If the code stored in the computer of the car matches the signal sent by the key the immobiliser will then be deactivated and the engine will begin to run.
The key with the transponder chip is sometimes called"fob" or a "smart" key because it is more difficult to copy than a traditional mechanical key. Utilizing specific techniques, it is possible to copy a standard car key but not transponder keys. Contrary to the central locking element remote of a conventional key that relies on battery power, a transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder, the ignition cylinder must be in the ON position. The ring emits a blast of IR energy, which is detected by the microchip in the key. The chip responds with an individual code to the immobiliser of your car. The computer in the car analyzes the code stored in its memory to the transponder's and when the two codes match, it will start the engine.
The immobiliser will shut down the engine when it detects an unauthorised key read more or transponder. It also blocks any essential components of the car from working.

That's why it's difficult to beat.
Modern cars have this system as standard. This makes it very difficult to hot-wire a vehicle or use a different key as a starter. The system works by sending a code from the key fob to the ECU. The ECU is then able to determine that it's the correct key and that the passcode isn't compromised. The system won't permit the car to start if the doesn't receive the correct code, and some models will even report back to the owner if someone tries check here to use an unapproved key or fob.
