The key fob battery powers the remote locking and opening systems. The immobiliser is not powered by the key fob battery. The immobiliser is powered by the transponder that is located in the key, fob or instrument cluster. The chip transmits a code from the key or fob to the immobilizer module of the car, which could 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 will check the code to ensure that it is correct. If the code is not correct the system will disable elements that are crucial to starting the car, like the starter motor or ignition. The car will be impossible to start if you don't have the right key.

Even vehicles that are factory-fitted with an immobiliser may have problems. Fortunately, these problems are usually easy and cheap to repair. A dead or dying keyfob battery can be the cause of a malfunctioning ignition immobiliser. A quick diagnostic test could identify the issue. If the issue persists, it could be due to electrical issues or wiring issues. If this is the case, it's recommended to consult a professional for a diagnosis and repair the issue.
Transponder Chip
A tiny electronic chip, called a transponder, is built in the head of your car keys. This technology was introduced in cars made after 1995. Also known as a 'chip key or a 'transmitter and responder key, it's designed to prevent the engine from starting if someone else has a 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 matches the signal sent from the key, it will disable the immobiliser and allow the engine to begin.
The key with a transponder can also be referred to as a "fob" or a "smart" key, because it is more difficult to duplicate than a mechanical key. Using special methods, it is possible to duplicate a standard car key, but not transponder keys. Transponder chips are powered by an infrared signal and not battery power.
To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits IR energy that is detected by a microchip within the key. The chip then responds with a unique code to the immobiliser in your car. The car's computer compares the code in its memory with that from the transponder chip, and If they are compatible, the engine will start.
The immobiliser will shut down the engine in the event of an unauthorized key or transponder. It also blocks any essential components of the vehicle from functioning. Without a functioning engine, the car will not be able to move and it would be very easy for criminals to wire the vehicle and then drive away. This is a powerful deterrent to crime and it is one of the reasons why it is essential to get your car's key immobiliser repaired immediately you discover any issue with it. If you do not take action then the security light on your vehicle will continue flashing and you will not be able to start it.
Security Light
The immobiliser uses a small battery to send an electrical signal to the chip inside your key. This anti-theft device prevents anyone from starting their car without the proper keys. If the system cannot detect a digital serial number from the chip on your key, it will disable the engine immobiliser to prevent the car from starting.
The car immobiliser is a great method to deter thieves, but it can sometimes be out of in sync. This can be caused by interference or the system being too sensitive. This may require a reset. To do this, simply disconnect the battery. After 15 minutes, you can reinstall the battery and restart the vehicle. This will reset the system and make it ready to accept your key again.
The security light is an immobiliser's method of warning you of a problem. If you attempt to start the car but the light is solid on it means that the chip in your key isn't in sync with the code that is stored in the ECU. This can occur in the event that your car's key was replaced with a new one that is not compatible with the vehicle, or if an ECU was swapped in a wrong manner.
If this is the case then it's time to go to a professional to have the the transponder chip properly programmed to your vehicle. It is possible that the system will not accept the key due to a software upgrade or glitch. To test, put your key in the ignition and then turn it to the ON position. Do not try to start the car. The key should remain in this position for 10 minutes. This will cause the security light to come on and then to go off. If it doesn't work, you'll need to repeat the procedure and wait another 10 minutes. Do this three times and the problem should be solved.
Programming
The car immobiliser stops the engine from running if the fob or key is not properly programmed. It makes use of a unique RFID microchip that cannot be duplicated and has its own digital serial number. The immobiliser will stop working in the event that it is unable to recognize the code. That's why it's so difficult to defeat.
Modern cars are fitted with this security system as standard. This makes it very difficult to wire the car hot or use a different key as a starter. The system works by analyzing the chip in the key fob or key, and transmitting a passcode to the ECU (electronic control unit). The ECU is then able to determine that it's the correct key and that the passcode isn't compromised. The system will not allow the car to start if it doesn't receive the correct code. Some models will even inform the owner if a person tries to use a wrong fob or key.
The system is not 100% secure, however. Some thieves have been able to bypass the immobiliser using methods like hot-wiring. This involves crossing the wrong wire in a vehicle to fool the ECU. This is a risky technique and requires a lot of expertise to avoid electrocuting yourself. Plus, a lot of modern car thieves have switched to more sophisticated methods such as using specialised apps or Bluetooth to hijack the car's data and then remotely control it using their phones.
Car owners often see warning lights that indicate an immobiliser that has gone out of control. It can occur for a variety of reasons, but the most common is a faulty or dead battery in the key fob. The issue can be solved by replacing the battery.
If this does not work, it could be that the transponder chip may be defective or the ECU is not matched. This is more complicated to diagnose and fix because it requires a specialist car locksmith or dealership. A car's immobiliser can be damaged if water manages to get into the system or is physically pulled away from its fob or key. If any of these problems occur it's recommended to visit an auto garage or a local dealer to seek assistance.
