This is a little piece of plastic inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle will then confirm that the transponder chip of the key is the correct one for your car.This prevents the vehicle from being started through hot-wiring or manipulating. The chip in the car key confirms that the owner is the one who owns the vehicle. This can help to reduce car theft.Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a regular cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.A circuit within the induction coil emits an electrical signal when the transponder is inserted into ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.If the vehicle doesn’t recognize the transponder as a valid signal, it won’t start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from attempting to hack into the vehicle, however it’s not a 100% security measure. A skilled and determined thief can still get around this system with a specially designed device that blocks the signal.As you can see, there are quite a number of benefits to having transponder keys. Every car owner should consider this if they wish to protect their investment and decrease theft risk.Key FobsIn addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find the car in a parking space, today’s key fobs can also activate a heated steering wheel or open all windows with just a single click. A lot of these additional features may appear convenient however they could make it difficult for you to keep the track of your car keys.Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. This communication is encrypted to block other key fobs from stealing or stealing the signal.Keyfobs can be programmed in different ways based on the model and make of your vehicle. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a new key fob or an additional one.When you hit the button on a key fob it transmits an encoded code to the car’s receiver that it is linked to. The receiver then compares the data with the permitted signals stored on the key fob and then locks or opens the car’s door. If the data does not match the signals, the car will not be allowed to run.Once the car has been paired with a specific fob, it can only receive signals from that device. In turn, other fobs will not work with the vehicle, even though they have the same appearance. This safeguards the integrity of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control over it.The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer’s service department. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems can be programmed without the need for a dealership.
