Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Today, the majority of vehicles are equipped with an engine immobilizer to prevent car theft. If your vehicle will not start after inserting the key fob it could be due to a problem with a transponder which isn't sending a security signal to the immobiliser.
This is a simple fix for any auto locksmith in Gold Coast. Let's look at the various components of your car immobiliser and what you can do to fix it.
Battery
It is essential to concentrate on the cost-savings and revenue opportunities of your auto repair shop. One way to do this is to offer key fob replacement and reprogramming to your customers. This will not only help your customers but also boost the profits of your business without having to sublet to 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 is dependent on the transponder chip that is located in the fob or key. The chip transmits a passcode 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 will check the code to make sure that it is correct. If the code isn't correct it will disable the elements that are crucial to the start of the car, such as the ignition or starter motor. This will make the car almost impossible to start if you don't have the right key.
Since its introduction the immobiliser has proved to be a very effective tool in reducing the theft of cars. However the fact that thieves are always looking for new ways to get around these security measures. One of these techniques is a recent trend known as the Kia Challenge on TikTok that showcased how easy it is to connect a vehicle with hot wires.
The majority of insurance companies now factor in the use of an immobiliser when they calculate rates, which makes it more appealing to shop for an automobile that has this feature. However, even cars equipped by the manufacturer with an immobiliser may experience problems with it. These problems are often easy and affordable to fix. A dying or dead keyfob battery is usually the cause of a faulty ignition immobiliser. A quick diagnostic test can uncover the problem. If the issue persists it could be due to other causes for the vehicle's misbehaviour, including electrical issues or a wiring problem. If this is the case, it's best to seek out a professional to diagnose and repair the issue.
Transponder Chip
In cars made after 1995, a small electronic chip, referred to as transponder is integrated into the head of your car key. It is also known as a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting when someone else has an identical key. It works by transmitting the radio frequency signal from the key to the immobiliser system in your car. If the code stored in the computer of the car is in line with the signal sent by the key the immobiliser will be disarmed and the engine will start.
The key that has the transponder chip can be referred to as a 'fob' or a "smart" key because it is much more difficult to clone than a traditional mechanical key. With the help of special techniques, it is feasible to duplicate a standard car key however, not transponder keys. 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 a burst of IR energy that is picked up by the microchip within the key. The chip responds by sending a unique code the immobiliser of your car. The computer in the car analyzes the code stored in its memory with the transponder's and if the two codes match it will begin the engine.
If the immobiliser detects that an unauthorised transponder, key or other device is in use, it will disable the engine and block any of its vital components from working. The car will not move when the engine isn't functioning. It's easy for a criminal hot-wire it and drive off. This is an effective deterrent to criminals, which is the reason why you should get your car's key-immobiliser fixed as quickly as possible if it develops a fault. If you don't do this, the security light on your car will keep flashing and it will be impossible for you to start your engine.
Security Light
The immobiliser uses a small battery to transmit an electrical signal to the chip in your key. It is an anti-theft device that stops anyone from opening your vehicle without the proper key. If the system is unable to detect a serial number digital from the chip in your key, it will disable the engine immobiliser, preventing the car from starting.
This car immobiliser system is effective in stopping thieves, but it is also possible for it to be out of sync with the key or transponder chip. This could be due to interference or the system becoming too sensitive. If this is the case it could be necessary to reset. To do this, simply disconnect the battery. After 15 minutes, you can reinstall the battery and then restart the car. This will reset the key system so that it is ready to accept keys once more.
The security light is an immobiliser's way of alerting you to an issue. If the light is illuminated and you try to start your vehicle, it indicates that the code that is stored in the ECU does not match the chip on the key. This can happen if you have recently replaced your car key with one that was not programmed to the vehicle or in the event that you've had a defective swapped ECU.
If this is the case, then you need to go to a professional and have the the transponder chip properly programmed to your vehicle. It is possible that the system won't accept the key because of a software update or glitch. To test, insert your key in the ignition and then turn it to the ON position. Don't try to start the vehicle. The key should remain in this position for ten minutes. This should cause the security light to turn on and to go off. If it doesn't work, you'll have to repeat the procedure and wait another 10 minutes. This should resolve the issue If you repeat the procedure three times.
Programming
A car immobiliser prevents the engine of a car from running without a correctly programmed key or fob. It is based on a specific RFID micro-chip that can't be copied and has its own serial car key and repair 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 are fitted with this security system as standard. This makes it very difficult to wire the car hot or use another key for starter. The system works by analyzing the chip inside a key fob or a key and sending a passcode to the ECU (electronic control unit). The ECU will then verify that it's the right key and that the passcode hasn't been compromised. The system won't allow the car to start if the does not receive the correct code, and some models will even report back to the owner in the event that someone attempts to use an incorrect key or fob.
However it isn't completely secure. Certain thieves have been able to get around the immobiliser using methods like hot-wiring. This involves using the wrong wiring in an automobile to fool the ECU. However, this is quite dangerous and requires a lot of knowledge of how to carry out the procedure without electrocuting yourself. Plus, a lot of modern car thieves have switched to more sophisticated methods like using specialized apps or Bluetooth to steal a car's data and remotely control it using their phone.
Owners of cars will often be greeted by warning lights that indicate an immobiliser gone haywire. It can happen for many reasons, but the most common one is a faulty battery in the keyfob. The issue can be solved by replacing the battery.
If this does not work it could be because the transponder chip may be defective or the ECU is mismatched. This is more difficult to fix and diagnose as it may require a specialist locksmith or dealership. A car's immobiliser can be damaged if water manages to enter the system or is physically removed from its fob or key. If any of these issues occur, it's a good idea to visit a local garage or car dealer for assistance.
