Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Nowadays, all vehicles are equipped with an engine immobilizer in order to prevent car theft. If your vehicle isn't starting after inserting the key fob there may be a problem with a transponder chip that is not transmitting an authorization code to the immobilizer system.
This is a quick fix that any auto locksmith on the Gold Coast can do. Let's take a look at the different parts of your car's immobiliser and what you can do to get it fixed.
Battery

Typically the key fob battery powers the remote opening and locking systems. The immobiliser isn't powered by the battery in the key fob. Instead, the immobiliser depends on the transponder chip that is located in the fob or key. This chip transmits a passcode from the fob or key to the immobilizer unit in the car, which could be integrated into the PCM (power control module), BCM (brake control module) instrument clusters, smart junction boxes, or standalone modules. The system checks the code to ensure it's correct. If it's not, the system will disable components crucial to starting the vehicle, such as the ignition or starter motor. The car will be nearly impossible to start if the driver doesn't have the correct key.
Since its inception, the immobiliser has been a very effective tool in reducing the theft of cars. Despite this it is not uncommon for thieves to look for new ways to bypass these security measures.

Transponder Chip
In cars manufactured after 1995, a tiny electronic chip called transponder is embedded in the head of your car key. Also known as a chip key or a 'transmitter and responder' key, it is designed to prevent the engine from starting if a third party has a copy of your car key. It works by sending radio signals from the key to your immobiliser system. If the code stored in the car's computer is in line with the signal sent by the key the immobiliser will be disarmed and the engine will start.
The key with the transponder is also referred to as a "fob" or a "smart" key, as it is more difficult to copy than a mechanical key. Using special techniques, it is feasible to copy a conventional car key, but not the transponder key. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder chip the ignition cylinder has to be turned on. The ring emits IR energy which is detected by a microchip in the key. The chip responds by transmitting a unique code to your car's immobiliser. The computer in the car compares the code stored in its memory with the transponder's and when the two codes match it will begin the engine.
The immobiliser will disable the engine if it detects an unauthorized key or transponder. It also stops all vital parts of the car from functioning. Without a functioning engine the car will not be able to move and it will be easy for criminals to wire the vehicle and then drive off.

If the system cannot identify a digital serial number from the chip inside your key it will disengage the engine immobiliser, preventing the car from getting started.
The car immobiliser is a fantastic read more way to deter thieves, but it can sometimes get out of in sync. This can be due to interference or the system is too sensitive. If this is the case it may need to be reset. To do this simply disconnect the battery. After 15 minutes, you can reinstall the battery and restart the car. This will reset the system and allow it to accept your key once more.
The security light is the car immobiliser's method of letting you know that there's an issue with the system. If you try to start the car but the light is solid on it means that the chip in more info your key doesn't match the code that is stored in the ECU. This can occur in the event that your car's key was replaced with a new one that is not programmed to work with the vehicle, or if the ECU has been swapped incorrectly.
If this is the situation, then it's time to go to a professional to have the key or the transponder chip properly programmed to your vehicle.

Modern cars come with this system as standard. This makes it extremely difficult to hot-wire a car or use a different key as a starter. The system works by analyzing the chip in the key fob or 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 code isn't compromised. The system won't allow the vehicle to start if it doesn't have the correct code, and some click here models will even notify the owner if someone tries to use an unapproved fob or key.
However, the system is not impervious to theft. Some thieves have managed to get around the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wire in a vehicle in order to fool the ECU. This is a risky method and requires a lot of expertise to avoid electrocuting yourself. Modern car thieves are also employing more sophisticated methods like Bluetooth or other specialized apps to steal a car's information and remotely control it remotely.
Car owners will frequently be greeted by warning lights that indicate an immobiliser that has gone out of control. This could be due to a variety of reasons but the most frequent one is a faulty battery in the keyfob. A simple replacement can fix this problem.
If this does not work, it could be that the transponder chip is faulty or the ECU is not compatible. This is more difficult to determine and fix since it could require an expert locksmith or a dealership. The car immobiliser could also be damaged if water manages to enter the system or is physically pulled away from its fob or key. If you encounter any of these problems it is a great idea to visit the local car dealer or garage for assistance.
