How It Works In Toyota Corolla
The Toyota Corolla uses an immobilizer system. It checks for a special code in the car key. The key has a small chip inside it. When you insert the key, the system reads the chip’s code. If the code matches, the engine starts.
If the code does not match, the engine will not start. The system blocks the fuel pump or ignition. This makes it impossible to drive the car without the right key. The system turns on automatically each time the car is locked.
