer from Canada. In 2005 his Buick LeSabre quit on him — same fuel‑cut, same 10‑minute lockout most of you are dealing with.

He didn’t accept the dealer bill. The resistor trick failed in 48hrs. So he traced the signals, understood the system, and engineered a module that bypasses everything: the key, the lock sensor and the weak Theft Deterrent Module.
Then he built a full bypass, not a half measure.

That prototype became the NEWROCKIES PRO Module. Refined over the years, today the PRO Module is installed in 32,000+ GM vehicles in North America and 1,200+ shops use it as their default fix.

If your GM is doing the same thing his did —starting then dying from security — you’re exactly who this module was built for.

I built this because I was stranded too. Every module that ships is exactly as I designed it. If you have any question before you order, contact me — I still answer. —Luke
