- The engine immobilizer, an advanced anti-theft technology integrated into the ECT, stops the engine from starting without the vehicle’s genuine and authorized keys. An immobilizer uses a specially crafted, digitally-coded key—often referred to as a “Smart Key”—to accomplish that.
- These keys have a transponder chip inside of them that stores electronic security that is comparable to the vehicle’s password and can be read by a transponder reader. When a smart key is inserted, the immobilizer compares the security code on the chip with the embedded code on the ECU of the car. An engine immobilizer turned on the fuel system and the ignition circuit once a perfect match had been made.
- The ECU will not engage the gasoline system if the match is not the same, preventing criminals from starting your prized vehicle. Modern vehicles with keyless entry or engine start/stop functionality communicate a security code from the portable smart keys to the code processor inside the ECU, which then compares the two and enables the start/stop function to function.

Modern automobiles employ rolling/changing security codes in an advanced electronic engine immobilizer system. This system, which has two levels of security, is found in BMW vehicles. a constant personal code and a second code that changes. The mechanism updates the second code and stores it in the key each time the key starts the engine. Every time the driver turns the ignition on, the immobilizer first reads the personal code. It then asks for the second rolling code.
Only when both of these codes are correct does the immobilizer unlock the engine by sending another coded signal to the engine management system. The engine will not start without it. Even if someone tries to short the ignition circuit in the absence of the second security code, the engine will not start. As a result, it stops car theft.
