The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle can then verify that the chip in the key's transponder is the right one for your car.
This prevents the vehicle from being started by either hot-wiring or by tampering. The chip inside the key also proves that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will be absorbed by the chip and cause it to send a signal back to the car. If the computer onboard the car recognizes the signal as valid it will turn off the car immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and notify you via flashing lights and a siren. This is designed to discourage people from attempting to hack into the vehicle, however it's not a 100% security measure.

Key fobs communicate with one other and with the car through radio frequencies that are transmitted via an antenna in the middle of the key. The transmission is encrypted, which helps to stop others from stealing and re-transmitting the signal.
There are many ways to program a key fob based on your vehicle's make and model. You can sometimes do this yourself, but most newer vehicles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends an informational code to the car's radio that it is paired with. The receiver compared the information with the 'allowed signals' stored in 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 operate.
When a car is connected with a particular fob, it will only accept signals from the device that is associated with it. Other fobs will not work with the car, despite the fact that they appear identical. This protects the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
The majority of newer dealerships will only accept vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is because the only place that has the expertise to prepare an appropriate replacement fob is a dealer's service department. Some aftermarket fobs, usually those for older models that have less advanced systems, can be programmed without the need for a dealership.
