Transponder Chips If your car was manufactured within the past 20 years, it is likely that it has a transponder inside of it. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own. The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by the antenna that is attached to the ignition barrel of your car. This allows the vehicle's computer system to determine if the transponder chip in the key is the right one for your particular car. This is what stops hot-wiring or tampering with the ignition system of the vehicle to turn it on. The chip inside the key also confirms that you are the legal owner of the vehicle.

The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the computer on the car recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin. If the car does not recognize the transponder signal as the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from attempting to tamper with the vehicle, but it's not a 100% security measure. A skilled and determined thief could still be able to get around this system using a device that can intercept the signal.

Certain cars let you do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a new key fob or additional one. When you press the button on a key fob the microchip transmits signals to the receiver in 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 it opens or closes the car's door. If the information isn't in line, a chirping sound is heard and the car isn't permitted to operate. After the car has been paired with a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even though they look like. This safeguards the integrity of the computer system in the car and blocks unauthorized key fobs gaining control over it. The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the expertise to prepare an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
