When activated by an electro-magnetic field the chip emits a low-level signal. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system of the vehicle will then confirm that the transponder chip of the key is the correct one for your car.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get received by the chip and cause it to transmit a signal to the car. If the computer on the car recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and will alert you with flashing lights and an alarm. This feature is intended to discourage people from attempting to alter the vehicle, but it isn't a foolproof security measure.

If the information doesn't match, a chirping sound is heard and the car isn't able to operate.
After the car has been connected to a specific fob, it can only receive signals from the device. This means that other fobs won't work with the vehicle, even though they have the same appearance. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control of it.

However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by customers without the need for an authorized dealer.
