The key fob battery powers the remote locking and opening systems. However, it does not supply power to the immobiliser. The immobiliser is powered by a transponder located in the fob, key or instrument cluster. The chip transmits a passcode from the fob or key to the immobilizer unit of the car, which can be integrated into the PCM (power control module) BCM (brake control module for brake control) instrument clusters, smart junction boxes, or standalone modules. The system examines the code to ensure that it is correct. If it's not, the system will disable components crucial to starting the vehicle, like the starter motor or ignition. The car will be impossible to start if the driver doesn't have the right key.
Since its inception the immobiliser has proved to be an extremely effective tool for decreasing car theft. Despite this the fact that thieves are always looking for new ways to bypass these security measures.

Even cars equipped with an immobiliser could have issues. These problems are often easy and cheap to fix. The majority times, a faulty immobiliser is caused by the dying or dead key fob battery. This can be confirmed with a quick diagnostic test. If the issue continues, it could be due to electrical issues or wiring issues. If this is the case, it's best to have a professional diagnose and fix the issue.
Transponder Chip
A small electronic chip, also known as transponder, is embedded into the head portion of your car keys. This technology was introduced in cars manufactured after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its function is to prevent the engine from starting when you have an identical key. It works by sending an audio signal from the key to your immobiliser. If the code 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 a transponder can also be referred to as a "fob" or a "smart" key due to the fact that it is more difficult to copy than mechanical keys. It is possible to duplicate a standard key, but not a transponder key. Contrary to the remote central locking element of a conventional key which uses battery power, a transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits a flash of IR energy that is detected by the microchip within the key. The chip then sends an individual code to the immobiliser in your car. The car's computer compared the code stored in its memory with the one from the transponder chip and if they match the engine will be able to start.
If the immobiliser detects that an unauthorized transponder or key is being used, it will disable the engine and prevent any of its vital components from working. The car won't move when the engine isn't functioning. It's easy for a criminal to hot-wire it and then drive off. This is a powerful deterrent against crime and it is one of the reasons why it's important to have your car's key immobiliser fixed as soon as you notice any issue with it. If you don't take this action then the security light on your vehicle will continue blinking, and you won't be able to begin it.
Security Light
The immobiliser makes use of a tiny battery to send an electrical signal to the chip in your key. This is an anti-theft device that stops anyone from driving your vehicle without the right key. If the system is unable to detect a digital serial number from the chip on your key, it will disable the engine immobiliser to prevent the car starting.
The car immobiliser system is an an effective way to stop thieves but sometimes it can get out of in sync with the key or the transponder chip. This could be due to interference or the system being too sensitive. This may require a reset. To do this, disconnect the battery. Then leave it off for around 15 minutes before reinstalling it and begin the car. This will reset the key system, so that it is ready to accept keys once more.
The security light is an immobiliser's way of alerting you to an issue. If the light is on and you try to start your car, it means that the code in the ECU is not compatible with the chip on the key. This can occur when your car's key has been replaced by an alternative key that is not programmed for the vehicle, or if an ECU has been swapped incorrectly.
If this is the case you should bring your transponder key or chip to a professional to have them properly programmed for your car. It's possible that the system will not accept the key due to a software update or glitch. To test this, insert your key in the ignition and turn it to the ON position. Do not try to start the vehicle. The key should remain in this position for ten minutes. This should cause the security lights to light up and then to turn off. If it doesn't then you'll have to repeat the procedure and wait another 10 minutes. Do this three times and the issue will be resolved.
Programming
A car immobiliser prevents a car's engine from running without a key that is programmed correctly or fob. It is a unique RFID chip that cannot be copied and is equipped with a digital serial number. The immobiliser will stop working if it does not recognise the code. It's hard to beat.
Modern cars have this system as standard. This makes it very difficult to hot-wire a vehicle or utilize a different 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 that there hasn't been compromised code. The system will not allow the car to begin in the event that it does not receive the correct code. Some models even notify the owner when they attempt to use an unapproved fob or key.
The system is not foolproof, however. Some thieves have managed to bypass the immobiliser by using methods like 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. However, this is pretty dangerous and requires a lot of experience in order to accomplish it without damaging yourself. Plus, a lot of modern car thieves have shifted to more sophisticated methods, such as using specialized apps or Bluetooth to hijack a car's data and remotely control it via their phones.
Car owners often be greeted by warning lights that indicate an immobiliser gone haywire. This could be due to various reasons however the most common reason is a defective battery in the keyfob. A simple repair should resolve the issue.
If this doesn't work, it could be that the transponder chip is defective or the ECU is not compatible. This is more difficult to fix and diagnose as it may require a specialist locksmith or dealership. A car immobiliser may also be damaged if water manages to get into the system, or if it is physically removed from its car key circuit board repair fob or key.
