Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Most cars are equipped with an immobilizer system that stops car theft. If your vehicle won't start after inserting the key fob there could be an issue with a transponder chip that is not transmitting an encryption code to the immobiliser system.
This is a simple fix that any auto locksmith on the Gold Coast can do. Let's look at the various elements of your car's immobiliser and what you can do to get it fixed.
Battery
If you're involved in the auto repair industry it is crucial to focus on your shop's earnings and cost-saving opportunities.

The key fob battery powers the remote locking and opening systems. However, it does not power the immobiliser. The immobiliser is powered by the transponder in the fob, key or instrument cluster. The chip transmits a code 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 will check the code to make sure it is correct. If the code is incorrect it will disable the components that are crucial to start the car, such as the ignition motor or starter motor. This will make the car difficult to start without the correct key.
Since its inception the immobiliser has proved to be an extremely effective tool for reducing the theft of cars. However it is not uncommon for thieves to look for new ways to circumvent these security measures. One of these methods is the Kia Challenge trend on TikTok that shows how simple it is to connect hot wires to an automobile.
Insurance companies are now incorporating in the use an immobiliser in calculating premiums. This makes it more attractive to purchase a vehicle with this feature. Even cars equipped with an immobiliser might have issues. Fortunately, these issues are usually easy and cheap to fix. A dead or dying keyfob battery can be the cause of a malfunctioning ignition immobiliser. This can be identified with an easy diagnostic test. If the issue persists, it could be due to electrical problems or wiring issues. If this is the case, it's best to have a professional diagnose and repair the problem.
Transponder Chip
In vehicles manufactured after 1995, a tiny electronic chip referred to transponder is embedded in the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its purpose is to stop your engine from starting when you have the same key. It works by transmitting a radio frequency from the key to your immobiliser system. If the code stored in the car's computer matches the signal sent by the key, the immobiliser will be deactivated and the engine will begin to run.
The key that is equipped with a transponder chip can be referred to as a 'fob' or a 'smart' key because it is much more difficult to copy than a traditional mechanical key. Utilizing special methods, it is possible to copy a standard car key but not transponder keys. Unlike the central locking element remote of a standard key which uses battery power, a transponder chip is powered by the infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To activate the transponder the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy that is received by a microchip within the key. The chip responds by transmitting a unique code to your car's immobiliser. The car's computer compared the code stored in its memory with the one from the transponder chip, and if they match, the engine will start.
If the immobiliser detects that an unauthorized transponder or key is in use, it will disable the engine and stop any of its essential components from functioning. The car won't move in the event that the engine is not working. It would be easy for criminals to wire it to drive away. This is a powerful deterrent to crime and it is one of the reasons why it is essential to get your car key immobiliser repaired immediately you discover a fault with it. If you don't, the security light in your car will keep flashing and it will be inaccessible for you to start your engine.
Security Light
The immobiliser makes use of a tiny battery to send an electrical signal to the chip that is in your key. This device is designed to prevent anyone from starting their car without the proper keys. If the system can't detect a serial number digital from the chip inside your key, it will disable the engine immobiliser and prevent the car from getting started.
The car immobiliser system is an effective in stopping thieves, but it is also possible for it to become out of connection with the key or transponder chip. This could be due to interference or the system being too sensitive. If this is the case it might need to be reset. To do this, disconnect the battery. After 15 minutes, reconnect the battery and restart the car. This will reset the key system so that it is ready to accept your keys once again.
The security light is a way of alerting you to an issue. If the light is on and you try to start your car, it means that the code that is stored in the ECU does not match the chip on the key. This could happen if you have recently replaced your car's key with a different one that isn't programmed to the vehicle, or if you've had a bad swapped ECU.
If this is the case you should take your key or transponder chip to a professional to get them properly programmed for your vehicle. It's possible that the system will not accept the key because of a software update or bug. To test this, put your key in the ignition and switch it to the ON position but don't try to start the engine. Keep the key in this position for ten minutes. The security light should turn on, then turn off. If it doesn't work, you'll have to repeat the process and wait for another 10 minutes. This should resolve the issue if you repeat it three times.
Programming
A car immobiliser stops a car's engine from running without a key that is programmed correctly or fob. It uses a special RFID chip that cannot be copied and is equipped with a digital serial number. The immobiliser will be disconnected when it doesn't recognize the code. It's difficult to beat.
Modern cars are fitted with this security system by default. This makes it very difficult to connect the car to a hot wire or use another key for starter. The system works by analyzing the chip in a 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 right key and that the passcode isn't compromised. The system won't allow the car to begin when it doesn't receive the correct code. Some models even inform the owner if they attempt to use a wrong fob or key.
The system isn't 100% secure, however. Certain thieves have been able to bypass the immobiliser using techniques like 'hot-wiring'. This involves using the wrong wiring in an automobile to cause a malfunction in the ECU. This is a risky technique and requires a lot of expertise to avoid electrocuting yourself. In addition, many modern car thieves have shifted to more sophisticated methods such as using specialised apps or Bluetooth to steal the car's data and then remotely control it via their phones.
Car owners often see warning lights that signal that the immobiliser has gone off the rails. This could be due to a variety of reasons, but one of the most frequent causes is a dead or defective battery on the key fob. This problem can be fixed by a simple replacement.
If this isn't working the transponder chip could be defective or not compatible with the ECU. This is more difficult to fix and diagnose as it may require a professional locksmith or dealership. However, a car immobiliser can also be damaged due to water intrusion, or even being pulled away from the fob or key. If you encounter any of these issues, it is a good idea that you visit an auto dealer in your area or garage for assistance.
