Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Currently, most vehicles come equipped with an engine immobilizer to stop car theft. If your vehicle won't start after inserting the key fob there could be a problem with a transponder chip that is not transmitting a security code to the immobiliser system.
This is a straightforward fix for any auto locksmith in Gold Coast. Let's examine the different components of your car immobiliser and what you can do to fix it.
Battery
If you are in the auto repair business it is essential to be aware of your shop's earnings and cost-saving opportunities. You can do this by providing key fob replacements and reprogramming for your customers. This will not only assist your customers but also add to the profits of your business without having to sublet to the dealership.
Typically the battery for the key fob powers the remote locking and opening systems. However, it doesn't supply power to the immobiliser. Instead, the immobiliser is dependent on the transponder chip in the fob or key. The chip transmits a passcode from the fob or key to the immobilizer unit of the car, which can 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 examines the code to make sure it is correct. If it is not it is, the system will shut down parts that are essential to start the vehicle, such as the starter motor or ignition. This will make the vehicle nearly impossible to start without the right key.
Since its introduction, the immobiliser has been an extremely effective tool for decreasing car theft. Even so, thieves are constantly looking for ways to circumvent these security measures. One of these is the Kia Challenge trend on TikTok that shows how simple it can be to hot-wire an vehicle.
Insurance companies are now factoring the use of an immobiliser in calculating premiums. This makes it more appealing to buy a car with this feature. Even vehicles that are factory fitted with an immobiliser could be prone to problems. These issues are typically simple and cheap to fix. Most of the time the issue is the result of an inactive or dead key fob battery. A quick diagnostic test will reveal this issue. If the issue persists, it could be due to electrical problems or wiring issues. If this is the case, it's best to have a professional diagnose and repair the issue.
Transponder Chip
A small electronic chip, also known as transponder, is incorporated inside the head portion of your car keys. This technology was first introduced in cars made after 1995. Also known as a chip key or a 'transmitter & responder key, it is designed to prevent the engine from starting if a third party has an exact copy of your car key. It works by transmitting an audio signal from the key to your immobiliser system. If the code stored in the car's computer is in line with the signal sent by the key, the immobiliser will be removed and the engine will start.
The key that is equipped with a transponder chip is sometimes called a 'fob' or a smart key due to the fact that it is more difficult to copy than a traditional mechanical key. It is possible to duplicate a conventional key, but not a transponder key. Transponder chips are powered by an infrared signal and not battery power.
To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits IR energy that is received by a microchip inside the key. The chip then sends a unique code to the immobiliser inside your car. The car's computer compared the code in its memory to the one from the transponder chip, and if they match the engine will be able to start.
The immobiliser shuts down the engine when it detects an unauthorized key or transponder. It will also prevent any essential components of the vehicle from functioning. Without a functioning engine, the car will not be able to move, and it would be very easy for a criminal to wire the vehicle and then drive off. This is an effective deterrent to criminals, which is why you must have your car's key-immobiliser repaired promptly if it develops a fault. If you don't do this, the security light in your car will continue to flash and it will be inaccessible for you to start your engine.
Security Light
The immobiliser utilizes a small battery to transmit an electrical signal to the chip inside your key. This anti-theft device prevents anyone from starting their car without the correct keys. If the system is not able to recognize an electronic serial number from the chip on your key, it will shut off the engine immobiliser to stop the car from starting.
This car immobiliser system is effective in stopping thieves, but it is also possible for it to be out of connection with the key or transponder chip. This can be due to interference or the system is too sensitive. This may need an adjustment. To do this, just disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and start 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 key repair service with the system. If the light is on when you attempt to start your car, it means that the code that is stored in the ECU is not compatible with the chip inside the key. This can happen when your car's key has been replaced with a new one that is not programmed for the vehicle, or if an ECU was swapped in a wrong manner.
If this is the situation, it's best to bring your transponder key or chip to a professional to get them properly programmed for your car. 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. The key should remain in this position for 10 minutes. The security light should come on, then go off. If it doesn't, you will need to repeat the procedure and wait another 10 minutes. Repeat the process three times, and the issue should be solved.
Programming
A car immobiliser prevents a car's engine from running without a properly programmed key or fob. It utilizes a specific RFID chip that is unable to be copied and has a digital serial number. The immobiliser will be disengaged if it doesn't recognise the code. That's why it's so difficult to defeat.
Modern cars come with this system as standard. This makes it really hard to wire the car hot or use a different key as a starter. The system works by checking the chip in the key fob or key, and sending a passcode to the ECU (electronic control unit). The ECU is aware that it's the right key and hasn't been a compromise in the code. The system won't allow the car to start if it does not receive the correct code, and some models will even report back to the owner if a person tries to use an incorrect fob or key.
However it isn't foolproof. Some thieves have managed to bypass the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wire in a vehicle in order to cause a malfunction in the ECU. However, this method is pretty risky and requires a great deal of experience to accomplish it without electrocuting yourself. In addition, many modern car thieves have switched over to more advanced methods such as using specialised apps or Bluetooth to take over the car's data and then remotely control it from their phones.
Car owners are often faced with warning lights that indicate the immobiliser has gone haywire. This can happen for various reasons, but one of the most frequent causes is a faulty or dead battery on the key fob. This issue can be resolved by a simple replacement.
If this doesn't work the transponder chip could be defective or mismatched with the ECU. It is more difficult to determine and fix because it requires a specialist car locksmith or dealership. However, a car immobiliser can also be damaged due to water ingress or even physically being pulled away from the fob or key. If any of these problems occur, it's recommended to visit the nearest garage or dealer for assistance.
