Safety is a critical consideration to a car owner. And they are not to be blamed because of the huge price tag on cars and also the high rate of car theft. Car thefts are no longer news and have been rampant for decades. However, the automobile industry has sought ways to tremendously decrease if not eliminate this constant vice in society. In the quest of doing this, the immobilizer technology was invented. In this article, we will be looking at what a car immobilizer is and how it works to protect your car from being stolen.
A car immobilizer was first patented in 1919 and was invented by St. George Evans and Edward Birkenbuel. It gained full popularity and usage in the 20th century when it was mandated for every car in Germany to have an immobilizer in 1988. Afterward, the United Kingdom, Finland, Australia, and Canada followed suit. Ever since then, the immobilizer industry has seen notable evolution that has improved car security.
A car immobilizer is a unit that prevents a car from starting if the right key fob or transponder key is not used. The ECU will activate the fuel engine and the ignition only when the right code is decrypted.
So, how does the car immobilizer do this?
Your keyfob transmits a set of encrypted data to your immobilizer. This transmitted data is encrypted and can be read only by a unique encryption key that is found in your car’s immobilizer. Once the encrypted data from your key fob is successfully decoded by the encryption key, your car’s immobilizers confirm that the encrypted data matches and start the car’s engine.
The car immobilizer automatically starts the car if you are using a keyless entry system, but for older cars, there will still be a need for a physical key.
Some advanced car immobilizers use "rolling codes" that change every time you start your car. Although these immobilizers still use a static code, the "rolling codes" is an extra layer of security to improve the security of your car’s immobilizer and lower the chances of your car getting stolen.
The question that you may be asking is ‘if car immobilizers were designed to stop car thefts, why is it not depreciating? Just like most security devices, there’s always a way to breach its effectiveness even if the chances are slim. Like we said earlier, car immobilizers make use of encrypted data, and this encryption is susceptible to hacking. Once hacked, your car can be stolen. Most researchers have hacked the most popular car immobilizers like the Keeloq, DST40, and Megamos Crypto. However, this doesn’t render car immobilizers useless. They still do a great job in protecting your car, and statistics have shown that car immobilizers have reduced car thefts by 40%. Besides, the automobile industry is working hard to refine and enhance the security of these immobilizers.
While you depend on your car immobilizers to protect your car from thefts, you also have to take precautionary steps to keep your car safe.
