Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Currently, most vehicles come equipped with an engine immobilizer in order to prevent car theft. If your vehicle won't start after inserting the key fob, there may be a problem with a transponder chip that is not transmitting an encryption code to the immobiliser system.
This is a quick fix that any auto locksmith on the Gold Coast can do. Let's examine the different components of your vehicle immobiliser to see what you can do.
Battery
If you are in the auto repair business it is crucial to be aware of your shop's earnings and cost-saving opportunities. You can accomplish this by providing key fob replacements and reprogramming to your customers.

The key fob battery powers the remote locking and opening systems. However, it doesn't power the immobiliser. The immobiliser is powered by the transponder that is located in the key, fob or instrument cluster. The chip transmits a passcode to the car's immobilizer unit, which may be built into the PCM, BCM, instrument cluster smart junction box, or standalone module. The system will check the code to ensure that it is correct. If it is not then the system will disable elements that are crucial to the start of the vehicle, like the starter motor or ignition. This will make the vehicle nearly impossible to start without the correct key.
The immobiliser system has proven extremely effective at decreasing car theft since its introduction. However the thieves are always seeking ways to bypass these security measures. One of these techniques is an upcoming trend called the Kia Challenge on TikTok that showcased how easy it is to connect a vehicle with hot wires.
Many insurance companies are now incorporating in the use of an immobiliser when calculating premiums, which makes it more attractive to buy a car that already has this feature.

A dead or dying keyfob battery can be the reason for a malfunctioning ignition immobiliser. This can be confirmed with a quick diagnostic test. If the issue persists it could be due to other causes for the vehicle's misbehaviour, including electrical issues or a wiring problem. If this is the case, it's recommended to have a professional diagnose and fix the issue.
Transponder Chip
In cars manufactured after 1995, a small electronic chip referred to a transponder is built into the head of your car key. It is also known as a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting if you have a duplicate of your key. It works by transmitting a radio frequency from the key to the immobiliser system. If the code in the car's computer matches that signal from the key, it will deactivate the immobiliser and allow the engine to begin.
The key with the transponder is also called a "fob" or a "smart" key, as it is more difficult to copy than mechanical keys. It is possible to duplicate a traditional key, but not a transponder key. Contrary to the remote central locking element of a standard key which uses battery power, a transponder chip is powered by an infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a blast of IR energy which is absorbed by the microchip inside the key. The chip then responds with an individual code to the immobiliser of your car. The computer in the car examines the code in its memory to the transponder's and when the two codes match it will begin the engine.
The immobiliser will shut down the engine if it detects an unauthorised key or transponder. It will also prevent all vital components of the car from working. Without a functioning engine, the vehicle will read more not be able to move, and it will be easy for criminals to hot-wire the vehicle and drive away.

If you don't fix it, the security light in your car will keep flashing and it will be impossible to start your engine.
Security Light
The immobiliser is powered by a tiny battery that sends an electric signal to the transponder chip inside your key. This device is designed to prevent anyone from starting the car without the correct keys. If the system is unable to detect a digital serial from the chip in your key, it will shut off the engine immobiliser to stop the car starting.
The car immobiliser is a great method of deterring thieves, but it can sometimes be out of in sync. This could be due interference or an immobiliser that is too sensitive. If this is the case, it may need to be reset. To do this, just disconnect the battery. After 15 minutes, reinstall the battery and restart the vehicle. This will reset the system and allow it to accept the key again.
The security light is an immobiliser's method of warning you of a problem. If you attempt to start the car and the light stays on it means that the chip in your key doesn't match the code that is stored in the ECU. This can occur if your car key has been replaced by an alternative key that is not compatible with the vehicle, or if the ECU was swapped in a wrong manner.
If this is the situation, then it's time to talk to a professional to have the transponder or key chip properly programmed to your vehicle. It's possible that your system won't accept the key because of a software update or bug. To test this, put your key in the ignition and turn it to ON but don't try to start the engine. Let the key remain in this position for ten minutes. The security light should turn on, then go off. If it doesn't, you'll have to repeat the procedure and wait another 10 minutes.

The immobiliser will be disengaged when it is unable to recognize the code. It's difficult to beat.
Modern cars have this system as standard. This makes it very difficult to hot-wire the car or use a different key as a starter. The system works by checking the chip inside the key fob or key, and sending 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 hasn't been compromised. The system won't permit the car to start if it does not receive the correct code, and some models will even inform the owner if a person tries to use a wrong key or fob.
However the system isn't foolproof. Some thieves have managed get more info to bypass the immobiliser using methods like hot-wiring. This involves using the wrong wiring in an automobile to cause a malfunction in the ECU. But, this technique is quite dangerous and requires a lot of knowledge of how to carry out the procedure without damaging yourself. Additionally, many modern car thieves have shifted to more sophisticated methods such as using specialised 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 that has gone out of control. This here could be due to various reasons but the most frequent one is a malfunctioning battery in the keyfob. A simple replacement can fix this problem.
If this doesn't work it could be because the transponder chip may be defective or the ECU is not compatible.
