Key Fob Replacement and Reprogramming - Why Your Car Won't Start Most cars are equipped with an immobilizer that prevents car theft. If your vehicle doesn't start after inserting the key fob, there may be a problem with a transponder chip that is not sending a security code to the immobilizer system.

The chip transmits a passcode to the immobilizer unit of the car which can be integrated into the PCM, BCM, instrument cluster smart junction box or standalone module. The system then checks the code to make sure it is correct. If the code is incorrect it will disable the components that are essential to the start of the car, such as the ignition or starter motor. This makes the car nearly impossible to start if you don't have the right key. The immobiliser system has proven extremely effective at cutting down on car theft since it was first introduced.

The majority of the time an immobiliser that is not working properly is caused by the dying or dead key fob battery. click the next site can be identified with an easy diagnostic test. If the problem persists and continues to recur, there could be other causes of the car's irregular behavior, such as electrical problems or a wiring issue. If this is the case, it's recommended to have a professional diagnose and repair the issue. Transponder Chip In cars made after 1995, a small electronic chip, referred to as transponder is embedded in the head of your car key. Also known as a 'chip key or a 'transmitter & responder key, it is designed to prevent the engine from starting if another person has an exact copy of your car key. It works by sending an audio 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 deactivate the immobiliser and allow the engine to begin. The key with a transponder is also called a fob or a smart key, because it is more difficult to duplicate than mechanical keys. Using special methods, it is possible to copy a conventional car 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 must be turned to the ON position. The ring emits a flash of IR energy that is picked up by the microchip within the key. The chip responds by transmitting a unique code to the immobiliser in your car. The car's computer analyzes the code stored in its memory to the one on the transponder and when the two codes match it will start the engine. The immobiliser will shut down the engine in the event of an unauthorised key or transponder. It also stops any essential components of the car from functioning. The car won't move if the engine is not working. It would be easy for a criminal hot-wire it and then drive off. This is a powerful deterrent to crime, and is the reason why you should get your car key-immobiliser repaired as soon as you can in the event of a malfunction. If you don't take this action then the security light on your car will keep blinking, and you won't be able to begin it. Security Light The immobiliser uses a small battery to transmit an electrical signal to the chip that is in your key. This anti-theft device stops anyone from starting their car without the proper keys. If the system cannot detect an electronic serial number from the chip in your key, it will disable the engine immobiliser, which will stop the car starting. The car immobiliser is a fantastic method of deterring thieves, but it can sometimes get out of the sync. This can be due to interference or the system becoming too sensitive. This could require a reset. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes, then insert it and start the car. This will reset the system and allow it to accept your key again. The security light is the car immobiliser's way of telling you that there is a problem with the system. If you try to start your car and the light is solid on it means that the chip inside your key isn't in sync with the code stored in the ECU. This can happen if you have recently replaced the car key with a different one that has not been programmed to the vehicle, or if you've had a bad swapped ECU. If this is the situation you should take your transponder or key chip to a professional to have them correctly programmed for the vehicle you are driving. It's possible that your system will not accept the key due to a software upgrade or bug. To test this put your key in the ignition and switch it to the ON position but don't try to start the engine. The key should remain in this position for ten minutes. This will cause the security light to turn on and to go off. If it doesn't work, you'll need to repeat the procedure and wait another 10 minutes. This should solve the issue If you repeat the procedure three times. Programming A car immobiliser prevents the car's engine from operating without a correctly programmed key or fob. It is based on a specific RFID microchip that cannot be duplicated and comes with its own digital serial number. The immobiliser will disengage in the event that it doesn't recognize the code. It's difficult to beat. Modern cars come with this system as standard. This makes it very difficult to hot-wire a vehicle or utilize a different key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU recognizes that it is the correct key and that there hasn't been a compromise in the code. The system won't allow the car to begin when it doesn't receive the correct code. Certain models will even notify the owner if they attempt to use an unapproved fob or key. The system isn't impervious to attack, but it is. Some thieves have managed to bypass the immobiliser using techniques like 'hot-wiring'. This involves crossing the wrong wiring in a vehicle in order to trick the ECU. However, this is quite risky and requires a great deal of knowledge of how to accomplish it without cutting yourself. Additionally, many modern car thieves have switched to more sophisticated methods like using specialized apps or Bluetooth to hijack a car's data and remotely control it via their phone. Car owners often see warning lights that indicate an immobiliser that has gone out of control. It can happen for a variety of reasons however the most common one is a faulty battery in the keyfob. A simple repair should resolve this problem. If this isn't working the transponder chip could be defective or not compatible with the ECU. It is more difficult to fix and diagnose, as it can involve an expert locksmith for cars or a dealership. However, a car's immobiliser may also be damaged by water ingress or even physically being pulled away from the fob or key. If you encounter any of these issues it is a good idea to visit a local car dealer or garage for assistance.
