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 will not start after inserting the key fob, it could be an issue with a transponder that's not sending a security message to the immobilizer.
This is a simple fix that any auto locksmith on the Gold Coast can do. Let's examine the different parts of your car's immobiliser and what you can do to fix it.
Battery
It is crucial to concentrate on the profit and cost-saving opportunities of your auto keyless entry repair shop. One method to achieve this is to offer key fob replacement and reprogramming services to your customers. This will not only benefit your customers but also increase your shop's profits without having to sublet to the dealership.
The key fob battery is used to power the remote locking and opening systems. However, it does not supply power to the immobiliser. Instead, the immobiliser relies on the transponder chip located in the key or fob. This chip transmits a code to the car's immobilizer device, which may be built into the PCM, BCM or instrument cluster smart junction box or standalone module. The system 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. This will make the car almost impossible to start without the right key.
The immobiliser has proven extremely effective at reducing car theft since it was first introduced. However, thieves are always looking for new ways to circumvent these security measures. One of these strategies is a recent trend called the Kia Challenge on TikTok that showed how easy it was to wire a vehicle.
Insurance companies are now incorporating 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 might be prone to problems. Fortunately, these issues are usually straightforward and affordable to fix. The majority of the time an immobiliser that is not working properly is caused by a dead or dying key fob battery. A quick diagnostic test will identify the issue. If the issue continues, it could be due to electrical issues or wiring issues. It is best to let a professional identify the issue and then solve it.
Transponder Chip
A tiny electronic chip, also known as transponder, is embedded inside the head portion of your car keys. The technology was introduced in vehicles manufactured after 1995. It is also known as a "chip key" or a "transmitter-responder" key. Its goal is to prevent the engine from starting when another person has an identical key. It works by transmitting an audio frequency signal from the key fob repair service to the immobiliser system in your car. If the code stored in the computer of the car matches the signal sent by the key, the immobiliser will be deactivated and the engine will be able to start.
The key that is equipped with a transponder chip can be referred to as"fob" or a 'smart' key because it is much more difficult to copy than a conventional 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 powered by the infrared (IR) signal that is transmitted by the antenna ring on the ignition cylinder.
To activate the transponder the ignition cylinder must be in the ON position. The ring emits a blast of IR energy which is absorbed by the microchip in the key. The chip responds by sending a unique code to the immobiliser of your car key repair. The car's computer checks the code stored in its memory with that from the transponder chip and If they are compatible the engine will begin to rev.
If the immobiliser is able to detect an unauthorized transponder or key is being used it will shut down the engine and stop any of its essential components from working. Without a functioning engine, the vehicle will not be able to move, and it would be very easy for a criminal to hot-wire the vehicle and then drive off. This is a great deterrent to crime, and is why you should have your car key-immobiliser repaired as quickly as possible if it develops a fault. If you don't fix it, the security light in your car will keep flashing and it will be difficult for you to start your engine.
Security Light
The immobiliser utilizes a small battery to transmit an electrical signal to the chip that is in your key. This anti-theft device prevents anyone from starting the car without the proper keys. If the system cannot detect a digital serial from the chip in your key, it will disable the engine immobiliser, which will stop the car from starting.
The car immobiliser is a great method of deterring thieves, however it can occasionally be out of in sync. This could be due to interference or the system becoming too sensitive. This could need a reset. To do this, disconnect the battery. After 15 minutes, reconnect the battery and restart the vehicle. This will reset the key system, so that it is ready to accept keys once more.
The security light is an immobiliser's method of alerting you to an issue. If the light is illuminated and you try to start your car, it is a sign that the code that is stored in the ECU does not match the chip inside the key. This could happen if have recently replaced your car key with another that was not programmed to the vehicle or if you've had a bad swapped ECU.
If this is the situation, it's best to take your key or transponder chip to a professional for them properly programmed for your car. It is possible that the system will not accept the key because of a software update or bug. To test this, place 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. This will cause the security light to light up and then to go off. If it doesn't, you'll need to repeat the procedure and wait another 10 minutes. Repeat this three times, and the issue is likely to be solved.
Programming
The car immobiliser stops the engine from running if a key or fob is not properly programmed. It makes use of a unique RFID microchip that cannot be duplicated and comes with its own digital serial number. The immobiliser will stop working in the event that it doesn't recognize the code. It's hard to beat.
Modern cars are equipped with this security 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 analyzing the chip in a 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 that there hasn't be compromised code. The system won't allow the car to begin in the event that it does not receive the correct code. Some models even notify the owner if they attempt to use an incorrect fob or key.
The system isn't foolproof, however. Some thieves have gotten around the immobiliser using methods such as 'hot-wiring.' This involves crossing the wrong wiring in a vehicle in order to cause a malfunction in the ECU. But, this technique is quite risky and requires a lot of experience in order to carry out the procedure without damaging yourself. In addition, many modern car thieves have moved over to more advanced methods, such as using specialized apps or Bluetooth to steal a car's data and remotely control it from their mobile.
Car owners will frequently be greeted by warning lights that indicate an immobiliser gone haywire. It can occur for a variety of reasons, but the most frequent is a dead or defective battery in the key fob. This issue can be resolved by a simple replacement.
If this does not work it could be because the transponder chip is faulty or the ECU is not matched. This is more complicated to determine and fix, as it can involve an expert locksmith for cars or a dealership. However, a car immobiliser can also be damaged due to water ingress or even physically being removed from the fob or key. If you encounter any of these problems it is a good idea to visit the local car dealer or garage for assistance.
