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 won't start after inserting the key fob, it could be an issue with a transponder which isn't sending a security signal to the immobiliser.
This is a simple fix that any auto locksmith on the Gold Coast can do. Let's take a look at the different parts of your vehicle's immobiliser and discover what you can do.
Battery
If you're involved in the auto repair industry it is essential to focus on your shop's revenue and cost-saving opportunities. One way to do this is to offer key fob replacement and reprogramming to your customers. This will not only benefit your customers, but also increase your shop's profits, without having sublet the dealership.
The key fob battery powers the remote car key repair locking and opening systems. However, it doesn't provide power to the immobiliser. Instead, the immobiliser relies on the transponder chip located in the key fob repair or fob. This chip transmits a passcode from the fob or key to the immobilizer unit in the car, which can be integrated into the PCM (power control module), BCM (brake control module) instrument cluster, smart junction boxes, or standalone modules. The system then checks the code to ensure that it is correct. If the code is not correct, the system disables components that are essential to the start of the car, such as the starter motor or ignition. The car will be nearly impossible to start if you do not have the right key.
Since its inception the immobiliser has proved to be an extremely effective tool for reducing the theft of cars. Yet thieves are always trying to get around these security measures. One of these is the Kia Challenge trend on TikTok that demonstrates how easy it is to connect hot wires to an vehicle.
Insurance companies are now factoring the use of an immobiliser in calculating premiums. This makes it more appealing to purchase a vehicle with this feature. However, even vehicles that were factory-fitted with an immobiliser could face problems with it. Fortunately, these problems are usually easy and cheap to fix. Most times an immobiliser that is not working properly is caused by a dead or dying key fob battery. A quick diagnostic test will identify the issue. If the issue persists, it could be due to electrical problems or wiring issues. It's best to seek out a professional to determine the issue and solve it.
Transponder Chip
A tiny electronic chip, referred to as transponder, is incorporated inside the head portion of your car keys. The 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 prevent your engine from starting when you have the same key. It functions by sending a radio frequency signal from the key to the immobiliser system in your car. If the code in the car's computer matches that signal sent from the key, it will deactivate the immobiliser and allow the engine to start.
The key with the transponder chip is often referred to as a 'fob' or a "smart" key because it is much more difficult to copy than a conventional mechanical key. 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 activate the transponder, the ignition cylinder needs to be in the ON position. The ring emits a blast of IR energy that is absorbed by the microchip in the key. The chip then sends a unique code to the immobiliser inside your car. 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 begin to rev.
If the immobiliser detects an unauthorized transponder or key is in use it will shut down the engine and stop any of its essential components from functioning. The car will not move when the engine isn't functioning. It's easy for a criminal hot-wire it and drive off. This is a powerful way to deter criminals and is one of the main reasons why it's important to have your car key immobiliser repaired as soon as you notice an issue. If you don't, the security light on your car will keep flashing and it will be inaccessible for you to start your engine.
Security Light
The immobiliser is powered by a tiny battery that transmits an electrical signal to the transponder chip within your key. This is an anti-theft device that blocks anyone from driving your vehicle without the right key. If the system is unable to detect a digital serial from the chip on your key, it will disable the engine immobiliser to stop the car from starting.
This system for car immobilisation is an effective in stopping thieves, but it is also possible for it to get out of in sync with the key or transponder chip. This could be due to interference or an immobiliser that is too sensitive. If this is the situation, 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 key system to ensure that it is ready to accept your keys again.
The security light is the vehicle immobiliser's way of telling you that there is an issue with the system. If the light is illuminated and you try to start your Car Key Immobiliser Repair, it is a sign that the code that is stored in the ECU does not match the chip in 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 situation it is recommended to bring your transponder key or chip to a professional for them correctly programmed for the vehicle you are driving. There is also the possibility that the system is not accepting the key due to an update or software issue. To test, insert your key into the ignition and turn it to the ON position. Do not try to start the car. Let the key remain in this position for ten minutes. The security light should turn on, and then go off. If it doesn't work, you'll have to repeat the process and wait another 10 minutes. Do this three times, and the issue should be solved.
Programming
The car immobiliser stops the engine from running when a key or fob is not properly programmed. It uses a special RFID microchip that cannot be copied and has its own digital serial number. The immobiliser will be disengaged when it is unable to recognize the code. That's why it's difficult to defeat.
Modern cars have this system as standard. This makes it extremely difficult to wire the car hot or use another key for starter. The system works by analyzing the chip inside the key fob or key, and transmitting a passcode to the ECU (electronic control unit). The ECU will then verify that it's the right key and that the passcode hasn't been compromised. The system won't allow the car to start when it doesn't receive the correct code. Some models even notify the owner if they attempt to use an incorrect fob or key.
However it isn't completely secure. Some thieves have managed to bypass the immobiliser using methods like 'hot-wiring.' This involves crossing the wrong wire in an automobile to trick the ECU. This is a risky technique and requires a lot of expertise to avoid electrocuting yourself. Additionally, many modern car thieves have moved over to more advanced methods such as using specialised apps or Bluetooth to take over the car's data and then remotely control it using their mobile car key repair.
Car owners often see warning lights that indicate that the immobiliser has gone haywire. It can happen for a variety of reasons however the most common reason is a defective battery in the keyfob. The issue can be solved by a simple replacement.
If this does not work it could be because the transponder chip may be defective or the ECU is not compatible. This is more complicated to determine and fix and may require a specialist car locksmith or dealership. However, a car's immobiliser may be damaged by water intrusion or even being removed from the fob or key. If any of these issues occur it's recommended to visit the nearest garage or dealer for assistance.
