Transponder Chips Transponder chips are likely to be found in cars manufactured within the past 20 years. This is a little piece of plastic on the back of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle. The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your vehicle. This prevents the vehicle from starting by hot-wiring or altering the key. The chip in the key also confirms that you are the legal owner of the vehicle. This helps to prevent car theft. Transponder keys resemble normal keys but have caps made of plastic. The chip is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key. A circuit inside the induction coil will emit signals when the transponder is put into an ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the computer onboard 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 being the proper signal, it won't start the engine and will alert you with flashing lights and an alarm. This feature is designed to discourage people from trying to alter the vehicle, however it is not a foolproof security measure.

The communication is encrypted, which helps to prevent others from intercepting and replicating the signal. You can program a keyfob in various ways based on the model and make of your car. It is possible to do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or a second fob. When you press the button on a key fob the microchip sends signals to the receiver inside the car that it is paired. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then locks or opens the car's door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate. Once the car is linked with a particular fob, it will only accept signals from the device that is associated with it. In turn, other fobs will not work with the vehicle, even though they have the same appearance. This protects the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle. Most newer car dealerships will only accept vehicles that have original fobs, or genuine replacements supplied by the manufacturer.
