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 won't start after inserting the key fob there may be a problem with the transponder chip not transmitting a security code to the immobilizer system.
This is a simple fix that any auto key fob repair locksmith on the Gold Coast can do. Let's take a look at the different elements of your car's immobiliser and what you can do to get it fixed.
Battery
It is important that you concentrate on the revenue and cost-savings opportunities that your auto repair shop. One way to do this is to offer key fob replacement and reprogramming services to your customers. This will not only benefit your customers, but also increase the profits of your shop without having sublet the dealership.
The key fob battery powers the remote locking and opening systems. However, it doesn't supply power to the immobiliser. Instead, the immobiliser relies on the transponder chip located on the fob or key. The chip transmits a passcode from the fob or key to the immobilizer unit in the car, which can be integrated into the PCM (power control module) BCM (brake control module for brake control), instrument clusters, smart junction boxes, or standalone modules. The system examines the code to ensure it is correct. If the code is incorrect the system will disable components that are crucial to starting the car, such as the starter motor or ignition. This will make the car almost impossible to start without the correct key.
Since its inception the immobiliser has proved to be an extremely effective tool in reducing the theft of cars. Even so the thieves are always looking for ways to circumvent these security measures. One of these strategies is the Kia Challenge trend on TikTok that shows how simple it is to connect hot wires to an vehicle.
Most insurance companies now factor in the use of an immobiliser in calculating premiums, making it more attractive to purchase a car that already has this feature. Even vehicles that are factory fitted with an immobiliser could be prone to problems. Fortunately, these issues are usually easy and cheap to repair car key fob. A dying or dead keyfob battery is usually the reason for a malfunctioning ignition immobiliser. A quick diagnostic test could identify the issue. If the issue continues, it could be due to electrical issues or wiring issues. If this is the case, it's best to have a professional diagnose and fix the problem.
Transponder Chip
In cars made after 1995, a tiny electronic chip referred to transponder is embedded in the head of your car key. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose 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 that signal sent from the key, it will disarm the immobiliser and allow the engine to begin.
The key with the transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than a mechanical key. It is possible to duplicate a traditional key, but not a transponder one. Contrary to the central locking element remote of a conventional key, which uses battery power, a transponder chip powered by an infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder has to be switched to ON. The ring emits IR energy that is picked up by a microchip in the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer compared the code in its memory to the one from the transponder chip and when they match the engine will be able to start.
If the immobiliser is able to detect an unauthorised transponder, key or other device is in use it will shut down the engine and prevent any of its essential components from functioning. The car will not move in the event that the engine is not functioning. It's easy for criminals to wire it and then drive off. This is an effective deterrent to crime, and is the reason why you should get your car key-immobiliser repaired promptly in the event of a malfunction. If you don't fix it, the security light on your vehicle will continue to flash and it will be difficult to start your engine.
Security Light
The immobiliser is powered by a small battery that sends an electric signal to the transponder chip inside your key. This is an anti theft device that blocks anyone from starting your car without the correct key. If the system cannot detect a digital serial number from the chip on your key, it will disable the engine immobiliser, which will stop the car from starting.
The car immobiliser system is an an effective way to stop thieves but sometimes it can get out of connection with the key or the transponder chip. This could be due to interference or the system becoming too sensitive. This could require a reset. To do this simply disconnect the battery. Leave it disconnected for about 15 minutes then reinsert it and begin the car. This will reset the key system so that it is ready to accept your keys once again.
The security light is an immobiliser's way of alerting you to the presence of a problem. If you attempt to start the car key fob repairs and the light stays on, it means that the chip inside your key doesn't match the code that is stored in the ECU. This can happen if you have recently replaced your car key with a different one that isn't programmed to the vehicle or if you've had a bad swapped ECU.
If this is the case you should take your transponder or key chip to a professional to get them properly programmed for your car. There is also the possibility that the system is not accepting the key due to an update or software issue. To test this, insert your key into the ignition and turn the ON position. Don't try to start the car. The key should remain in this position for ten minutes. The security light should come on, then turn off. If it doesn't, you'll need to repeat the procedure and wait another 10 minutes. Repeat the process three times and the problem is likely to be solved.
Programming
The car immobiliser stops the engine from running if a key or fob is not programmed correctly. It uses a special RFID chip that cannot be copied and is equipped with a digital serial number. The immobiliser will disconnect in the event that it is unable to recognize the code. That's why it's difficult to beat.
Modern cars have this system as standard. This makes it extremely difficult to wire the car hot or use a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU recognizes that it is the correct key and that there hasn't be compromised 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 incorrect fob or key.
However it isn't foolproof. Certain thieves have been able to bypass the immobiliser by using techniques like 'hot-wiring'. This involves crossing the wrong wire in an automobile to trick the ECU. However, this method is extremely risky and requires a great deal of knowledge of how to accomplish it without damaging yourself. Plus, a lot of modern car thieves have switched to more sophisticated methods like using specialized apps or Bluetooth to steal a car's data and remotely control it via their mobile.
Car owners often see warning lights that indicate the immobiliser is malfunctioning. This could be due to many reasons however the most common reason is a defective battery in the keyfob. A simple replacement should fix this issue.
If this doesn't work the transponder chip could be defective or mismatched with the ECU. This is harder to determine and fix since it may require a specialist locksmith or dealership. However, a car's immobiliser may also be damaged by water intrusion or even being removed from the fob or key. If you experience any of these problems it is a great idea to visit the local car dealer or garage where to repair car key remote (Ai-db.science) seek help.
