The chip emits an unintentional radio signal when it is activated by an electromagnetic field.

The circuit in the induction coil emits a signal when the transponder is placed in the an ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car detects the signal as being correct it will turn off the vehicle immobilizer to allow the engine start. If the car isn't able to recognize the transponder as a valid signal, it will not start the engine, and will notify you via flashing lights and an alarm.

These frequencies are transmitted by a small antenna inside the middle of the key. This signal is encrypted to prevent others from intercepting or replicating the signal. Keyfobs can be programmed in different ways based on the model and brand of your car. You may be able to do it yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or a second fob. 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 compares the information 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 connected to a specific fob, it only accepts signals from the device. As a result, other fobs won't be able to work with the vehicle even if they look the same. This protects the integrity of the computer system in the car and blocks unauthorised key fobs from taking control over it. The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer.
