Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Most vehicles are equipped with an immobilizer to prevent theft. If your vehicle won't start after inserting the key fob there could be a problem with a transponder chip that is not sending a security code to the immobiliser system.
This is a simple fix that any auto locksmith on the Gold Coast can do. Let's look at the various components of your vehicle's immobiliser and find out what you can do.
Battery
If you are working in the field of auto repair it is crucial to focus on your shop's earnings and cost-saving opportunities. You can do this by offering key fob replacements and reprogramming for your customers. This will not only help your customers but also add to the profits of your business without having to sublet to the dealership.
The key fob battery is used to power the remote locking and opening systems. However, it doesn't provide power to the immobiliser. The immobiliser is powered by the transponder that is located in the fob, key or instrument cluster. The chip transmits a passcode to the immobilizer unit of the car, which may be built into the PCM, BCM or instrument cluster smart junction box or standalone module. The system then verifies the code to make sure it is correct. If the code isn't correct the system will disable components that are crucial to start the car, like the starter motor or ignition. The car will be impossible to start if you do not have the right key.
The immobiliser system has been highly effective in reducing car theft since its first introduction. However thieves are always trying to get around these security measures. One of these strategies is the Kia Challenge trend on TikTok, which shows how easy it can be to hot-wire an automobile.
Insurance companies are now taking the use of an immobiliser to calculate premiums. This makes it more attractive to purchase a car that has this feature. However, even vehicles equipped by the manufacturer with an immobiliser may experience problems with it. These issues are usually simple and cheap to fix. The majority times the issue is the result of a dead or dying key fob battery. A quick diagnostic test could identify the issue. If the issue continues, it could be due to electrical problems or wiring issues. It is recommended to have a professional determine the issue and fix it.
Transponder Chip
A small electronic chip, also known as transponder, is embedded into the head portion of your car keys. The technology was introduced in cars manufactured after 1995. It is also referred to as a "chip key" or a "transmitter-responder" key. Its function is to prevent your engine from starting when another person has an identical key. It works by transmitting the radio frequency signal from the key to the immobiliser system of your car. If the code on the car's computer matches the signal from the key, it will disarm the immobiliser and allow the engine to start.
The key with the transponder chip is sometimes called a 'fob' or a 'smart' key because it is more difficult to clone than a conventional mechanical key. Using specific techniques, it is feasible to copy a standard car key but not the transponder key. Transponder chips are powered by an infrared signal not battery power.
To activate the transponder the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy which is received by a microchip inside the key. The chip then responds with an individual code to the immobiliser inside your car. The car's computer checks the code stored in its memory with that from the transponder chip and if they match the engine will begin to rev.
If the immobiliser is able to detect an unauthorized transponder or key is being used it will shut down the engine and stop any of its vital components from working. The car won't move if the engine is not functioning. It's easy for a criminal hot-wire it to drive away. This is a powerful deterrent against criminals and is one of the reasons why it is essential to get your car's key immobiliser fixed when you spot a fault with it. If you don't, the security light on your car will keep flashing and it will be difficult for you to start your engine.
Security Light
The immobiliser is powered by a tiny battery that sends an electric signal to the transponder chip in your key. This is an anti theft device that blocks anyone from driving your car without the correct key. If the system is not able to recognize an electronic serial number from the chip in your key, it will shut off the engine immobiliser, which will stop the car from starting.
This car immobiliser system is effective in stopping thieves, however it can become out of in sync with the key or the transponder chip. This could be due to interference or the system being too sensitive. If this is the situation, it may need to be reset. To do this, simply disconnect the battery. After 15 minutes, you can reinstall the battery and restart the car. This will reset the key system to ensure that it is ready to accept your keys again.
The security light is an immobiliser's method of warning you of a problem. If the light is on and you try to start your vehicle, it indicates that the code stored in the ECU does not match the chip in the key. This could happen if have recently replaced your car key with another that isn't programmed to the vehicle or if you've had a bad swapped ECU.
If this is the situation, then you need to go to a professional and have the key or the transponder chip properly programmed to your vehicle. There is also the possibility that the system isn't accepting the key due to a software bug or update. To test this put your key in the ignition and turn it to the ON position but don't try to start the engine. Keep the key in this position for 10 minutes. This should cause the security light to light up and then to turn off. If it doesn't you'll need to repeat this process and wait for another 10 minutes. Repeat the process three times and the issue should be solved.
Programming
The car immobiliser stops the engine from running when the fob or key is not programmed correctly. It uses a special RFID micro-chip that can't be duplicated and comes with its own digital serial number. The immobiliser will disconnect when it doesn't recognize the code. That's why it's difficult to defeat.
Modern cars have this system as standard. This makes it very difficult to hot-wire the car or use another key for starter. The system works by checking the chip inside a key fob or key, and transmitting a passcode to the ECU (electronic control unit). The ECU is aware that it's the right key and that it doesn't have to been a compromise in the code. The system won't allow the car to start if it does not receive the correct code. Some models even inform the owner if they try to use an unapproved fob or key.
However the system isn't foolproof. Some thieves have managed to bypass the immobiliser with techniques such as 'hot wiring.' This involves crossing the wrong wires within a vehicle's wiring to fool the ECU to believe that the proper key or fob is being used. This is a risky technique and requires extensive experience to avoid electrocuting oneself. Modern car thieves are also using more advanced methods, like Bluetooth or other apps that obtain information about a vehicle and remotely manage it remotely.
Car owners will often get warning lights that indicate that the immobiliser has gone haywire. This can happen for various reasons, but the most frequent causes is a dead or defective battery in the key fob. The issue can be solved by an easy replacement.
If this doesn't work, the transponder chip might be defective or mismatched with the ECU. This is more difficult to diagnose and fix as it may require a professional locksmith or dealership. A car's immobiliser can be damaged if water is able to enter the system or if it is physically pulled away from its fob or key. If key repairs of these problems occur, it's a good idea to visit a local garage or car dealer for assistance.
