Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Currently, most vehicles come equipped with an engine immobilizer to protect against theft of cars. If your vehicle doesn't start after inserting the key fob there could be an issue with a transponder chip that is not sending an authorization 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 car's immobiliser and what you can do to fix it.
Battery
It is crucial to focus on the cost-savings and revenue potentials of your auto repair shop. One method to achieve this is to provide key fob replacement and reprogramming services to your customers. This will not only benefit your customers but will also increase the profits of your business without having to sublet to the dealership.
Typically the key fob battery powers the remote locking and opening systems. The immobiliser is not powered by the battery in the key fob. Instead, the immobiliser relies on the transponder chip on the fob or key. The chip transmits a code from the key or fob to the immobilizer unit in the car, which can be integrated into the PCM (power control module), BCM (brake control module for brake control), instrument cluster smart junction boxes or standalone modules. The system examines the code to ensure that it is correct. If the code isn't correct the system will disable components that are essential to the start of the car, such as the ignition motor or starter motor. This makes the car almost impossible to start without the correct key.
The immobiliser system has been extremely effective in cutting down on car theft since it was first introduced. However thieves are always looking for ways to circumvent these security measures. One of these techniques is an upcoming trend called the Kia Challenge on TikTok that showcased how easy it is to wire a vehicle.
The majority of insurance companies now factor in the use of an immobiliser when calculating premiums, making it even more appealing to shop for a car that already has this feature. However, even vehicles that were factory-fitted with an immobiliser can experience problems with it. Fortunately, these problems are usually simple and inexpensive to solve. A dead or dying keyfob battery is usually the reason for a malfunctioning ignition immobiliser. A quick diagnostic test could uncover the problem. If the issue continues to persist and continues to recur, there could be other reasons for the car's misbehaviour, including electrical issues or a wiring problem. It is recommended to let a professional identify the issue and then repair it.
Transponder Chip
A tiny electronic chip, referred to as a transponder, is built into the head portion of your car keys. This technology was introduced in vehicles manufactured after 1995. Also referred to as a 'chip key' or a 'transmitter and responder key, it's designed to stop the engine from starting if someone else has a copy of your car key. It functions 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 transmitted by the key, it will disable the immobiliser and allow the engine to begin.
The key that has a transponder is also referred to as a "fob" or a "smart" key, as it is more difficult to duplicate than a mechanical key. Using special methods, it is possible to copy a standard car key, but not the transponder key. Unlike the central locking element remote of a conventional key which uses battery power, 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 needs to be turned to the ON position. The ring emits a burst of IR energy, which is detected by the microchip within the key. The chip then sends a unique code to the immobiliser inside your car. The computer in the car examines the code in its memory with the transponder's code electronic car key repair and if the two codes match it will begin the engine.
If the immobiliser is able to detect an unauthorised transponder, key or other device is in use, it will disable the engine and prevent the essential components from working. Without a functioning engine the car will not be able to move and it could be easy for criminals to hot-wire the vehicle and then 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 repaired as soon as you notice a fault with it. If you don't do this, the security light in your car will keep flashing and it will be difficult to start your engine.
Security Light
The immobiliser makes use of a tiny battery to transmit an electrical signal to the chip in your key. This anti-theft device stops anyone from starting the car without the proper keys. If the system cannot detect an electronic serial number 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 effective in stopping thieves but sometimes it can get out of sync with the key or transponder chip. This can be due to interference or the system being too sensitive. If this is the case it could be necessary to reset. To do this, disconnect the battery. Leave it disconnected for about 15 minutes, then insert it and start the vehicle. This will reset the key system, so that it is ready to accept your keys again.
The security light is an immobiliser's method of warning you of the presence of a problem. If you try to start your car and the light stays on, it indicates that the chip inside your key doesn't match the code stored in the ECU. This could happen if your car key has been replaced with an alternative key that is not programmed for the vehicle, or if the ECU was swapped in a wrong manner.
If this is the situation, it's best to take your key or transponder chip to a professional to get them properly programmed for your vehicle. There is also the possibility that the system isn't accepting the key due to a software bug or update. To test this, place your key in the ignition and switch it to ON but don't attempt to start the engine. The key should remain in this position for 10 minutes. This should cause the security light to come on and then to turn off. If it does not, you will need to repeat the procedure and wait for another 10 minutes. This should resolve the issue If you repeat the procedure three times.
Programming
The car immobiliser blocks the engine from running if a key or fob is not properly programmed. It is a unique RFID chip that is unable to be copied and is equipped with a digital serial number. The immobiliser will disengage in the event that it doesn't recognize the code. It's hard to beat.
Modern cars come 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 operates by sending a passcode from the key fob to the ECU. The ECU is then able to determine that it's the correct key and that the passcode hasn't been compromised. The system will not allow the car to start in the event that it does not receive the correct code. Some models even notify the owner if they attempt to use a wrong fob or key.
The system isn't completely 100% secure, however. Certain thieves have been able to get around the immobiliser using methods like hot-wiring. This involves crossing the wrong wiring in a vehicle in order to fool the ECU. However, this is pretty risky and requires a great deal of experience in order to carry out the procedure without damaging yourself. Additionally, many modern car thieves have switched over to more advanced methods like using specialized apps or Bluetooth to take over the car's information and remotely control it from their phone.
Car owners are often faced with warning lights that indicate the immobiliser has gone off the rails. This could be due to a variety of reasons, but the most frequent is a faulty or dead battery in the key fob. This issue can be resolved by replacing the battery.
If this doesn't work it could be because the transponder chip may be defective or the ECU is not compatible. This is more difficult to determine and fix since it may require an expert locksmith or a dealership. A car's immobiliser can be damaged if water is able to get into the system, or if it is physically pulled away from its fob or key. If any of these issues occur it's a good idea to visit the nearest garage or dealer to seek assistance.
