Key Fob Replacement and Reprogramming - Why Your Car Won't Start
Most vehicles are equipped with an immobilizer that prevents car theft. If your vehicle won't start after inserting the key fob, there may be a problem with the transponder chip not transmitting an encryption code to the immobiliser system.
This is a quick fix for any auto locksmith in Gold Coast. Let's look at the various components of your vehicle's immobiliser to discover what you can do.
Battery
If you are involved in the auto repair industry it is essential to concentrate on your shop's revenue and cost-saving opportunities. One method to achieve this is to offer key fob replacement and reprogramming services to your customers. This will not only assist your customers but also add to the profits of your shop without subletting to the dealership.
Typically the key fob battery powers the remote locking and opening systems. The immobiliser is not powered by the battery in the key fob. Instead, the immobiliser depends on the transponder chip in the fob or key. This chip transmits a code to the car's immobilizer unit that can be integrated into the PCM, BCM or instrument cluster smart junction box, or standalone module. The system then validates the code to ensure that it is correct. If the code is not correct it will disable the elements that are crucial to the start of the car, such as the starter motor or ignition. The car will be impossible to start if you don't have the correct key.
Since its inception, the immobiliser has been a very effective tool in decreasing car theft. Despite this it is not uncommon for thieves to look for new ways to bypass these security measures. One of these methods includes a recent trend known as the Kia Challenge on TikTok that showed how easy it was to connect a vehicle with hot wires.
Insurance companies are now incorporating the use of an immobiliser in calculating premiums. This makes it more attractive to buy a car with this feature. However, even cars equipped by the manufacturer with an immobiliser could face issues with it. These problems are often easy and affordable to fix. Most times an immobiliser that is not working properly is the result of the dying or dead key fob battery. A quick diagnostic test will reveal this issue. If the problem persists then it could be due to electrical issues or wiring issues. If this is the case, it's recommended to have a professional diagnose and fix the problem.
Transponder Chip
A tiny electronic chip, also known as transponder, is embedded into the head portion of your car keys. The technology was introduced in vehicles manufactured after 1995. It is also referred to a "chip key" or a "transmitter-responder" key. Its purpose is to prevent your engine from starting if you have the same key. It functions by sending the radio frequency signal from the key to the immobiliser system inside your car. If the code on the car's computer is in line with the signal transmitted by the key, it will disarm the immobiliser and allow the engine to start.
The key with the transponder chip can be referred to as a 'fob' or a 'smart' key because it is much more difficult to duplicate than a conventional mechanical key. It is possible to duplicate a traditional key, but not a transponder key. Transponder chips are powered by an infrared signal, not battery power.
To activate the transponder chip the ignition cylinder needs to be switched to ON. The ring emits a blast of IR energy that is picked up by the microchip in the key. The chip then responds with an individual code to the immobiliser in your car. The car's computer checks the code stored in its memory with the one from the transponder chip and when they match the engine will be able to start.
If the immobiliser detects that an unauthorised transponder, key or other device is being used it will shut down the engine and stop any of its vital components from working. The car will not move if the engine is not working. It's easy for a criminal to hot-wire it and drive off. This is a great security measure against crime, and is why you should have your car key-immobiliser repaired as quickly as possible in the event of a malfunction. If you don't do this, the security light on your vehicle will continue blinking, and you won't be able to start it.
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 prevents anyone from opening your vehicle without the proper key. If the system is unable to detect a digital serial number from the chip on your key, it will disable the engine immobiliser to stop the car starting.
This car immobiliser system is an effective way to stop thieves, however it can get out of connection with the key or the transponder chip. This can be due to interference or an immobiliser that is too sensitive. This could require an adjustment. To do this, simply disconnect the battery. Then leave it off for around 15 minutes, then insert it and begin the car. This will reset the system and make it ready to accept your key again.
The security light is an immobiliser's method of alerting you to an issue. If you attempt to start the car but the light stays on, it means that the chip inside your key isn't in sync with the code that is stored in the ECU. This can happen in the event that your car's key was replaced with a new one that is not programmed to work with the vehicle, or if an ECU was not swapped correctly.
If this is the case then you need to go to a professional to have the key or the transponder chip properly programmed to your vehicle. It is possible that the system won't accept the key because of a software update or bug. To test this, put your key in the ignition and turn it to ON but don't try to start the engine. Let the key stay in this position for 10 minutes. The security light should come on, then turn off. If it doesn't, you'll have to repeat the procedure and wait another 10 minutes. This should solve the issue if you repeat it three times.
Programming
The car immobiliser prevents the engine from running when the fob or key are not programmed correctly. It makes use of a unique RFID microchip that isn't able to be duplicated and comes with its own digital serial number. The immobiliser will disconnect in the event that it is unable to recognize the code. It's tough to beat.
Modern cars come with this system as standard. This makes it difficult to hot-wire a car or utilize a different key for starter. The system works by sending a passcode from the key fob to the ECU. The ECU will then verify that it's the right key and that the passcode isn't compromised. The system won't allow the car to start in the event that it does not receive the correct code. Some models even notify the owner when they attempt to use a wrong fob or key.
However, the system is not impervious to theft. Some thieves car key remote repairs have gotten around the immobiliser using methods like 'hot-wiring.' This involves crossing the wrong wires within the wiring of a vehicle, which fools the ECU into thinking the appropriate fob or key is being used. But, this technique is pretty risky and requires a lot of experience to accomplish it without damaging yourself. Modern car thieves are also employing more sophisticated methods, like Bluetooth or other specialized apps to obtain information about a vehicle and remotely control it remotely.
Car owners will often get warning lights that indicate the immobiliser has gone off the rails. It can occur for a variety of reasons, but the most common is a faulty or dead battery in the key fob. This problem can be fixed by an easy replacement.
If this isn't working, the transponder chip might be defective or mismatched with the ECU. This is harder to determine and fix since it may require a professional locksmith or dealership. However, a car's immobiliser can be damaged by water intrusion, or even being pulled away from the fob or key. If any of these issues occur it's a good idea visit a local garage or car dealer for assistance.
