Transponder Chips
Transponder chips are likely to be found in cars manufactured within the last 20 years. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
When activated by an electro-magnetic field the chip emits a low level signal. The signal is then taken up by an antenna that is attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip inside the key is the right one for the car you have.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will be taken up by the chip and cause it to send a signal back to the car. If the onboard car computer recognizes this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to start.
If the vehicle 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 feature is designed to deter people from trying to hack into the vehicle, however it isn't a foolproof security measure.

Key fobs communicate with each with the car via radio frequencies that are transmitted through an antenna in the center of the key. This signal is encrypted to block other key fobs from stealing or modifying the signal.
There are a few different ways to program a key fob depending on the vehicle's model and make. Some cars allow you to do it yourself. However, the majority of newer 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 sends signals to the receiver in the car that it is paired. The receiver then compares this information with the 'allowed' signals in the fob and then either locks or opens the door. If the information doesn't match, a chirping sound is heard and the car isn't permitted to function.
After the car has been associated with a particular fob, it only accepts signals from the device. As a result, other fobs won't be able to work with the vehicle even though they look the same. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that is only available in the dealer's service department. key programing from the aftermarket, especially those from older models with less advanced systems, can be programmed without the need for a dealer.
