Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Most vehicles are equipped with an immobilizer that prevents car theft. If your vehicle doesn't start after inserting the key fob there could be an issue with a transponder chip that is not sending a security code to the immobiliser system.
This is a straightforward fix for any auto locksmith in Gold Coast. Let's take a look at the different components of your car immobiliser and what you can do to get it fixed.
Battery
It is important that you focus on the profit and cost-saving potentials of your auto repair shop. You can accomplish this by offering key fob replacements as well as reprogramming your customers. This will not only benefit your customers but also increase your shop's profits without the need to sublet to the dealership.
Typically the battery for the key fob powers the remote opening and locking systems. The immobiliser is not powered by the battery in the key fob. Instead, the immobiliser is dependent on the transponder chip on the fob or key. The chip transmits a passcode to the immobilizer unit of the car which can be integrated into the PCM, BCM or instrument cluster smart junction box, or standalone module. The system then checks the code to ensure that it is correct. If the code is not correct it will disable the components that are essential to starting the car, like the ignition or starter motor. The car will be nearly impossible to start if you do not have the right key.
The immobiliser has proven highly effective in reducing car theft since it was first introduced. However it is not uncommon for thieves to look for new ways to get around these security measures. One of these strategies is a recent trend called the Kia Challenge on TikTok that showcased how easy it is to connect a vehicle with hot wires.
Insurance companies are now incorporating in the use an immobiliser in calculating premiums. This makes it more appealing to purchase a vehicle with this feature. Even cars that are factory-fitted with an immobiliser might have issues. Fortunately, these issues are usually straightforward and affordable to repair. A dead or dying keyfob battery can be the reason for a malfunctioning ignition immobiliser. This can be determined by an instant diagnostic test. If the problem persists then it could be due to electrical issues or wiring issues. If this is the case, it's recommended to have a professional diagnose and repair the issue.
Transponder Chip
In cars made after 1995, a small electronic chip, referred to as transponder is integrated into the head of your car key. 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 a copy of your car key. It works by sending radio signals from the key to the immobiliser system. If the code stored in the car's computer matches the signal transmitted by the key, it will deactivate the immobiliser and allow the engine to begin.
The key that has the transponder chip is often referred to as"fob" or a "smart" key because it is more difficult to duplicate than a conventional mechanical key. It is possible to duplicate a standard key but not a transponder key. In contrast to the central locking element remote of a standard key which uses battery power, a transponder chip powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder has to be turned to the ON position. The ring emits a blast of IR energy that is picked up by the microchip inside the key. The chip then responds with a unique code to the immobiliser inside your car. The car's computer compared the code stored in its memory to the one from the transponder chip and If they are compatible, the engine will start.
If the immobiliser is able to detect an unauthorized transponder or key is in use, 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 could be easy for a criminal to connect the vehicle to a hot wire and then drive away. This is a great deterrent to criminals, which is why you should have your car key-immobiliser repaired as soon as you can in the event of a malfunction. If you don't take this action, the security light on your vehicle will continue blinking, and you won't be able to start it.
Security Light
The immobiliser is powered by a small remote car key repair battery that transmits an electrical signal to the transponder chip within your key. This is an anti-theft device that stops anyone from driving your vehicle without the right key. If the system cannot detect an electronic serial number from the chip in your key, it will disable the engine immobiliser to stop the car starting.
This system for car immobilisation is an an effective way to stop thieves, but it is also possible for it to become out of sync with the key or transponder chip. This can be due to interference or a system that is too sensitive. This may need the system to be 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 allow it to accept the key again.
The security light is an immobiliser's way of alerting you to an issue. If the light is on and you try to start your car, it means that the code stored in the ECU does not match the chip in the key. This could happen if you have recently replaced your car's key with a different one that has not been programmed to the vehicle or in the event that you've had a defective swapped ECU.
If this is the case, then it's time to go to a professional for assistance and get the the transponder chip properly programmed to your vehicle. It's possible that your system isn't able to accept the key because of a software update or bug. To test, insert your key in the ignition and then turn it to the ON position. Don't try to start the car. Keep the key in this position for ten minutes. The security light should come on, then go off. If it does not then you must repeat the process and wait for another 10 minutes. This should solve the problem when you repeat the process three times.
Programming
A car immobiliser stops a car's engine from running without a correctly programmed key or fob. It is a unique RFID chip that is unable to be copied and has a digital serial number. The immobiliser will stop working in the event that it doesn't recognize the code. It's hard to beat.
Modern cars have this system as standard. This makes it very difficult to hot-wire a vehicle or use a different key for starter. The system works by checking the chip inside the key fob or key, and sending a passcode back to the ECU (electronic control unit). 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 doesn't receive the correct code. Some models will even notify the owner if a person tries to use a wrong key or fob.
The system isn't completely foolproof, however. Some thieves have bypassed the immobiliser with techniques such as 'hot wiring.' This involves crossing the wrong wires in a vehicle's wiring to fool the ECU to believe that the appropriate fob or key is being used. However, this is pretty dangerous and requires a lot of experience to accomplish it without cutting yourself. Additionally, many modern car thieves have moved to more sophisticated methods like using specialized apps or Bluetooth to hijack the car's data and then remotely control it from their mobile.
Car owners often see warning lights that indicate an immobiliser gone haywire. This could be due to various reasons but the most frequent reason is a defective battery in the keyfob. A simple replacement can fix this issue.
If this does not work, it could be that the transponder chip is defective or the ECU is not matched. This is harder to diagnose and fix as it may require a specialist locksmith or dealership. However, a car immobiliser can also be damaged due to water ingress or even physically being removed from the fob or key. If any of these issues occur, it's recommended to visit the nearest garage or dealer for assistance.
