It's a small plastic thing on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own. When activated by an electro-magnetic field, the chip emits a low level signal. The signal is then amplified by the specific antenna that is attached to the ignition barrel of your car. The computer system in the vehicle will then confirm that the transponder chip of the key is the right one for your car. This is the reason why hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car. Regular transponder keys are designed like regular metal keys with a plastic top. The chip is contained within the plastic part of the key, and there are different kinds of cuts available on these keys: a regular cut, a laser cut (also called a sidewinder) or Ford Tibbe key. When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the computer inside the car detects the signal as correct, it will disable vehicle immobilizer, allowing the engine to start. If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will notify you via flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an absolute security measure. A determined and skilled thief can still get around this system by using a specific device that detects the signal. You can see that a transponder is a great option. All car owners should consider this when they want to safeguard their investment and reduce the chance of theft. Key Fobs In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find the car in a parking space keys of today can also activate the heated steering wheel or roll down all of the windows with a single push. A lot of these additional features may appear convenient, but they can also make it harder for you to keep the track of your car keys. Key fobs use radio frequencies to communicate with one another and the car. The frequencies are transmitted by a small antenna in the middle of the key. The signal is encrypted to stop others from intercepting or replicating the signal. There are several ways to program a key fob based on your vehicle's model and make. Certain models allow you to do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob or an additional one. When you press the button on your key fob it transmits an encoded code to the car's receiver it is linked to. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then locks or opens the car door. If the information does not match the signals, the car will not be allowed to drive. When a car is connected with a specific fob it will only receive signals from that device. As a result, other fobs will not work with the vehicle, even though they appear similar. This ensures the security of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control of it. The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place with the experience to design a replacement fob is in the service department of a dealer. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems can be programmed without the need for a dealership.
