Understanding Immobilizers: Your Car’s Security System
An immobilizer is like a guardian for your car. It’s a fancy way of saying your car has a built-in security system to keep it safe from thieves. This system works by ensuring only the correct key can start your vehicle.
How does it work?
Inside the key you use for your car, there’s a tiny chip called a transponder. This chip holds a secret code. When you put your key in your vehicle, the chip sends this code to the car’s computer. Then, the computer checks if the code matches the one it knows. If they match, your car starts. If they don’t, your car won’t start.
If someone stole your car, what would happen?”
If someone tries to start your car without the correct key, the immobilizer system can sound an alarm to alert you. This is different from a regular car alarm that simply makes noise. The immobilizer prevents the thief from being able to drive your car away.
