The chip transmits a passcode to the immobilizer unit of the car that can be integrated into the PCM, BCM or instrument cluster smart junction box or standalone module. The system then verifies the code to ensure it is correct. If it's not, the system will disable components crucial to starting the vehicle, like the starter motor or ignition.

Transponder Chip
A small electronic chip, called a transponder, is built in the head of your car keys. The technology was introduced in cars made after 1995. It is also referred to as a "chip key" or a "transmitter-responder" key. Its goal is to prevent the engine from starting when another person has an identical key. It works by sending a radio frequency signal from the key to the immobiliser system inside your car. If the code stored in the car's computer matches the signal transmitted by the key, it will disable the immobiliser and allow the engine to start.
The key with the transponder is also referred to as a "fob" or a "smart" key, as it is more difficult to duplicate than mechanical keys. It is possible to duplicate a conventional key, but not a transponder one. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip the ignition cylinder has to be turned on. The ring emits a burst of IR energy, which is detected by the microchip within the key. The chip responds by transmitting a unique code to your car's immobiliser. The computer in the car analyzes the code stored in its memory with the one on the transponder and when the two codes match it will begin the engine.
The immobiliser will shut down the engine when it detects an unauthorized key or transponder. It will also prevent all vital parts of the car from working.

If the system can't detect a serial number digital from the chip inside your key, it will deactivate the engine immobiliser and prevent the car from starting.
The car immobiliser is a great method of deterring thieves, but it can sometimes be out of the sync. This could be due interference or a system that is too sensitive. If this is the situation, it might need to be reset. To do this, just disconnect the battery. After 15 minutes, reinstall the battery and then restart the car. This will reset the system and allow it to accept your key once more.
The security light is a way of warning you of a problem. If the light is on when you attempt to start your car, it is a sign that the code in the ECU does not match the chip on the key. This could happen if have recently replaced your car's key with a different one that isn't programmed to your vehicle or if you've had a bad swapped ECU.
If this is the case then you need to go to a professional and have the transponder or key chip properly programmed to your vehicle. There is also the possibility that the system is not accepting the key because of an issue with the software or an update. To test this, put your key in the ignition and switch it to ON but don't attempt to start the engine. Keep the key in this position for 10 minutes. The security light should turn on, then go off. If it doesn't work, you'll need to repeat the procedure and wait another 10 minutes. This should solve the issue if you repeat it three times.
Programming

Modern cars are fitted with this security system by default. This makes it very difficult to wire a car or use a different key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU then knows that it's the correct key and that the code hasn't been compromised. The system won't allow the car to start if the doesn't receive the correct code, and some models will even inform the owner if a person tries to use an unapproved key or fob.
The system isn't completely 100% secure, however. Some thieves have bypassed the immobiliser with techniques such as 'hot-wiring.' This involves using the wrong wiring in an automobile to fool the ECU. This is a risky method and requires extensive expertise to avoid electrocuting yourself. Plus, a lot of 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 phone.
Owners of cars will often be greeted by warning lights that indicate an immobiliser gone haywire. It can happen for a variety of reasons but the most frequent reason is a defective battery in the keyfob. This problem can be fixed by an easy replacement.
