Key Fob Replacement and Reprogramming - Why Your Car Won't Start
The majority of vehicles have an immobilizer that prevents car theft. If your vehicle isn't starting after inserting the key fob, there could be a problem with a transponder chip that is not transmitting a security code to the immobiliser system.
This is a straightforward fix for any auto locksmith in Gold Coast. Let's take a look at the different parts of your vehicle's immobiliser and see what you can do.
Battery
If you're involved in the auto repair industry it is crucial to focus on your shop's revenue and cost-saving opportunities. You can accomplish this by offering key fob replacements as well as reprogramming your customers. This will not only help your customers but also boost the profits of your shop without subletting to the dealership.
The key fob battery powers the remote locking and opening systems. However, it doesn't provide power to the immobiliser. The immobiliser is powered by a transponder in the fob, key or instrument cluster. This chip transmits a passcode from the key or fob to the immobilizer unit of the car, which could 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 then validates the code to ensure that it is correct. If the code is incorrect it will disable the elements that are crucial to starting the car, like the ignition or starter motor. The car will be nearly impossible to start if the driver doesn't have the right key.
Since its introduction the immobiliser has proven to be an extremely effective tool for reducing car theft. Despite this the fact that thieves are always looking for new ways to get around these security measures. One of these methods includes a recent trend called the Kia Challenge on TikTok that showcased how easy it is to connect a vehicle with hot wires.
Most insurance companies now factor in the use of an immobiliser when they calculate premiums, which makes it more attractive to purchase an automobile that has this feature. However, even cars that came factory-fitted with an immobiliser may experience problems with it. These problems are often easy and cheap to fix. A dying or dead keyfob battery is typically the reason for a malfunctioning ignition immobiliser. A quick diagnostic test will identify the issue. If the issue continues to persist it could be due to other causes of the car's misbehaviour, including electrical issues or a wiring issue. It's best to let a professional diagnose the problem and solve it.
Transponder Chip
In cars manufactured after 1995, a small electronic chip, referred to as transponder is embedded in the head of your car key. Also known as a chip key or a 'transmitter and responder key, it's designed to stop the engine from starting if a third party has the same key. It works by sending the radio frequency signal from the key to the immobiliser system inside your car. If the code 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 start.
The key with the transponder is also referred to as a "fob" or a "smart" key due to the fact that it is more difficult to duplicate than mechanical keys. With the help of special techniques, it is feasible to duplicate a standard 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 needs to be turned to the ON position. The ring emits a flash of IR energy, which is detected by the microchip within the key. The chip responds by sending a unique code to the immobiliser in your car. The car's computer compared the code in its memory with that from the transponder chip and if they match, the engine will start.
The immobiliser shuts down the engine in the event of an unauthorised key or transponder. It also stops any vital components of the vehicle from working. The car will not move if the engine is not working. It is easy for a criminal to hot-wire it and drive off. This is a great security measure against crime, and is the reason why you should get your car key-immobiliser repaired promptly if it develops a fault. If you don't take this action and the security light auto key repair on your car will keep blinking, and you won't be able to start it.
Security Light
The immobiliser makes use of a tiny battery to send an electrical signal to the chip in your key. It is an anti-theft device that prevents anyone from opening your car without the right key. If the system is unable to detect an electronic serial number from the chip on your key, it will disable the engine immobiliser to prevent the car from starting.
This system for car immobilisation is an an effective way to stop thieves but sometimes it can be out of connection with the key or the transponder chip. This could be due interference or the system is too sensitive. If this is the situation, it could be necessary to reset. To do this, just disconnect the battery. After 15 minutes, reconnect the battery and then restart the car. This will reset the system and allow it to accept the key again.
The security light is an immobiliser's way of alerting you to an issue. If you try to start your car and the light stays on, it means that the chip in your key isn't compatible with the code stored in the ECU. This can occur when your car's key was replaced with an alternative key that is not compatible with the vehicle, or if an ECU has been swapped incorrectly.
If this is the case it is recommended to take your key or transponder chip to a professional for them properly programmed for your car. There is also the possibility that the system is not accepting the key because of an issue with the software or an update. To test this, place your key in the ignition and turn it to the ON position but don't attempt to start the engine. Keep the key in this position for ten minutes. The security light should come on, then go off. If it doesn't, you'll have to repeat the process and wait another 10 minutes. This should resolve the issue when you repeat the process three times.
Programming
The car immobiliser blocks the engine from running if a key or fob is not properly programmed. It utilizes a specific RFID chip that cannot be copied and has a digital serial number. The immobiliser will stop working when it is unable to recognize the code. It's tough to beat.
Modern cars have this system as standard. This makes it difficult to hot-wire a car or use a different key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU recognizes that it is the correct key and that there hasn't be compromised code. The system won't allow the car to start in the event that it does not receive the correct code. Some models even inform the owner when they attempt to use an incorrect fob or key.
However it isn't impervious to theft. Some thieves have bypassed the immobiliser by using techniques such as 'hot-wiring.' This involves crossing the wrong wires in the wiring of a vehicle to trick the ECU into thinking the appropriate fob or key is being used. This method is risky and requires extensive 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 a car's data and remotely control it via their mobile.
Car owners often notice warning lights that signal an immobiliser that has gone out of control. This could be due to a variety of reasons, but the most common is due to a damaged or dead battery in the key fob. The issue can be solved by a simple replacement.
If this does not work, it could be that the transponder chip may be defective or the ECU is mismatched. This is harder to determine and fix since it could require a specialist locksmith or dealership. A car's immobiliser can be damaged if water is able to enter the system or is physically pulled away from its fob or key. If you encounter any of these issues it is a great idea that you visit an auto dealer in your area or garage to seek help.
