Chevy Cruze Won't Start Anti Theft - (Easy solutions)

What Causes Chevy Cruze Anti Theft Immobilization Problem

Chevy Cruze comes installed with the automated electronic theft-deterrent system that’s programmed to prevent stealing in several steps. And offers a great range of aftermarket car alarms for older models.

If you’re wondering why Chevy Cruze is getting so uptight about its anti-theft system, you should know that Chevy is one of the most stolen vehicles out there.

The theft-deterrent system is constructed of sensors and a responder module. The sensors are placed on several parts of the car to ensure the utmost safety from physical contact. The reason why even the slightest bump can make the system think the vehicle is in the wrong hands.

When the sensors don’t recognize the authority figure, it primarily responds with the rapid flashing of the anti-theft light and the constant beeping of the car alarm. A warning on the screen appears; and finally, the system immobilizes the engine to make it impossible to start the car.

While it sounds extreme in theory, pretty effective to stop a thief from approaching from any direction.

However, to predict any possible move, the system is too intertwined to mistake a simple thing for a cautious activity. It can even be caused by the fact that the battery is too low for the engine to function.

So yeah, you can come and find your car all immobilized for various reasons. The question is,

How to start the Chevy Cruze when a thief-deterrent lock won’t let you?

You can try to get out of this mess using some simple tricks.

#1- Unlock and Lock the Door:

Unlock the car door by pressing the unlock button key. Get out of the car. Activate the lock and now close the door. This will reset the system and mobilize the engine.

Try it again several times if didn’t succeed on the first attempt.

#1- Use a Spare Key:

Since this can happen anytime, you should always have a spare key with you. In fact, an owner should always have a backup for their keys, as they’re easy to lose.

If the “spare” key happens to be the original one, there’s a good chance it’ll deactivate the lock. Or it can be the cut that might do the trick.

#1- Rest and Don’t Twist:

Try resting the key instead of twisting it. Enter the key into the ignition switch and remove it after 5-10 seconds. Repeat this process a few times and the warning will disappear and you’ll be able to unlock the ignition.

In case the primary issue is in the ignition chamber, start the ignition and wait for ten minutes, and then turn it off. Start the ignition again after some seconds, and the lock might reset.

These are the first go-to methods people go for to start the engine, and most of the time it works if the system’s alright.

Sometimes, the system goes into locking mode due to low battery. In that scenario, all you have to do is charge the battery to start the engine.

However, if none of the tricks help mobilize the engine, you may have to manually reset the anti-theft system. Which might be the initial step with the older models.

Before reconnecting, make sure the system isn’t active in any way. Wait a few seconds if the light is flashing or the alarm is going off.

Now reattach the cables. This time, start with the positive wire.

3. Check the System:

Check the system by pressing the “start engine” button, or the start button on the key fob. The car should start now.
