Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Most cars are equipped with an immobilizer system that stops 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 authorization code to the immobilizer system.
This is a simple fix that any auto locksmith on the Gold Coast can do. Let's examine the different elements of your car's immobiliser and what you can do to fix it.
Battery
It is crucial to focus on the profit and cost-saving potentials of your auto repair shop. You can achieve this by providing key fob replacements and reprogramming to your customers. This will not only benefit your customers, but also increase your shop's profits without having sublet the dealership.
Typically the key fob battery powers the remote opening and locking systems. The immobiliser isn't powered by the key fob battery. The immobiliser is powered by a transponder that is located in the key, fob or instrument cluster. The chip transmits a code from the fob or key to the immobilizer unit of the car, which could 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 checks the code to ensure it is correct. If it's not it is, the system will shut down elements that are crucial to the start of the vehicle, like the ignition or starter motor. This will make the car almost impossible to start if you don't have the right key.
Since its introduction, the immobiliser has been an extremely effective tool for reducing the theft of cars. Even so, thieves are constantly trying to get around these security measures. One of these strategies is a recent trend called the Kia Challenge on TikTok that showed how easy it was to connect a vehicle with hot wires.
Insurance companies are now incorporating the use of 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 may be prone to problems. These issues are usually simple and inexpensive to solve. Most times the issue is the result of the dying or dead key fob battery. A quick diagnostic test will reveal this issue. If the issue persists, then there might be other causes for the vehicle's behavior, such as electrical issues or a wiring problem. It is recommended to seek out a professional to identify the issue and then fix it.
Transponder Chip
A tiny electronic chip, called transponder, is incorporated into 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 created to stop the engine from starting if someone else has a copy of your car key. It functions by sending an audio frequency signal from the key to the immobiliser system inside your car. If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will be removed and the engine will be able 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 copy than a mechanical key. It is possible to duplicate a traditional key but not a transponder key. Transponder chips are powered by an infrared signal not battery power.
To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits IR energy which is received by a microchip within the key. The chip responds by transmitting a unique code to the immobiliser of your car. The here computer in the car examines the code in its memory with the transponder's and If the two codes are identical, it will start the more info engine.
If the immobiliser detects that an unauthorised transponder, key or other device is in use it will shut down the engine and block the essential components from functioning. The car will not move in the event that the engine is not working. It is easy for a criminal to hot-wire it and then drive off. This is an effective deterrent to criminals, which is the reason why you should get your car key-immobiliser repaired as soon as you can when it has a problem. If you do not take action, the security light on your car will continue flashing and you will not be able to begin it.
Security Light
The immobiliser utilizes a small battery to transmit an electrical signal to the chip inside your key. It is an anti-theft device that prevents anyone from driving your vehicle without the right key. If the system is unable to identify a digital serial number from the chip inside your key, it will disable the engine immobiliser, preventing the car from getting started.
The car immobiliser system is an effective in stopping thieves, however it can become out of connection with the key or the transponder chip. This could be due to interference or a system that is too sensitive. This may require the system to be reset. To do this, simply disconnect the battery. Then leave it off for around 15 minutes then reinsert it and start the vehicle. This will reset the system and allow it to accept the key again.
The security light is the car immobiliser's method of letting you know that there's an issue with the system. If the light is illuminated and you attempt to start your car, it is a sign that the code that is stored in the ECU does not match the chip inside the key. This can happen if you have recently replaced your car key with a different one that was not programmed to the vehicle or in the event that you've had a defective swapped ECU.
If this is the case it is recommended to take your key or transponder chip to a professional to have them correctly programmed for the vehicle you are driving. It's possible that your 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 the ON position but don't try to start the engine. Let the key remain in this position for ten minutes. The security light should come on, then go off. If it does not then you must repeat this procedure and wait for another 10 minutes. Repeat this three times, and the issue should be solved.
Programming
The car immobiliser stops the engine from running if a key or fob is not properly programmed. It is based on a specific RFID microchip that isn't able to be duplicated and has its own digital serial number. The immobiliser will disengage in the event that it doesn't recognize the code. It's difficult to beat.
Modern cars come with this security system in the standard configuration. This makes it extremely difficult here to wire a car or use a different key as a starter. The system works by checking the chip in the key fob or a key and sending a passcode to the ECU (electronic control unit). The ECU will then verify that it's the right key and that the code isn't compromised. The system will not allow the car to start if the doesn't have the correct code, and some models will even notify the owner if someone tries to use a wrong 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 wire in a get more info vehicle to fool the ECU. This is a risky technique and requires more info a lot of expertise to avoid electrocuting yourself. Plus, a lot of modern car thieves have moved to more sophisticated methods such as using specialised apps or Bluetooth to hijack the car's information and remotely control it via their mobile.
Owners of cars will often see warning lights that indicate an immobiliser malfunctioning. It can happen for various reasons but the most frequent one is a faulty battery in the keyfob. This problem can be fixed by replacing the battery.
If this does not work it could be because the transponder chip is faulty or the ECU is mismatched. This is harder to fix and diagnose as it could require a professional 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 issues occur, it's recommended to visit an auto garage or a local dealer to seek assistance.
