The system examines the code to make sure it's correct. If it's not then the system will disable components crucial to starting the vehicle, like the starter motor or ignition.

Most times, a faulty immobiliser is the result of an inactive or dead key fob battery. This can be confirmed with an instant diagnostic test. If the problem persists, then there might be other causes of the car's misbehaviour, including electrical issues or a wiring problem.

Transponder Chip
A small electronic chip, also known as transponder, is embedded in the head of your car keys. The technology was introduced in cars made after 1995. Also known as a chip key or a 'transmitter & responder' key, it is designed to stop the engine from starting if a third party has an exact copy of your car key. It functions by sending a radio frequency signal from the key to the immobiliser system inside your car. If the code in the car's computer is in line with the signal from the key, it will disable the immobiliser and allow the engine to begin.
The key that has the transponder chip can be referred to as a 'fob' or a 'smart' key due to the fact that it is more difficult to clone than a conventional mechanical key. It is possible to duplicate a standard key, but not a transponder one. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder the ignition cylinder needs to be in the ON position. The ring emits IR energy which is picked up by a microchip inside the key. The chip then sends an individual code to the immobiliser inside your car. The car's computer checks the code in its memory with that from the transponder chip and If they are compatible the engine will be able to start.
The immobiliser will shut down the engine when it detects an unauthorised transponder or key. It also blocks all vital parts of the car from functioning. Without a functioning engine the vehicle will not be able to move, and it could be easy for criminals to connect the vehicle to a hot wire and drive away.

If the system can't identify a digital serial number from the chip in your key it will more info disengage the engine immobiliser and stop the car from getting started.
The car immobiliser is a fantastic method to deter thieves, but it could sometimes be out of in sync. This can be due to interference or the system is too check here sensitive. If this is the case it could be necessary to reset. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes, then insert it and begin the car. This will reset the system and allow it to accept the key again.
The security light is a way of warning you of a problem. If the light is on when you try to start your car, it is a sign that the code in the ECU is not compatible with the chip on the key. This could happen if have recently replaced your car key with a different one that isn't programmed to the vehicle or if you've had a bad swapped ECU.
If this is the case, then it's time to talk to a professional to have the key or the transponder chip properly programmed to your vehicle.

Modern cars are fitted with this security system by default. This makes website it extremely difficult to wire a car or use a different key for starter. The system works by sending a code from the key fob to the more info ECU. The ECU is then able to determine that it's the right key and that the passcode isn't compromised. The system won't allow the car to start if it doesn't receive the correct code, and some models will even notify the owner in the event that someone attempts to use an incorrect key or fob.
The system isn't impervious to attack, but it is. Some thieves have managed to bypass the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wires within a vehicle's wiring to fool the ECU to believe that the correct key or fob is being used. This is a risky method and requires a lot of knowledge to avoid electrocuting oneself. In addition, many modern car thieves have shifted to more sophisticated methods such as using specialised apps or Bluetooth to hijack the car's information and remotely control it using their phones.
Car owners will often get warning lights that indicate that the immobiliser has gone off the rails. This could be due to a variety of reasons, but one of the most frequent causes is due to a damaged or dead battery on the key fob. A simple replacement can fix the issue.
