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 could be an issue with the transponder chip not transmitting an encryption code to the immobilizer system.
This is a quick 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 fix it.
Battery
It is essential to focus on the revenue and cost-savings opportunities of your auto repair shop. One way to do this is to provide key fob replacement and reprogramming to your customers. This will not only benefit your customers but will also boost your shop's profit, without having sublet the dealership.
Typically the key fob battery powers the remote locking and opening systems. However, it doesn't power the immobiliser. Instead, the immobiliser depends on the transponder chip that is located in the key or fob. The chip transmits a passcode to the car's immobilizer device that can be integrated into the PCM, BCM or instrument cluster smart junction box or standalone module. 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. The car will be impossible to start if the driver doesn't have the correct key.
The immobiliser system has proven highly effective in decreasing car theft since its first introduction. However it is not uncommon for thieves to look for new ways to get around these security measures. One of these is the Kia Challenge trend on TikTok that demonstrates how easy it is to wire an automobile.
The majority of insurance companies now factor in the use of an immobiliser when they calculate premiums, making it more appealing to purchase an automobile that has this feature. Even vehicles that are factory-fitted with an immobiliser could have issues. These issues are typically simple and affordable to fix. Most of the time an immobiliser that is not working properly is caused by a dead or dying key fob battery. This can be determined by an easy diagnostic test. If the problem persists it could be due to other causes of the car's irregular behavior, such as electrical problems or a wiring issue. If this is the case, it's recommended to have a professional diagnose and repair the problem.
Transponder Chip
A tiny electronic chip, referred to as transponder, is embedded into the head portion of your car keys. The technology was introduced in vehicles manufactured after 1995. It is also referred to as a "chip key" or a "transmitter-responder" key. Its purpose is to stop the engine from starting when you have an identical key. It works by transmitting a radio frequency from the key to your immobiliser. If the code stored in the computer of the car matches the signal transmitted by the key the immobiliser will be disarmed and the engine will be able to start.
The key with the transponder can also be referred to as a "fob" or a "smart" key, because it is more difficult to copy than a mechanical key. Using specific techniques, it is possible to copy a standard car key, but not transponder keys. Unlike the remote central locking element of a standard key which uses battery power, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits a flash of IR energy which is picked up by the microchip within the key. The chip then responds with an individual code to the immobiliser of your car. The computer in the car analyzes the code stored in its memory to the one on the transponder and If the two codes are identical it will begin the engine.
The immobiliser will disable the engine if it detects an unauthorised transponder or key. It also stops all vital components of the vehicle from functioning. The car won't move in the event that the engine is not working. It would be easy for a criminal hot-wire it to drive away. This is a powerful deterrent to crime and it is one of the reasons why it's essential to have your car's key immobiliser fixed immediately you discover a fault with it. If you don't do this, the security light on your car will keep flashing and it will be inaccessible to start your engine.
Security Light
The immobiliser makes use of a tiny battery to transmit an electrical signal to the chip inside your key. This anti-theft device stops anyone from starting the car if they don't have the correct keys. If the system cannot detect a digital serial from the chip in your key, it will disable the engine immobiliser to stop the car from starting.
The car immobiliser is a great method of deterring thieves, but it can sometimes get out of the sync. This can be due to interference or the system becoming too sensitive. If this is the case, it may need to be reset. To do this, just disconnect the battery. Then leave it off for around 15 minutes before reinstalling it and begin the vehicle. This will reset the key system to ensure that it is ready to accept your keys once again.
The security light is an immobiliser's method of alerting you to a problem. If you try to start the car and the light stays on, it means that the chip in your key doesn't match the code that is stored in the ECU. This can happen if you have recently replaced the car key with a different one that was not programmed to your vehicle or when you've had a damaged swapped ECU.
If this is the situation, then it's time to go to a professional and have the transponder or key chip properly programmed to your vehicle. There is also the possibility that the system is not accepting the key because of a software bug or update. To test this, place your key in the ignition and turn it to ON but don't try to start the engine. Keep the key in this position for ten minutes. The security light should turn on, then turn off. If it doesn't then you'll need to repeat the procedure and wait another 10 minutes. This should solve the problem If you repeat the procedure three times.
Programming
The car immobiliser stops the engine from running when a key or fob is not properly programmed. It uses a special RFID microchip that isn't able to be duplicated and has its own serial number. The immobiliser will disconnect in the event that it is unable to recognize the code. This is why it's so hard to beat.
Modern cars come with this security system as standard. This makes it difficult to wire a car or utilize a different key for starter. The system works by checking the chip in the key fob or key, and transmitting a passcode to the ECU (electronic control unit). The ECU is then able to determine that it's the correct key and that the code hasn't been compromised. The system will not allow the car to start if it does not receive the correct code. Some models will even report back to the owner in the event that someone attempts to use an unapproved fob or key.
The system isn't completely impervious to attack, but it is. Certain thieves have been able to bypass the immobiliser by using techniques like 'hot-wiring'. This involves crossing the wrong wires within the wiring of a vehicle, which fools the ECU into thinking that the proper key or fob is being used. But, this technique is quite risky and requires a great deal of knowledge of how to accomplish it without electrocuting yourself. Additionally, many modern car thieves have shifted to more sophisticated methods like using specialized apps or Bluetooth to hijack the car's data and then remotely control it via their phone.
Owners of cars will often see warning lights that indicate an immobiliser gone haywire. This could be due to a variety of reasons, but one of the most frequent is a dead or defective battery on the key fob. This problem can be fixed by an easy replacement.
If this does not work, it could be that the transponder chip is faulty or the ECU is mismatched. 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 you experience any of key repair car these issues it is a good idea to consult the local car dealer or garage for assistance.
