When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your car. This allows the car's computer system to determine if the transponder chip inside the key is the correct one for your specific vehicle.

This stops the vehicle from being started through 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 the possibility of theft from your vehicle.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer on the car recognizes this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to start.

If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and will notify you via flashing lights and a siren. This function is designed to discourage individuals from tampering with the vehicle. However programming keys isn't an absolute security measure.

When you press the button on your key fob the microchip inside sends an informational code to the car's receiver it is linked to. The receiver compares the information with the 'allowed signals' stored in the key fob and then opens or locks the car's door. If the information does not match, the car will not be allowed to operate.

When a car is connected with a specific fob it will only receive signals from that specific device. Other fobs will not work with the car, even though they look similar. This protects the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.

The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer.

However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for an authorized dealer.
