A Guide on Car Immobilizer Systems

Do you know what your car's immobilizer system does? Though you may remain uncertain about how specific parts of your car works, it is important to have foundational knowledge about your car's immobilizer system. That's why we have gathered as much information as we can with help of our orlando car locksmiths. Here's what we got.

What Is a Car Immobilizer System?

The immobilizer system protects your car from being stolen. This system is integrated into your car's engine block. If the right transponder key isn't introduced to the system, it stops your engine from running. This ensures that car thieves can't easily drive off with your car after breaking in. A few other notable things to understand about car immobilizer systems are:

1. Car immobilizers are automatically unlocked when you turn on your car.

Your car key has a digital code that your car's ECU will automatically read when you turn on the ignition. That means there's no separate step to unlock the immobilizer system.

2. Car immobilizer systems even work with keyless entry and turn-on features.

More and more cars have keyless entry and keyless ignition systems. Your key transmits the code over a short distance so your ECU's code processor can pick up the input as you keep your keys in your purse or set them in a cup holder.

3. Newer cars have even more advanced systems.

Today's car immobilizers often have two-part code systems. First, your key transmits a car-specific code that your car immobilizer system will automatically recognize. The second code changes each time you turn on your car. As your car recognizes the second code, it will automatically generate a replacement code and store it locally in your key.

4. Engine immobilizers are deterrents, not just preventative systems.

Potential car thieves recognize that new and smarter vehicles have more complex security systems (along with advanced detection systems). This recognition will make your car a less tempting target than older and less well-protected cars.

5. You can "reflash" your car immobilizer system if you lose your key.

If your key gets lost, an authorized dealer can help you replace it. They're the only ones who can reflash your car or deactivate the lost key and replace it with a new key and a new set of codes.
