Key Fob Replacement and Reprogramming - Why Your Car Won't Start
The majority of vehicles have an immobilizer to prevent theft. If your vehicle doesn't start after inserting the key fob it could be due to a problem with a transponder that's not sending a security signal to the immobiliser.
This is a simple 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
It is important that you concentrate on the revenue and cost-savings opportunities of your auto repair shop. 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 profits without subletting to the dealership.
Typically, the key fob battery powers the remote locking and opening systems. However, it does not supply power to the immobiliser. The immobiliser is powered by a transponder located 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 cluster, smart junction boxes, or standalone modules. The system examines the code to make sure it is correct. If the code is incorrect the system will disable elements that are crucial to starting the car, such as the starter motor or ignition. This makes the car difficult to start without the right key.
Since its inception, the immobiliser has been an extremely effective tool for reducing car theft. However the thieves are always trying to get around these security measures. One of these strategies is the Kia Challenge trend on TikTok that shows how simple it can be to hot-wire an automobile.
Most insurance companies now factor in the use of an immobiliser when calculating rates, which makes it more attractive to shop for cars that already have this feature. Even vehicles that are factory fitted with an immobiliser might have issues. These problems are often easy and affordable to fix. A dead or dying keyfob battery is typically the reason for a malfunctioning ignition immobiliser. A quick diagnostic test can reveal this issue. If the problem persists then it could be due to electrical issues or wiring issues. It is best to seek out a professional to identify the issue and then solve it.
Transponder Chip
A small electronic chip, called transponder, is embedded in the head of your car keys. This technology was first introduced in vehicles manufactured after 1995. It is also known as a "chip key" or a "transmitter-responder" key. Its function is to prevent the engine from starting when you have an identical 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 more difficult to duplicate than a traditional mechanical key. It is possible to duplicate a conventional key but not a transponder key. Transponder chips are powered by an infrared signal and not battery power.
To activate the transponder chip, the ignition cylinder needs to be turned to the ON position. The ring car keying repair emits a burst IR energy that is picked up by a microchip in the key. The chip then sends an individual code to the immobiliser in your car. The car's computer compared the code stored in its memory to the one from the transponder chip and if they match, the engine will start.
The immobiliser will disable the engine when it detects an unauthorized key or transponder. It also stops any essential parts of the car from functioning. The car will not move in the event that the engine is not functioning. It would be easy for a criminal hot-wire it to drive away. This is a powerful deterrent against crime and it is one of the reasons why it is essential to get your car key immobiliser repaired when you spot an issue. If you don't take this action and the security light on your car will continue flashing and you will not be able to begin it.
Security Light
The immobiliser utilizes a small battery to transmit an electrical signal to the chip inside your key. This device is designed to prevent anyone from starting the car if they don't have the correct keys. If the system cannot detect a digital serial number from the chip on your key, it will shut off the engine immobiliser to prevent the car starting.
This car immobiliser system is effective in stopping thieves but sometimes it can become out of connection with the key or the transponder chip. This can be due to interference or the system being too sensitive. This may need the system to be reset. To do this simply disconnect the battery. Leave it disconnected for about 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 once again.
The security light is an immobiliser's method of alerting you to an issue. If you try to start the car but the light stays on it indicates that the chip in your key doesn't match the code that is stored in the ECU. This can occur when your car's key was replaced with an alternative key that is not programmed for the vehicle, or if the ECU has been swapped incorrectly.
If this is the case you should take your transponder or key chip to a professional for them correctly programmed for the vehicle you are driving. It is possible that the system isn't able to accept the key due to a software update or glitch. To test, put your key into the ignition and then turn it to the ON position. Do not try to start the vehicle. The key should remain in this position for ten minutes. The security light should turn on, then go off. If it does not, you will need to repeat this process and wait for another 10 minutes. Repeat the process three times and the issue should be solved.
Programming
The car immobiliser stops the engine from running when the fob or key is not programmed correctly. It is based on a specific RFID microchip that isn't able to be duplicated and comes with its own serial number. The immobiliser will disengage when it is unable to recognize the code. That's why it's difficult to defeat.
Modern cars come with this system as standard. This makes it extremely difficult to connect the car to a hot wire or use another key for starter. The system works by sending a code from the key fob to the ECU. The ECU is aware that it's the right key and that it doesn't have to been a compromise in the code. The system won't allow the car to start if it does not receive the correct code. Certain models will even notify the owner if they attempt to use an unapproved 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 wire in a vehicle in order to cause a malfunction in the ECU. This is a risky method and requires extensive experience to avoid electrocuting oneself. Modern car thieves are employing more sophisticated methods, for instance, Bluetooth or specialised apps to take over a car's data and remotely control it.
Car owners often notice warning lights that signal an immobiliser that has gone out of control. This can happen for various reasons, but the most frequent causes is a faulty or dead battery in the key fob. This issue can be resolved by an easy replacement.
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 diagnose and fix and may require a specialist car locksmith or dealership. However, a car immobiliser can also be damaged by water intrusion, or even being removed from the fob or key. If you experience any of these problems it is a good idea to visit an auto dealer in your area or garage for assistance.
