The immobiliser is powered through the transponder located in the fob, key or instrument cluster. The chip transmits a passcode from the fob or key 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 cluster smart junction boxes or standalone modules. The system then verifies the code to ensure it is correct. If the code is incorrect the system will disable components that are essential to start the car, such as the ignition or starter motor. This will make the vehicle nearly impossible to start if you don't have the right key.
The immobiliser system has been extremely effective at decreasing car theft since it was first introduced. Even so, thieves are constantly seeking ways to bypass these security measures. One of these strategies is a recent trend called the Kia Challenge on TikTok that demonstrated how easy it is to connect a vehicle with hot wires.
Insurance companies are now factoring in the use an immobiliser in calculating premiums. This makes it more attractive to purchase a car that has this feature. Even vehicles that are factory-fitted with an immobiliser may have issues. Fortunately, these problems are usually simple and inexpensive to fix. A dying or dead keyfob battery is usually the cause of a malfunctioning ignition immobiliser. A quick diagnostic test could identify the issue. If the issue continues, 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 fix the problem.
Transponder Chip
A tiny electronic chip, also known as transponder, is embedded inside the head portion of your car keys. The technology was introduced in cars manufactured after 1995. Also known as a chip key' or a 'transmitter and responder' key, it is designed to stop the engine from starting if someone else has the same key. It works by transmitting a radio frequency signal from the key to the immobiliser system inside your car. If electronic car key repair stored in the car's computer is in line with the signal from the key, it will deactivate the immobiliser and allow the engine to start.
The key with the transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than mechanical keys. Utilizing specific methods, it is possible to duplicate a standard car key but not transponder keys. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder chip, the ignition cylinder has to be switched to ON. The ring emits a blast of IR energy which is picked up by the microchip within the key. The chip responds with an individual code to the immobiliser in your car. The computer in the car compares the code stored in its memory with the transponder's and when the two codes match, it will start the engine.
If the immobiliser is able to detect an unauthorised transponder, key or other device is being used it will shut down the engine and prevent any of its vital components from working. Without a functioning engine, the vehicle will not be able to move, and it would be very easy for a criminal to connect the vehicle to a hot wire and then drive off. This is a powerful deterrent to criminals, which is why you should have your car's key-immobiliser repaired as soon as you can in the event of a malfunction. If you don't do this, the security light in your car will continue to flash and it will be difficult to start your engine.
Security Light
The immobiliser utilizes a small battery to transmit an electrical signal to the chip in your key. This anti-theft device stops anyone from starting the car without the proper keys. If the system is unable to detect a serial number digital from the chip inside your key, it will disable the engine immobiliser and stop the car from starting.
This system for car immobilisation is an an effective way to stop thieves, but it is also possible for it to get out of in sync with the key or the transponder chip. This could be due to interference or the system is too sensitive. This could need a reset. To do this, simply disconnect the battery. Leave it disconnected for about 15 minutes, then insert it and start the vehicle. This will reset the key system so that it is ready to accept your keys again.
The security light is an immobiliser's method of warning you of the presence of a problem. If you attempt to start the car but the light is solid on it means that the chip in your key doesn't match the code stored in the ECU. This can occur when your car's key was replaced with a new one that is not compatible with the vehicle, or if the ECU was not swapped correctly.
If this is the situation you should bring your transponder key or chip to a professional to get them correctly programmed for the vehicle you are driving. It's possible that the system isn't able to accept the key because of a software update or glitch. To test this, put your key in the ignition and turn it to ON but don't attempt to start the engine. Let the key stay in this position for 10 minutes. This will cause the security light to light up and then to go off. If it does not you'll need to repeat the procedure and wait for another 10 minutes. Repeat the process three times and the problem is likely to be solved.
Programming
A car immobiliser prevents the car's engine from operating without a properly programmed key or fob. It uses a special RFID chip that cannot be duplicated and has a unique digital serial number. The immobiliser will disengage when it is unable to recognize the code. It's hard to beat.
Modern cars have this system as standard. This makes it very difficult to hot-wire a car or use a different key as a starter. The system operates by sending a passcode from the key fob to the ECU. The ECU recognizes that it is the correct key and that it doesn't have to be compromised code. The system will not allow the car to start in the event that it does not receive the correct code. Certain models will even notify the owner if they try to use an unapproved fob or key.
However, the system is not impervious to theft. Certain thieves have been able to bypass the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wires through the wiring of a vehicle, which fools the ECU into thinking that the proper key or fob is being used. However, this is extremely risky and requires a lot of experience in order to do it without electrocuting yourself. Plus, a lot of modern car thieves have switched over to more advanced methods such as using specialised apps or Bluetooth to steal the car's data and then remotely control it from their phone.
Car owners will frequently be greeted by warning lights that indicate an immobiliser gone haywire. It can occur for a variety of reasons, but the most frequent causes is due to a damaged or dead battery in the key fob. A simple repair should resolve this problem.
If this doesn't work the transponder chip could be defective or not compatible with the ECU. It is more difficult to determine and fix, as it can involve a specialist car locksmith or dealership. However, a car's immobiliser can also be damaged due to water intrusion, or even being removed from the fob or key. If any of these problems occur it's recommended to visit a local garage or car dealer for assistance.
