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 doesn't start after inserting the key fob there could be an issue with a transponder chip that is not sending an encryption code to the immobiliser system.

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

The key fob battery powers the remote locking and opening systems. However, it does not supply power to the immobiliser. Instead, the immobiliser depends on the transponder chip that is located on the fob or key. The chip transmits a passcode from the key or fob to the immobilizer module of 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 make sure it's correct. If it is not then the system will disable elements that are crucial to the start of the vehicle, like the starter motor or ignition. The car will be nearly impossible to start if the driver doesn't have the correct key.

Since its introduction the immobiliser has proved to be a very effective tool in reducing the theft of cars.

Transponder Chip


A small electronic chip, referred to as a transponder, is built into the head portion of your car keys. The technology was introduced in vehicles manufactured after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to stop the engine from starting when you have the same key. It works by transmitting an audio frequency signal from the key to the immobiliser system in your car. If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will be deactivated and the engine will be able to 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 duplicate than mechanical keys. It is possible to duplicate a conventional key, but not a transponder key. Unlike the central locking element remote of a conventional key that relies on battery power, a transponder chip powered by an infrared (IR) signal that is transmitted by the antenna ring that is located on the ignition cylinder.

To activate the transponder chip the ignition cylinder has to be switched to ON. The ring emits a burst IR energy that is received by a microchip inside the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer checks the code in its memory with the one 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 in use it will shut down the engine and prevent the essential components from working.

The car immobiliser system is an an effective way to stop thieves, but it is also possible for it to be out of sync with the key or transponder chip. This can be due to interference or a system that is too sensitive. This could require the system to be reset. To do  Full Statement , simply disconnect the battery. After 15 minutes, you can reinstall the battery and restart the vehicle. This will reset the system and make it ready to accept your key again.

The security light is an immobiliser's way of alerting you to the presence of a problem. If you try to start the car and the light is solid on it indicates that the chip in your key doesn't match the code stored in the ECU.

The immobiliser will disconnect in the event that it is unable to recognize the code. It's hard to beat.

Modern cars have this system as standard. This makes it difficult to hot-wire a car or use a different key as a starter. The system works by checking the chip in a key fob or a key and sending a passcode back to the ECU (electronic control unit). The ECU is aware that it's the right key and hasn't been a compromise in the code. The system will not allow the car to start if it doesn't have the correct code, and some models will even notify the owner if a person tries to use a wrong fob or key.

The system is not foolproof, however. Some thieves have bypassed the immobiliser with techniques like 'hot-wiring.' This involves crossing the wrong wires within a vehicle's wiring to fool the ECU to believe that the proper key or fob is being used. This method is risky and requires extensive knowledge to avoid electrocuting oneself.  car remote key repair  are also employing more sophisticated methods such as Bluetooth or specialised apps to take over a car's data and remotely control it remotely.
