It's the tiny plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle. When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is received by a specific antenna attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip in the key is the correct one for your specific vehicle. This prevents the vehicle from being started by either hot-wiring or by altering the key. The chip inside the car key confirms that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car. Regular transponder keys are designed like regular keys and have a plastic top. The chip itself is housed within the plastic part of the key, and there are different kinds of cuts available on these keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key. When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer inside the car detects the signal as correct it will turn off the car immobilizer to allow the engine start. If the car doesn't recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and siren. This is designed to discourage people from attempting to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined thief could still bypass this system using a special device that intercepts the signal. As you can see there are quite few advantages to getting transponder keys. Every car owner must take this into consideration in order to safeguard their investment and decrease theft risk. Key Fobs In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate the car in a parking space keys of today can also turn on a heated steering wheel, or roll down all of the windows with a single push. A lot of these additional features might seem useful, but they can also make it more difficult to keep track of your car keys. Key fobs communicate with each other and the car using radio frequencies which are transmitted via an antenna that is located in the center of the key. The transmission is encrypted, which helps to keep others from stealing and retransmitting the signal. You can program a keyfob in a variety of ways depending on the model and make of your car. Certain models allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one. When you press the button on a key fob, the microchip transmits signals to the receiver inside the car with which it is linked. The receiver compared this information with the signals that are allowed inside the fob, and either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to operate. Once the car is paired with a specific fob, it will only receive signals from that specific device. Other fobs won't work with the car, even though they appear similar. This helps to protect the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle. The majority of newer dealerships will only deal with cars with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is a dealer's service department. Some fobs from the aftermarket, especially ones for older models that have less advanced systems, can be programmed without the need for a dealership.
