Transponder Chip
In cars manufactured after 1995, a small electronic chip, referred to as a transponder is built into the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting when another person has an identical key. It works by transmitting an audio signal from the key to the immobiliser system. If the code stored in the computer of the car matches the signal transmitted by the key, the immobiliser will be removed and the engine will start.
The key that has the transponder chip is sometimes called a 'fob' or a "smart" key because it is more difficult to duplicate than a conventional mechanical key. Using special techniques, it is possible to duplicate a standard car key but not transponder keys. Contrary to the central locking element remote of a standard key which uses battery power, a transponder chip powered by an infrared (IR) signal transmitted by the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder needs to be turned to the ON position. The ring emits a blast of IR energy that is absorbed by the microchip inside the key. The chip responds by sending a unique code to the immobiliser in your car. The computer in the car examines the code in its memory with the transponder's and If the two codes are identical it will begin the engine.
The immobiliser will disable the engine when it detects an unauthorised key or transponder. It also stops all vital components of the car from working. Without a functioning engine, the vehicle will not be able to move, and it will be easy for criminals to hot-wire the vehicle and then drive away.

If the system is unable to identify a digital serial number from the chip in your key it will disengage the engine immobiliser, preventing the car from getting started.
The car immobiliser is a fantastic method to deter thieves, however it can occasionally be out of in sync. This could be due to interference or the system being too sensitive. If this is the situation, it may need to be reset. To do this simply disconnect the battery. repair car keys near me Leave it disconnected for about 15 minutes then reinsert it and begin the vehicle.

The security light is the vehicle immobiliser's way of telling you that there's a problem with the system. If the light is illuminated and you attempt to start your car, it means that the code that is stored in the ECU is not compatible with the chip inside the key. This can happen when your car's key was replaced with a new key that's not programmed to work with the vehicle, or when an ECU was swapped in a wrong manner.

Programming

Modern cars come with this security system in the standard configuration. This makes it extremely difficult to hot-wire a car or use a different key for starter. The system works by analyzing the chip in the key fob or a key and sending a passcode to the ECU (electronic control unit). The ECU is then able to determine that it's the right key and that the passcode hasn't been compromised. The system will not allow the car to start if the doesn't receive the correct code. Some models will even inform the owner if someone tries to use an incorrect key or fob.
The system isn't 100% secure, however. Some thieves have managed to bypass the immobiliser using methods such as 'hot-wiring.' This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking the proper key or fob is being used. This method is risky and requires a lot of knowledge to avoid electrocuting oneself. Additionally, many modern car thieves have switched to more sophisticated methods, such as using specialized apps or Bluetooth to steal a car's data and remotely control it via their phone.
