Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Most cars are equipped with an immobilizer that prevents car theft. If your vehicle doesn't start after inserting the key fob, there may be a problem with a transponder chip that is 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 parts of your vehicle immobiliser to discover what you can do.
Battery
It is essential to focus on the cost-savings and revenue potentials of your auto repair shop. You can accomplish this by providing key fob replacements and reprogramming to your customers. This will not only help your customers but also add to the profits of your shop without subletting to the dealership.
Typically, the key fob battery powers the remote opening and locking systems. However, it doesn't supply power to the immobiliser. The immobiliser is powered through the transponder located in the fob, key or instrument cluster. This chip sends a passcode to the car's immobilizer device which can be integrated into the PCM, BCM, the instrument cluster smart junction box, or standalone module. The system then verifies the code to make sure it is correct. If it's not it is, the system will shut down components crucial to starting the vehicle, like the ignition or starter motor. The car will be impossible to start if the driver doesn't have the correct key.
The immobiliser system has been highly effective in reducing car theft since its introduction. Despite this it is not uncommon for thieves to look for new ways to get around these security measures. One of these methods is the Kia Challenge trend on TikTok that shows how simple it can be to hot-wire an vehicle.
Insurance companies are now incorporating the use of an immobiliser to calculate premiums. This makes it more attractive to purchase a vehicle with this feature. However, even cars that came factory-fitted with an immobiliser can experience issues with it. These issues are typically simple and cheap to fix. A dead or dying keyfob battery can be the cause of a malfunctioning ignition immobiliser. A quick diagnostic test will reveal this issue. If the issue persists it could be due to other causes for the vehicle's irregular behavior, such as electrical problems or a wiring issue. If this is the case, it's best to have a professional diagnose and fix the issue.
Transponder Chip
In cars made after 1995, a small electronic chip, referred to as transponder is embedded in the head of your car key. 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 a duplicate of your key. It works by transmitting a radio frequency from the key to the immobiliser system. If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will be disarmed and the engine will start.
The key that has a transponder can also be referred to as a "fob" or a "smart" key, because it is more difficult to copy than mechanical keys. It is possible to duplicate a standard key but not a transponder key. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder chip the ignition cylinder must be turned to the ON position. The ring emits IR energy which is received by a microchip within the key. The chip then responds with a unique code to the immobiliser inside your car. The car's computer compared the code in its memory with that from the transponder chip and If they are compatible the engine will begin to rev.
If the immobiliser detects that an unauthorised transponder, key or other device is in use it will shut down the engine and block any of its essential components from working. Without a functioning engine, the vehicle will not be able to move, and it will be easy for criminals to connect the vehicle to a hot wire and then drive away. This is a powerful deterrent to criminals and is one of the main reasons why it's essential to have your car's key immobiliser repaired when you spot a fault with it. If you don't do this, the security light on your vehicle will continue blinking, and you won't be able to start it.
Security Light
The immobiliser is powered by a small battery that transmits an electrical signal to the transponder chip inside your key. This is an anti-theft device that prevents anyone from starting your vehicle without the proper key. If the system is unable to detect a serial number digital from the chip inside your key it will disengage the engine immobiliser and stop the car from starting.
This system for car immobilisation is an an effective way to stop thieves, however it can get out of connection with the key or the transponder chip. This can be caused by interference or the system becoming too sensitive. This may require a reset. To do this, just disconnect the battery. After 15 minutes, reinstall the battery and restart the car. This will reset the key system, so that it is ready to accept your keys 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 and the light is solid on it means that the chip inside your key isn't compatible with the code stored in the ECU. This could happen if have recently replaced your car key with a different one that was not programmed to the vehicle or if you've had a bad swapped ECU.
If this is the case then you need to go to a professional for assistance and get the transponder or key chip properly programmed to your vehicle. It's possible that your system won't accept the key due to a software update or glitch. To test this put your key in the ignition and switch it to ON but don't attempt to start the engine. Keep the key in this position for 10 minutes. The security light should turn on, and then go off. If it doesn't then you'll have 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 if a key or fob is not properly programmed. It uses a special RFID chip that can't be copied and has a digital serial number. The immobiliser will disconnect if it does not recognise the code. That's why it's difficult to beat.
Modern cars come with this security system as standard. This makes it extremely difficult to wire the car hot or use a different key for starter. The system works by analyzing the chip inside the key fob or a 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 passcode isn't compromised. The system won't allow the car to begin if it does not receive the correct code. Some models even inform the owner when they attempt to use a wrong fob or key.
However it isn't foolproof. Certain thieves have been able to bypass the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wires within the wiring of a vehicle to trick the ECU into thinking the appropriate fob or key is being used. However, this is quite dangerous and requires a car key repair lot of experience in order to accomplish it without electrocuting yourself. In addition, many modern car thieves have moved to more sophisticated methods, such as using specialized apps or Bluetooth to take over a car's data and remotely control it from their phone.
Car owners often see warning lights that indicate an immobiliser gone haywire. It can happen for various reasons but the most frequent reason is a defective 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 may be defective or the ECU is not matched. This is more difficult to diagnose and fix as it could require a professional locksmith or dealership. The car immobiliser could also be damaged if water is able to get into the system or is physically removed from its fob or key. If any of these issues occur, it's a good idea visit an auto garage or a local dealer for assistance.
