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 it could be a problem with a transponder that's not sending a security signal to the immobiliser.
This is a simple fix for any auto locksmith in Gold Coast. Let's take a look at the different parts of your car's immobiliser and what you can do to fix it.
Battery
If you are in the auto repair business, it is important to focus on your shop's revenue and cost-saving opportunities. You can achieve this by providing key fob replacements and reprogramming to your customers. This will not only benefit your customers but also increase the profits of your shop 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. Instead, the immobiliser relies on the transponder chip in the key or fob. The chip transmits a code from the key or fob to the immobilizer module of the car. It can be integrated into the PCM (power control module) or BCM (brake control module for brake control), instrument clusters, smart junction boxes, or standalone modules. The system then checks the code to ensure that it is correct. If it is not, the system will disable components crucial to starting the vehicle, like the ignition or starter motor. The car will be nearly impossible to start if you do not have the correct key.
The immobiliser has proven highly effective in cutting down on car theft since it was first introduced. Even so, thieves are constantly looking for ways to circumvent these security measures. One of these strategies is the Kia Challenge trend on TikTok that shows how simple it can be to hot-wire an automobile.
Insurance companies are now factoring the use of an immobiliser in calculating premiums. This makes it more attractive to buy a car with this feature. Even cars that are factory fitted with an immobiliser might be prone to problems. Fortunately, these issues are usually simple and inexpensive to fix. Most of the time the issue is the result of an inactive or dead key fob battery. A quick diagnostic test can reveal this issue. If the problem persists it could be due to other causes of the car's misbehaviour, including electrical issues or a wiring issue. It is best to have a professional diagnose the problem and fix it.
Transponder Chip
In cars made after 1995, a small electronic chip called transponder is embedded in the head of your car key. Also known as a 'chip key' or a 'transmitter and responder' key, it is designed to prevent the engine from starting if another person has the same key. It works by sending an audio frequency signal from the key to the immobiliser system in your car. If the code stored in the car's computer is in line with the signal from the key, it will disarm the immobiliser and allow the engine to begin.
The key with the transponder chip is sometimes called"fob" or a 'smart' key due to the fact that it is more difficult to duplicate than a traditional mechanical key. It is possible to duplicate a conventional key but not a transponder one. Contrary to the remote central locking element of a standard key which is powered by batteries, a transponder chip is powered by an infrared (IR) signal that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip, the ignition cylinder must be turned on. The ring emits a flash of IR energy that is detected by the microchip within the key. The chip responds by transmitting a unique code to the immobiliser of your car. The car's computer checks the code in its memory with the one from the transponder chip and when they match the engine will begin to rev.
If the immobiliser detects an unauthorised transponder, key or other device is being used it will shut down the engine and block any of its vital components from functioning. Without a functioning engine, the vehicle will not be able to move and it could be easy for criminals to hot-wire the vehicle and drive away. This is an effective deterrent to crime, and is why you must have your car's key-immobiliser fixed as quickly as possible in the event of a malfunction. If you don't do this, the security light on your car will keep flashing and it will be inaccessible for you to start your engine.
Security Light
The immobiliser utilizes a small battery to send an electrical signal to the chip inside your key. This is an anti theft device that blocks anyone from driving your car without the correct key. If the system is not able to recognize a digital serial from the chip in your key, it will shut off the engine immobiliser to prevent the car from starting.
This system for car immobilisation is an an effective way to stop thieves, but it is also possible for it to become out of sync with the key or transponder chip. This could be due to interference or the system is too sensitive. This may require a reset. To do this, just disconnect the battery. After 15 minutes, reconnect the battery and restart the vehicle. This will reset the system and allow it to accept the key again.
The security light is an immobiliser's way of alerting you to the presence of a problem. If you try to start your car and the light is solid on it means that the chip in your key isn't compatible with the code that is stored in the ECU. This can happen when your car's key has been replaced by an alternative key that is not programmed to work with the vehicle, or if an ECU was not swapped correctly.
If this is the situation you should take your transponder or key chip to a professional to get them properly programmed for your car. It's possible that the system will not accept the key due to a software upgrade or bug. To test this, insert your key into the ignition and turn the ON position. Do not attempt to start the vehicle. Let the key stay in this position for 10 minutes. This will cause the security light to come on and then to go off. If it doesn't work, you'll have to repeat the process and wait another 10 minutes. Do this three times and the issue is likely to be solved.
Programming
A car immobiliser prevents the engine of a car from running without a key that is programmed correctly or fob. It is based on a specific RFID microchip that isn't able to be duplicated and comes with its own digital serial number. The immobiliser will stop working in the event that it is unable to recognize the code. It's tough to beat.
Modern cars are fitted with this security system as standard. This makes it really hard to connect the car to a hot wire or use another key for starter. The system works by analyzing the chip in the key fob or key and sending a passcode back to the ECU (electronic control unit). The ECU knows it's the correct key and that there hasn't been a compromise in the code. The system won't allow the car to begin if it does not receive the correct code. Some models even notify the owner when they attempt to use a wrong fob or key.
The system is not impervious to attack, but it is. Some thieves have managed to bypass the immobiliser by using techniques like 'hot-wiring'. This involves crossing the wrong wires through a vehicle's wiring to fool the ECU into thinking the correct key or fob is being used. However, this method is pretty risky and requires a lot of knowledge of how to do it without damaging yourself. Additionally, many 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 from their mobile.
Owners of cars will often notice warning lights that signal an immobiliser that has gone out of control. This could be due to various reasons however the most common reason is a defective battery in the keyfob. The issue can be solved by an easy replacement.
If this does not work, it could be that the transponder chip is defective or the ECU is not compatible. This is more complicated to fix and diagnose, as it can involve a specialist locksmith for cars or a dealership. However, a car's immobiliser may 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 a local car car key fob repair near me dealer or garage for assistance.
