Key Fob Replacement and Reprogramming - Why Your Car Won't Start
The majority of vehicles have an immobilizer system that stops car theft. If your vehicle won't start after inserting the key fob there may be a problem with a transponder chip that is not sending a security code to the immobiliser system.
This is a straightforward fix that any auto locksmith on the Gold Coast can do. Let's look at the various components of your vehicle's immobiliser and see what you can do.

If you're working in the field of auto repair, it is important to be aware of your shop's earnings and cost-saving opportunities.

This will not only assist your customers but also boost the profits of your business without having to sublet to the dealership.
Typically the battery for the key fob powers the remote locking and opening systems. The immobiliser isn't powered by the battery in the key fob. The immobiliser is powered through the transponder located in the key, fob or instrument cluster. The chip transmits a passcode from the fob or key 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 clusters, smart junction boxes, or standalone modules. The system then verifies the code to ensure it is correct. If it's not, the system will disable components crucial to starting the vehicle, such as the ignition or starter motor. This will make the car difficult to start without the right key.
The immobiliser system has proven highly effective in decreasing car theft since it was first introduced. However, thieves are constantly trying to get around these security measures. One of these strategies is the Kia Challenge trend on TikTok that demonstrates how easy it is to wire an vehicle.
Most insurance companies now factor in the use of an immobiliser in calculating rates, which makes it more attractive to purchase cars that already have this feature. However, even cars that came factory-fitted with an immobiliser may experience issues with it.

A quick diagnostic test can uncover the problem. If the issue continues, it could be due to electrical problems or wiring issues.

Transponder Chip
A tiny electronic chip, called transponder, is incorporated into the head portion of your car keys. This technology was introduced in cars manufactured after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting when another person has an identical key. It functions by sending a radio frequency signal from the key to the immobiliser system of your car. If the code in the car's computer matches the signal sent from the key, it will disarm the immobiliser and allow the engine to start.
The key with a transponder can also be referred to as a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than mechanical keys. It is possible to duplicate a standard key, but not a transponder one. Transponder chips are powered by an infrared signal, not battery power.
To turn on the transponder, the ignition cylinder has to be in the ON position. The ring emits a burst of IR energy that is detected by the microchip inside the key. The chip then responds with a unique code to the immobiliser inside your car. The car's computer compares the code stored in its memory with that from the transponder chip and If they are compatible the engine will be able to start.
If the immobiliser detects that an unauthorised transponder, key or other device is being used it will shut down the engine and prevent the essential components from functioning. Without a functioning engine the vehicle won't be able to move and it could be easy for a criminal to hot-wire the vehicle and then drive off. This is a great 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 continue to flash and it will be difficult for you to start your engine.
Security Light
The immobiliser is powered by a tiny battery that sends an electrical signal to the transponder chip in your key. This device is designed to prevent anyone from starting the car if they don't have the proper keys. If the system is unable to detect a digital serial number from the chip in your key, it will shut off the engine immobiliser to prevent the car starting.
The car immobiliser system is an effective in stopping thieves but sometimes it can become out of sync with the key or transponder chip. This could be due to interference or the system being too sensitive. If this is the case it may need to be reset. To do this, just disconnect the battery. Then leave it off for around 15 minutes before reinstalling it and start the vehicle. This will reset the system and allow it to accept your key once more.
The security light is the vehicle immobiliser's method of letting you know that there's a problem with the system. If the light is on when you attempt to start your car, it means that the code that is stored in the ECU does not match the chip inside the key. This can happen if you have recently replaced your car's key with another that isn't programmed to the vehicle, or in the event that you've had a defective swapped ECU.
If this is the case, then it's time to talk to a professional and have the the transponder chip properly programmed to your vehicle. It's possible that your system will not accept the key due to a software update or glitch. To test this, insert your key in the ignition and turn it to the ON position. Don't try to start the vehicle. Keep the key in this position for 10 minutes. This will cause the security light to turn on and to turn off. If it doesn't, you'll need to repeat the process and wait for another 10 minutes. Repeat this three times, and the issue should be solved.
Programming

It utilizes a specific RFID chip that is unable to be duplicated and has a unique digital serial number. The immobiliser will stop working when it is unable to recognize the code. read this article to beat.
Modern cars have this system as standard. This makes it extremely difficult to wire the car hot or use a different key as a starter. The system works by sending a code from the key fob to the ECU. The ECU then knows that it's the right key and that the code isn't compromised. The system will not allow the vehicle to start if it does not receive the correct code, and some models will even report back to the owner if a person tries to use an incorrect key or fob.
The system isn't foolproof, however. Some thieves have bypassed the immobiliser with techniques like 'hot-wiring.' This involves crossing the wrong wires through the wiring of a vehicle to trick the ECU into thinking the appropriate fob or key is being used. This is a risky method and requires extensive knowledge to avoid electrocuting oneself. Modern car thieves are using more advanced methods, like Bluetooth or specialised apps to obtain information about a vehicle and remotely manage it.
Car owners will often get warning lights that indicate the immobiliser has gone haywire. This can happen for various reasons, but the most common is due to a damaged or dead battery in the key fob. A simple repair should resolve this problem.
If this doesn't work the transponder chip could be defective or mismatched with the ECU. This is more difficult to determine and fix since it may require an expert locksmith or a dealership.

If you experience any of these problems it is a good idea to visit the local car dealer or garage to seek help.
