This will not only benefit your customers but also boost the profits of your shop without subletting to the dealership.
Typically the battery for the key fob powers the remote opening and locking systems. However, it doesn't provide power to the immobiliser. Instead, the immobiliser depends on the transponder chip that is located on the fob or key. The chip transmits a passcode from the key or fob to the immobilizer unit in 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 will check the code to ensure it's correct. If it's not then the system will disable components crucial to starting the vehicle, such as the ignition or starter motor. This will make the car almost impossible to start if you don't have the right key.
The immobiliser has proven highly effective in decreasing car theft since its introduction. However it is not uncommon for thieves to look for new ways to bypass these security measures. One of these strategies is a recent trend known as the Kia Challenge on TikTok that showcased how easy it is to wire a vehicle.
Insurance companies are now taking in the use an immobiliser in calculating premiums. This makes it more appealing to buy a car with this feature. Even cars that are factory fitted with an immobiliser might have problems. These issues are usually simple and affordable to fix.

If the problem persists it could be due to other causes for the vehicle's irregular behavior, such as electrical issues or a wiring issue. If this is the case, it's recommended to seek out a professional to diagnose and fix the problem.
Transponder Chip
A small electronic chip, called transponder, is incorporated into the head portion of your car keys. This technology was first introduced in vehicles manufactured after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to prevent the engine from starting when someone else has an identical key. It works by sending the radio frequency signal from the key to the immobiliser system in your car. If the code stored in the computer of the car is in line with the signal sent by the key, the immobiliser will be removed and the engine will begin to run.
The key that is equipped with a transponder chip is sometimes called"fob" or a smart key because it is much more difficult to clone than a conventional mechanical key. Using specific techniques, it is possible to copy a standard car key however, not transponder keys. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder chip, the ignition cylinder must be turned to the ON position. The ring emits a burst of IR energy, which is picked up by the microchip inside the key. The chip responds by transmitting a unique code to the immobiliser in your car. The computer in the car analyzes the code stored in its memory to the one on the transponder and if the two codes match it will start the engine.
If the immobiliser detects that an unauthorized transponder or key is being used, it will disable the engine and prevent the essential components from functioning. Without a functioning engine, the vehicle won't be able to move and it would be very easy for a criminal to wire the vehicle and drive away. This is a powerful way to deter crime and it is one of the main reasons why it's essential to have your car key immobiliser repaired as soon as you notice any issue with it. If you don't do this, the security light in your vehicle will continue to flash and it will be impossible for you to start your engine.
Security Light
The immobiliser is powered by a small battery that sends an electric signal to the transponder chip inside your key. It is an anti-theft device that stops anyone from starting your vehicle without the right key. If the system is unable to detect a digital serial number from the chip inside your key it will disengage the engine immobiliser and prevent the car from beginning.
The car immobiliser is a fantastic method to deter thieves, but it could occasionally be out of in sync. This can be due to interference or the system being too sensitive. If this is the case, it may need to be reset. To do this, disconnect the battery. After 15 minutes, you can reinstall the battery and then restart the car. This will reset the key system, so that it is ready to accept your keys once again.
The security light is an immobiliser's way of alerting you to the presence of a problem. If the light is on and you attempt to start your car, it is a sign that the code stored in the ECU is not compatible with the chip inside the key. This could happen in the event that your car's key was replaced with an alternative key that is not programmed for the vehicle, or when an ECU was swapped in a wrong manner.
If this is the case you should bring your transponder key or chip to a professional for them properly programmed for your car. It's possible that your system isn't able to accept the key due to a software update or bug. To test this, put your key in the ignition and switch it to the ON position but don't try to start the engine. The key should remain in this position for ten minutes. The security light should come on, then turn off. If it doesn't work, you'll have to repeat the procedure and wait another 10 minutes. Repeat the process three times, and the issue will be resolved.
Programming
An immobiliser for cars prevents a car's engine from running without a correctly programmed key or fob. It utilizes a specific 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 are fitted with this security system in the standard configuration. This makes it difficult to hot-wire a car or use a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU recognizes that it is the correct key and hasn't been compromised code. The system won't allow the car to start if it does not receive the correct code. Some models even notify the owner if they try to use a wrong fob or key.
The system isn't completely impervious to attack, but it is. Some thieves have been able to bypass the immobiliser by using techniques like 'hot-wiring'. This involves crossing the wrong wires through a vehicle's wiring to fool the ECU into thinking that the correct key or fob is being used. This is a risky method and requires extensive expertise to avoid electrocuting yourself. Plus, a lot of modern car thieves have moved over to more advanced methods, such as using specialized apps or Bluetooth to hijack a car's data and remotely control it via their phones.
Owners of cars will often notice warning lights that signal an immobiliser malfunctioning. This could be due to a variety of reasons, but the most common one is a faulty battery in the keyfob. This problem can be fixed by a simple replacement.
If this doesn't work the transponder chip could be defective or not compatible with the ECU. This is more difficult to diagnose and fix as it could 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 fob or key. If you encounter any of these problems, it is a good idea that you visit the local car dealer or garage for assistance.
