This chip transmits a code to the immobilizer unit of the car which can be integrated into the PCM, BCM, the instrument cluster smart junction box, or standalone module.

Transponder Chip
In vehicles manufactured after 1995, a tiny electronic chip called transponder is embedded in the head of your car key. Also referred to as a 'chip key or a 'transmitter and responder key, it's designed to stop the engine from starting if someone else has a copy of your car key. It works by sending a radio frequency from the key to your immobiliser system. If the code stored in the computer of the car matches the signal sent by the key, the immobiliser will be disarmed and the engine will be able to start.
The key with the transponder can also be referred to as a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than a mechanical key. Utilizing special techniques, it is feasible to copy a conventional car key however, not a transponder key. Unlike the remote central locking element of a conventional key, which is powered by batteries the transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits a burst of IR energy which is picked up by the microchip in the key. The chip responds by transmitting a unique code to the immobiliser in your car. The car's computer compared the code stored in its memory to the one from the transponder chip and when they match the engine will begin to rev.
If the immobiliser detects an unauthorized transponder or key is being used it will shut down the engine and stop the essential components from functioning. The car won't move when the engine isn't working. It's easy for a criminal to hot-wire it and drive off.

If you do not take action, the security light on your car will keep blinking, and you won't be able to begin it.
Security Light
The immobiliser is powered by a tiny battery that transmits an electrical signal to the transponder chip in your key. This anti-theft device stops anyone from starting the car without the correct keys. If the system cannot detect a serial number digital from the chip inside your key, it will deactivate the engine immobiliser, preventing the car from getting started.
This system for car immobilisation is an effective in stopping thieves but sometimes it can be out of connection with the key or the transponder chip. This could be due interference or an immobiliser that is too sensitive. If this is the case it could be necessary to reset. To do click the next web site , disconnect the battery. Then leave it off for around 15 minutes, then insert it and start the car. This will reset the key system to ensure that it is ready to accept your keys once again.
The security light is the car immobiliser's way of telling you that there is an issue with the system. If the light is on and you try to start your car, it means that the code that is stored in the ECU does not match the chip in the key. This could happen if have recently replaced your car key with a different one that has not been programmed to the vehicle, or in the event that you've had a defective swapped ECU.
If this is the situation it is recommended to take your transponder or key chip to a professional to have them properly programmed for your vehicle.

This should solve the problem when you repeat the process three times.
Programming

The immobiliser will be disengaged in the event that it doesn't recognize the code. That's why it's so difficult to beat.
Modern cars are equipped with this security system by default. This makes it extremely difficult to connect the car to a hot wire or use another key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU is aware that it's the right key and hasn't been compromised code. The system won't allow the car to start if the does not receive the correct code, and some models will even report back to the owner if a person tries to use an incorrect fob or key.
The system is not impervious to attack, but it is. Some thieves have managed to bypass the immobiliser using methods such as 'hot wiring.' This involves crossing the wrong wire in a vehicle in order to cause a malfunction in the ECU. This is a risky method and requires a lot of experience to avoid electrocuting oneself. In addition, many modern car thieves have moved to more sophisticated methods, such as using specialized apps or Bluetooth to hijack the car's data and then remotely control it using their phones.
Car owners will often get warning lights that indicate the immobiliser has gone off the rails. It can happen for many reasons however the most common reason is a defective battery in the keyfob. A simple repair should resolve this problem.
