If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will then be deactivated and the engine will be able to start.

The key that is equipped with a transponder chip can be referred to as a 'fob' or a 'smart' key because it is much more difficult to copy than a conventional mechanical key. It is possible to duplicate a traditional key, but not a transponder one. Contrary to the remote key fob repair near me - click to investigate, central locking element of a conventional key that relies on battery power, a transponder chip is powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

The chip then responds with an individual code to the immobiliser inside your car. The car's computer examines the code in its memory with the one on the transponder and If the two codes are identical, it will start the engine.

This can be due to interference or an immobiliser that is too sensitive. If this is the case, it may need to be reset. To do this, simply disconnect the battery. Leave it disconnected for about 15 minutes, then insert it and begin the car. This will reset the system and allow it to accept the key again.

Modern cars are fitted with this security system in the standard configuration. This makes it very difficult to hot-wire a vehicle or utilize a different key for starter. The system works by checking the chip in the key fob or a key and sending a passcode back to the ECU (electronic control unit). The ECU then knows that it's the right key and that the passcode isn't compromised. The system will not allow the car to begin in the event that it does not receive the correct code. Some models even inform the owner when they attempt to use an unapproved fob or key.

The system isn't completely 100% secure, however. Some thieves have gotten around the immobiliser by using techniques such as 'hot wiring.' This involves crossing the wrong wiring in an automobile to fool the ECU. This is a risky method and requires extensive knowledge to avoid electrocuting oneself.
