Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Nowadays, all vehicles are equipped with an engine immobilizer to protect against theft of cars. If your vehicle will not start after inserting the key fob, it could be an issue with a transponder which isn't sending a security message to the immobilizer.
This is a straightforward 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 get it fixed.
Battery
It is crucial to focus on the cost-savings and revenue opportunities of your auto repair shop. You can achieve this by providing key fob replacements as well as reprogramming your customers. This will not only help your customers, but it will also add to the profits of your shop without subletting to the dealership.
Typically the key fob battery powers the remote opening and locking systems. The immobiliser is not powered by the battery in the key fob. Instead, the immobiliser relies on the transponder chip on the fob or key. This chip sends a passcode to the car's immobilizer unit that can be integrated into the PCM, BCM, instrument cluster, smart junction box or standalone module. The system examines the code to ensure it's correct. If it is not, the system will disable elements that are crucial to the start of the vehicle, like the starter motor or ignition. The car will be impossible to start if you don't have the right key.
Since its inception the immobiliser has proved to be a very effective tool in reducing the theft of cars. Even so thieves are always looking for ways to circumvent these security measures. One of these methods includes an upcoming trend called the Kia Challenge on TikTok that showcased how easy it is to hot-wire a vehicle.
Most insurance companies now factor in the use of an immobiliser when they calculate premiums, making it even more appealing to shop for a car that already has this feature. Even cars that are factory-fitted with an immobiliser could have issues. Fortunately, these problems are usually easy and cheap to fix. The majority times an immobiliser that is not working properly is the result of the dying or dead key fob battery. 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 consult a professional for a diagnosis and repair the problem.
Transponder Chip
A tiny electronic chip, also known as transponder, is incorporated in the head of your car keys. This technology was introduced in cars manufactured after 1995. It is also known as a "chip key" or a "transmitter-responder" key. Its goal is to stop your engine from starting if someone else has an identical key. It works by transmitting radio signals from the key to your immobiliser system. If the code stored in the car's computer matches the signal from the key, it will disable the immobiliser and allow the engine to begin.
The key that has a transponder is also called a "fob" or a "smart" key due to the fact that it is more difficult to copy than mechanical keys. It is possible to duplicate a conventional key, but not a transponder one. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder, the ignition cylinder needs to be in the ON position. The ring emits a flash of IR energy, which is absorbed by the microchip within the key. The chip then sends a unique code to the immobiliser of your car. The car's computer compares the code in its memory to the one from the transponder chip and If they are compatible the engine will be able to start.
The immobiliser will disable the engine if it detects an unauthorized key or transponder. It also stops all vital components of the car from functioning. Without a functioning engine the car will not be able to move and it could be easy for criminals to connect the vehicle to a hot wire and drive away. This is a great security measure against crime, and is why you should have your car's key-immobiliser repaired promptly in the event of a malfunction. If you don't fix it, the security light in your car will continue to flash and it will be impossible to start your engine.
Security Light
The immobiliser is powered by a tiny battery that transmits an electrical signal to the transponder chip in your key. This is an anti-theft device that blocks anyone from driving your car without the right key. If the system is not able to recognize a digital serial number from the chip in your key, it will disable the engine immobiliser, which will stop the car from starting.
The car immobiliser system is an an effective way to stop thieves but sometimes it can get out of sync with the key or the transponder chip. This could be due interference or a system that is too sensitive. This could need a reset. To do this, just disconnect the battery. It should be left disconnected for around 15 minutes then reinsert it and begin the car. This will reset the key system, so that it is ready to accept your keys again.
The security light is the car 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 is a sign that the code in the ECU is not compatible with the chip on the key. This can occur when your car's key has been replaced with an alternative key that is not programmed for the vehicle, or if the ECU was swapped in a wrong manner.
If this is the case, then it's time to talk to a professional to have the the transponder chip properly programmed to your vehicle. There is also the possibility that the system isn't accepting the key due to an issue with the software or an update. To test, insert your key into the ignition and turn it to the ON position. Do not attempt to start the vehicle. Keep the key in this position for 10 minutes. This will cause the security light to come on and then to turn off. If it doesn't, you'll need to repeat the procedure and wait another 10 minutes. Repeat this three times and the issue will be resolved.
Programming
A car immobiliser stops the engine of a car from running without a correctly programmed key or fob. It uses a special RFID chip that can't be duplicated and has a unique digital serial number. The immobiliser will stop working if it does not recognise the code. It's difficult to beat.
Modern cars are equipped with this security system in the standard configuration. This makes it extremely difficult to hot-wire a car or utilize a different key for starter. The system works by checking the chip inside a key fob or a key and sending a passcode back 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 in the event that it does not receive the correct code. Certain models will even notify the owner when they attempt to use an incorrect fob or key.
The system is not foolproof, however. Some thieves have managed to bypass the immobiliser with techniques such as 'hot-wiring.' This involves crossing the wrong wires through the wiring of a vehicle, which fools the ECU into thinking that the appropriate fob or key is being used. However, this is extremely risky and requires a lot of experience in order to do it without electrocuting yourself. Plus, a lot of modern car thieves have shifted over to more advanced methods such as using specialised apps or Bluetooth to take over a car's data and remotely control it from their phones.
Car owners often see warning lights that indicate an immobiliser malfunctioning. This can occur for various reasons but the most frequent one is a malfunctioning battery in the keyfob. A simple repair should key repair resolve the issue.
If this isn't working the transponder chip could be defective or not compatible with the ECU. This is harder to fix and diagnose as it could require a specialist locksmith or dealership. A car's immobiliser can be damaged if water is able to get into the system or is physically removed from its fob or key. If you experience any of these issues, it is a good idea that you visit the local car dealer or garage for assistance.
