Key Fob Replacement and Reprogramming - Why Your Car Won't Start

The immobiliser is powered through the transponder that is located in the fob, key or instrument cluster. The chip transmits a passcode from the fob or key to the immobilizer unit in the car. It can be integrated into the PCM (power control module) or BCM (brake control module), instrument clusters, smart junction boxes, or standalone modules. The system checks the code to make sure it's correct. If it's 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 proven highly effective in cutting down on car theft since it was first introduced. Even so thieves are always seeking ways to bypass these security measures.

Transponder Chip
A tiny electronic chip, called transponder, is embedded into the head portion of your car keys. The technology was introduced in cars made after 1995. It is also known as a "chip key" or a "transmitter-responder" key. Its purpose is to stop your engine from starting if you have the same key. It works by transmitting an audio frequency signal from the key to the immobiliser system in your car. If the code stored in the car's computer matches the signal transmitted by the key the immobiliser will then be deactivated and the engine will begin to run.
The key with the transponder can also be referred to as a "fob" or a "smart" key, as it is more difficult to copy than mechanical keys. It is possible to duplicate a conventional key, but not a transponder key. 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 that is transmitted through the antenna ring on the ignition cylinder.
To activate the transponder, the ignition cylinder needs to be in the here ON position. The ring emits a burst IR energy that is detected by a microchip within the key. The chip then sends an individual code to the immobiliser inside your car. The car's computer compares the code stored in its memory with the one from the transponder chip and If they are compatible the engine will be able to start.
If the immobiliser is able to detect an unauthorised transponder or key is being used it will shut down the engine and stop any of its essential components from functioning. Without a functioning engine, the car will not be able to move, and it will be easy for criminals to hot-wire the vehicle and drive away.

If you don't take this action and the security light on your car will keep blinking, and you won't be able to begin it.
Security Light
The immobiliser makes use of a tiny battery to transmit an electrical signal to the chip in your key. It is an anti-theft device that blocks anyone from opening your car without the correct key. If the system is unable to detect a digital serial number from the chip on your key, it will disable the engine immobiliser, which will stop the car starting.
The car immobiliser is a fantastic method to deter thieves, but it can sometimes be out of sync. This could be due to interference or the system is too sensitive. This could need an adjustment. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes then reinsert it and begin the vehicle. This will reset the key system to ensure that it is ready to accept your keys once again.
The security light is here an immobiliser's way of alerting you to an issue. If you try to start the car but the light stays on it indicates that the chip inside your key isn't in sync with the code that is stored in the ECU. This can occur when your car's key has been replaced with a new one that is not programmed to work with the vehicle, or when an get more info ECU has been swapped incorrectly.
If this is the situation you should take your transponder or key chip to a professional for them correctly programmed for the vehicle you are driving.

Modern cars come with this system as standard. This makes it difficult to wire a car or use a different key for starter. The system works by checking the chip in a key fob or key and sending a passcode get more info to the ECU (electronic control unit). The ECU is aware that it's the right key and hasn't be compromised code. The system will not allow the car to start if the doesn't receive the correct code. Some models will even report back to the owner in the event that someone attempts to use an unapproved fob or key.
The system is not 100% secure, however. Some thieves have bypassed the immobiliser using methods like 'hot-wiring.' This involves crossing the wrong wiring in an automobile to trick the ECU. This is a risky method and requires a lot of expertise to avoid electrocuting yourself. Modern car thieves are employing more sophisticated methods, like Bluetooth or specialised apps to steal a car's information and remotely manage it.
Car owners are often faced with warning lights that indicate the immobiliser is malfunctioning. This could be due to a variety of reasons, but one of the most common is a dead or defective battery in the key fob. The issue can be solved by a simple replacement.
