Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Currently, most vehicles come equipped with an engine immobilizer in order to protect against theft of cars. If your vehicle will not start after inserting the key fob it could be due to an issue with a transponder that's not sending a security message to the immobilizer.
This is a simple fix for any auto locksmith in Gold Coast. Let's take a look at the different components of your car immobiliser and what you can do to fix it.
Battery
If you are involved in the auto repair industry it is crucial to concentrate on your shop's revenue and cost-saving opportunities. You can achieve this by offering key fob replacements as well as reprogramming your customers. This will not only benefit your customers, but will also boost your shop's profit without having to sublet to the dealership.
The key fob battery powers the remote locking and opening systems. However, it does not supply power to the immobiliser. Instead, the immobiliser is dependent on the transponder chip that is located in the fob or key. This chip sends a passcode to the car's immobilizer device, which may be built into the PCM, BCM or instrument cluster, smart junction box or standalone module. The system checks the code to ensure it is correct. If it is not it is, the system will shut down parts that are essential to start the vehicle, like the starter motor or ignition. The car will be nearly impossible to start if you don't have the correct key.
The immobiliser system has been extremely effective in reducing car theft since its first introduction. Despite this the fact that thieves are always looking for new ways to circumvent these security measures. One of these methods includes a recent trend known as the Kia Challenge on TikTok that showcased how easy it is to connect a vehicle with hot wires.
The majority of insurance companies now factor in the use of an immobiliser when they calculate premiums, which makes it even more appealing to purchase an automobile that has this feature. However, even cars equipped by the manufacturer with an immobiliser could face issues with it. These issues are usually simple and inexpensive to solve. Most of the time an immobiliser that is not working properly is caused by an inactive or dead key fob battery. 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 behavior, such as electrical issues or a wiring issue. If this is the case, it's best to have a professional diagnose and repair the issue.
Transponder Chip
A small electronic chip, also known as a transponder, is built in the head of your car keys. The technology was introduced in vehicles manufactured after 1995. It is also referred to as a "chip key" or a "transmitter-responder" key. Its function is to prevent the engine from starting when you have a duplicate of your key. It works by sending an audio signal from the key to the immobiliser system. If the code stored 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 that has a transponder is also referred to as a "fob" or a "smart" key, because it is more difficult to copy than mechanical keys. Utilizing special methods, it is possible to copy a conventional car key however, not transponder keys. Contrary to the remote central locking element of a conventional key that relies on battery power, a transponder chip is powered by an infrared (IR) signal transmitted by the antenna ring that is located on the ignition cylinder.
To turn on the transponder, the ignition cylinder needs to be in the ON position. The ring emits a burst of IR energy, which is absorbed by the microchip in the key. The chip responds with an individual code to the immobiliser in your car. The car's computer checks 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 shut down the engine when it detects an unauthorised key or transponder. It also stops any vital parts of the car from functioning. The car won't move if the engine is not working. It would be easy for criminals to wire it to drive away. This is a great security measure against crime, and is why you should have your car's key-immobiliser fixed as soon as you can in the event of a malfunction. If you don't do this, the security light in your car will keep flashing and it will be impossible for you to start your engine.
Security Light
The immobiliser utilizes a small battery to send an electrical signal to the chip inside your key. This is an anti theft device that stops anyone from opening your car without the proper key. If the system cannot identify a digital serial number from the chip in your key, it will disable the engine immobiliser and prevent the car from beginning.
This system for car immobilisation is an an effective way to stop thieves, however it can get out of sync with the key or the transponder chip. This can be caused by interference or the system being too sensitive. This could require the system to be reset. To do this simply disconnect the battery. It should be left disconnected 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 car immobiliser's method of letting you know that there is an issue with the system. If you try to start the car but the light stays on it indicates that the chip in your key isn't in sync with the code stored in the ECU. This can happen in the event that your car's key was replaced with a new key that's not compatible with the vehicle, or when an ECU was swapped in a wrong manner.
If this is the situation you should take your key or transponder chip to a professional to have them correctly programmed for the vehicle you are driving. It's possible that your system won't accept the key because of a software update or bug. To test, put your key in the ignition and turn the ON position. Do not attempt to start the vehicle. Keep the key in this position for ten minutes. This will cause the security light to light up and then to go off. If it doesn't work, you'll need to repeat the process and wait for another 10 minutes. Repeat the process three times and the problem is likely to be solved.
Programming
The car immobiliser stops the engine from running if a key or fob is not programmed correctly. It makes use of a unique RFID microchip that isn't able to be duplicated and comes with its own serial number. The immobiliser will stop working if it doesn't recognise the code. It's hard to beat.
Modern cars come with this system as standard. This repair car key makes it extremely difficult to hot-wire the car or use a different key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU is then able to determine that it's the correct key and that the passcode hasn't been compromised. The system won't permit the vehicle to start if it does not receive the correct code. Some models will even report back to the owner if a person tries to use a wrong fob or key.
However, the system is not impervious to theft. Some thieves have managed to bypass the immobiliser using methods like 'hot-wiring.' This involves crossing the wrong wiring in an automobile to fool the ECU. This is a risky method and requires a lot of expertise to avoid electrocuting yourself. Plus, a lot of modern car thieves have switched over to more advanced methods like using specialized apps or Bluetooth to steal the car's information and remotely control it via their phone.
Owners of cars will often see warning lights that indicate an immobiliser malfunctioning. It can happen for a variety of reasons, but the most common one is a faulty battery in the keyfob. The issue can be solved by replacing the battery.
If this doesn't work it could be because the transponder chip is faulty or the ECU is not matched. It is more difficult to determine and fix because it requires a specialist car locksmith or dealership. The car immobiliser could also be damaged if water is able to get into the system, or if it is physically removed from its fob or key. If any of these issues occur it's a good idea visit an auto garage or a local dealer for assistance.
