Also known as a 'chip key or a 'transmitter and responder' key, it is created to stop the engine from starting if a third party has the same key. It works by transmitting the radio frequency signal from the key to the immobiliser system in your car. If the code stored in the computer of the car matches the signal transmitted by the key the immobiliser will be disarmed and the engine will be able to start.

The key with the transponder chip can be referred to as a 'fob' or a "smart" key because it is more difficult to clone than a traditional mechanical key fob repair near me. It is possible to duplicate a standard key, but not a transponder key. Unlike the remote central locking element of a conventional key, that relies on battery power the transponder chip is powered by the infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.

To turn on the transponder, the ignition cylinder must be in the ON position. The ring emits a flash of IR energy that is picked up by the microchip inside the repair key. The chip responds with an individual code to the immobiliser of your car. The car remote key fob repair's computer compared the code stored in its memory to the one from the transponder chip, and if they match the engine will begin to rev.

If the immobiliser detects an unauthorised transponder, key or other device is being used, it will disable the engine and stop any of its vital components from working. The car will not move if the engine is not working. It would be easy for a criminal to hot-wire it and drive off.

If you do not take action and the security light on your vehicle will continue blinking, and you won't be able to begin it.

Security Light

The immobiliser is powered by a tiny battery that sends an electrical signal to the transponder chip within your key. This is an anti-theft device that stops anyone from driving your car without the correct key. If the system cannot detect a digital serial from the chip on your key, it will shut off the engine immobiliser to stop the car from starting.

The car immobiliser is a fantastic way to deter thieves, however it can sometimes get out of in sync. This could be due interference or a system that is too sensitive. If this is the situation, it could be necessary to reset. To do this, disconnect the battery. Leave it disconnected for about 15 minutes before reinstalling it and begin the car. This will reset the system and allow it to accept the key again.

The security light is the car immobiliser's method of letting you know that there's a problem with the system. If the light is on and you attempt to start your car, it is a sign that the code in the ECU does not match the chip inside the key. This could happen if have recently replaced your car key with one that was not programmed to the vehicle, or if you've had a bad swapped ECU.

Keep the key in this position for 10 minutes. The security light should come on, then turn off. If it doesn't, you will need to repeat this procedure and wait another 10 minutes. This should resolve the issue when you repeat the process three times.

Programming

The car immobiliser prevents the engine from running when the fob or key are not properly programmed. It is based on a specific RFID microchip that cannot be copied and has its own serial number. The immobiliser will be disengaged when it is unable to recognize the code. This is why it's so hard to beat.

Modern cars come with this system as standard. This makes it extremely difficult to connect the car to a hot wire or use a different key for starter. The system works by sending a code from the key fob to the ECU. The ECU then knows that it's the right key and that the code isn't compromised. The system will not allow the car to start if it doesn't receive the correct code. Some models will even notify the owner if a person tries to use an unapproved fob or key.

The system is not 100% secure, however. Some thieves have been able to get around the immobiliser using methods such as 'hot-wiring'. This involves using the wrong wiring in a vehicle in order to trick the ECU. This method is risky and requires a lot of expertise to avoid electrocuting yourself. Modern car thieves are also employing more sophisticated methods, such as Bluetooth or specialised apps to steal a car's information and remotely control it remotely.

Owners of cars will often notice warning lights that signal an immobiliser gone haywire. It can happen for many reasons but the most frequent one is a faulty battery in the keyfob. The issue can be solved by a simple replacement.
