What is an immobilizer and how does it work?
An immobilizer is a vehicle security system designed to prevent thieves from hotwiring a car or driving it away without the owner’s permission. It works by using a transponder chip embedded in the vehicle’s key fob to communicate with a receiver in the car’s ignition system. When the key is inserted into the ignition and turned, the transponder chip sends a unique code to the receiver, which then checks the code against a stored list of authorized codes. If the codes match, the immobilizer allows the car to start.
The immobilizer system is usually integrated with the vehicle’s Engine Control Unit (ECU) and fuel system, which prevents the car from starting or running if the correct code is not received. This means that even if a thief manages to hotwire the car, the immobilizer will prevent the fuel system from functioning, making it impossible to drive the vehicle away. Modern immobilizers often use advanced encryption and rolling code technology to prevent hacking and unauthorized access. As a result, immobilizers have become a highly effective way to prevent car theft and protect vehicle owners from financial loss.
Can an immobilizer be bypassed or hacked?
