Transponder Chips If your car was built in the past 20 years, then it has a transponder inside of it. It's the tiny plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your vehicle. When activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the car's computer system to confirm that the transponder chip inside the key is the correct one for your particular car. This stops the vehicle from being started through hot-wiring or altering the key. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to prevent car theft. Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is contained inside the plastic portion of the key, and there are a few different kinds of cuts available on the keys: a standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key. A circuit within the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer on the car detects this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin. If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will warn you with flashing lights and an alarm. This system is designed to deter people from tampering with the vehicle. However, it is not an unbreakable security measure. A determined and skilled thief could still evade this system using a special device that intercepts the signal. You can see that the transponder is a good option. Every car owner should take this into consideration if they wish to protect their investment and minimize the risk of theft. Key Fobs In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking lot keys of today can also turn on a heated steering wheel or roll down all windows with a single click. Many of these extra features might seem useful, but they can also make it harder for you to keep the keys to your car. Key fobs use radio frequencies to communicate with each other and with the car. The frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal. You can program a keyfob in different ways based on the model and make of your car. It is possible to do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or a second fob. When you press the button on your key fob it transmits an informational code to the car's receiver it is linked to. The receiver compares this information with the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information doesn't match the fob's information, the car won't be allowed to run. Once the car is linked with a specific fob, it will only accept signals from that specific device. Other fobs will not work with the car, even if they look identical. This protects the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle. The majority of newer dealerships will only deal with cars with original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that can only be found in the dealer service department. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems can be programmed without the need for a dealer.
