Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Today, the majority of vehicles are equipped with an engine immobilizer in order to protect against theft of cars. If your vehicle doesn't start after inserting the key fob it could be a problem with a transponder which isn't sending a security signal to the immobilizer.
This is a straightforward fix that any auto locksmith on the Gold Coast can do. Let's take a look at the different parts of your vehicle's immobiliser and see what you can do.
Battery
It is crucial to focus on the cost-savings and revenue 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 assist your customers but will also add to the profits of your business without having to sublet to the dealership.
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 fob, key or instrument cluster. This chip transmits a code to the car's immobilizer device that can be integrated into the PCM, BCM, the instrument cluster smart junction box or standalone module. The system checks the code to ensure it's correct. If it is not, the system will disable parts that are essential to start the vehicle, such as the ignition or starter motor. The car will be nearly impossible to start if you don't have the correct key.
The immobiliser system has been extremely effective at reducing car theft since its first introduction. However thieves are always trying to get around these security measures. One of these is the Kia Challenge trend on TikTok that demonstrates how easy it can be to hot-wire an vehicle.
Insurance companies are now factoring in the use an immobiliser in calculating premiums. This makes it more attractive to purchase a vehicle with this feature. Even cars that are factory-fitted with an immobiliser might be prone to problems. Fortunately, these issues are usually easy and cheap to fix. A dying or dead keyfob battery is usually the cause of a malfunctioning ignition immobiliser. A quick diagnostic test will identify the issue. If the problem persists and continues to recur, there could be other reasons for the car's irregular behavior, such as electrical issues or a wiring issue. If this is the case, it's best to have a professional diagnose and repair the problem.
Transponder Chip
In vehicles manufactured after 1995, a tiny electronic chip, referred to as a transponder is built into the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting when you have a duplicate of your key. It works by sending a radio frequency signal from the key to the immobiliser system inside your car. If the code in the car's computer matches the signal from the key, it will deactivate the immobiliser and allow the engine to begin.
The key that is equipped with a transponder chip is often referred to as"fob" or a smart key because it is much more difficult to duplicate than a conventional mechanical key. Using specific methods, it is possible to duplicate a standard car key however, not the transponder key. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder chip, the ignition cylinder needs to be switched to ON. The ring emits a burst of IR energy, which is picked up by the microchip within the key. The chip responds by sending a unique code to your car's immobiliser. The computer in the car analyzes the code stored in its memory with the one on the transponder and if the two codes match it will begin the engine.
If the immobiliser is able to detect an unauthorised transponder or key is being used it will shut down the engine and prevent any of its vital components from working. The car won't move in the event that the engine is not functioning. It's easy for a criminal to hot-wire it and drive off. This is a powerful deterrent to criminals and is one of the main reasons why it is essential to get your car's key immobiliser repaired when you spot a fault with it. If you don't, the security light on your car will continue to flash and it will be difficult for you to start your engine.
Security Light
The immobiliser makes use of a tiny battery to send an electrical signal to the chip inside your key. This anti-theft device prevents anyone from starting the car without the correct keys. If the system is unable to detect a digital serial number from the chip inside your key, it will deactivate the engine immobiliser, preventing the car from getting started.
This car immobiliser system is effective in stopping thieves, however it can become out of in sync with the key or transponder chip. This could be due to interference or the system being too sensitive. This may require an adjustment. To do this, just disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and begin the car. This will reset the key system to ensure that it is ready to accept keys once more.
The security light is the vehicle immobiliser's way of telling you that there's a problem with the system. If the light is illuminated and you attempt to start your car, it means that the code in the ECU is not compatible with the chip inside the key. This could happen if have recently replaced your car key with another that was not programmed to your vehicle or when you've had a damaged swapped ECU.
If this is the case you should take your key or transponder chip to a professional to get them properly programmed for your vehicle. There is also the possibility that the system is not accepting the key due to a software bug or update. To test this, place your key in the ignition and turn it to the ON position but don't attempt to start the engine. The key should remain in this position for ten minutes. This should cause the security lights to come on and then to go off. If it doesn't then you'll have to repeat the process and wait another 10 minutes. This should solve the problem when you repeat the process three times.
Programming
An immobiliser for cars prevents a car's engine from running without a properly programmed key or fob. It uses a special RFID microchip that cannot be duplicated and has its own serial number. The immobiliser will be disengaged if it doesn't recognise the code. That's why it's difficult to defeat.
Modern cars come with this security 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 analyzing the chip inside a key fob or a key and transmitting a passcode to the ECU (electronic control unit). The ECU is then able to determine that it's the right key and that the code hasn't been compromised. The system will not allow the car to begin when it doesn't receive the correct code. Some models even inform the owner if they attempt to use an incorrect fob or key.
The system is not 100% secure, however. Some thieves have gotten around the immobiliser with techniques such as 'hot-wiring.' This involves crossing the wrong wire in a vehicle to cause a malfunction in the ECU. However, this method is pretty dangerous and requires a lot of repair broken car key experience in order to do it without damaging yourself. Plus, a lot of modern car thieves have shifted over to more advanced methods like using specialized apps or Bluetooth to hijack the car's data and then remotely control it using their phones.
Car owners often see warning lights that indicate an immobiliser malfunctioning. This could be due to a variety of reasons however the most common reason is a defective battery in the keyfob. A simple replacement should fix this issue.
If this isn't working the transponder chip could be defective or not compatible with the ECU. This is more complicated to fix and diagnose because it requires a specialist car locksmith or dealership. A car's immobiliser can be damaged if water manages to get into the system, or if it is physically pulled away from its fob or key. If any of these problems occur, it's recommended to visit a local garage or car dealer to seek assistance.
