It's a small plastic thing inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle. When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your particular car. This is what prevents hot-wiring or tampering with the ignition system of the vehicle to turn it on. http://pattern-wiki.win/index.php?title=currancole6737 inside the key confirms that the owner is the one who owns the vehicle.

There are a variety of cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe. When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will be absorbed by the chip and cause it to send a signal back to the car. If the computer on the car recognizes this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to start. If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and alert you with flashing lights and an alarm. This feature is designed to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined thief could still bypass this system by using a specific device that blocks the signal. As you can see, there are quite a number of benefits to having transponder keys.

Key Fobs In addition to locking and unlocking doors, launching the car remotely, or making sound chirps to help locate the car in a parking lot Key fobs today can also turn on the heated steering wheel or roll down all of the windows with a single push. These additional features could make it difficult to find your car keys. Key fobs communicate with each other and the car using radio frequencies which are transmitted via a small antenna located in the center of the key. This communication is encrypted to prevent others from intercepting or replicating the signal. There are a few different ways to program a key fob, based on the vehicle's model and make. You can sometimes do this yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob. When you press the button on a key fob the microchip sends an indication to the receiver inside the vehicle with which it is linked. The receiver then compares the data with the permitted signals stored in the key fob and then it opens or closes the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to function. When a car is connected with a specific fob, it will only accept signals from that specific device. Other fobs won't work with the car, even if they appear identical. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorised key fobs from taking control over it. Most dealerships with newer cars will only work with cars that have original fobs or genuine replacements offered by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security knowledge that is only available in the dealer's service department. Certain aftermarket fobs, typically those for older models that have less advanced systems, can be programmed without the need for a dealer.
