Transponder Chips
If your car was manufactured within the last 20 years, it is likely that it has a transponder chip inside of it. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your car. This allows the vehicle's computer system to verify that the transponder chip in the key is the correct one for your particular car.
This stops the vehicle from being started through hot-wiring or manipulating. The chip in the key also proves that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys resemble regular metal keys, but with a plastic cap. The chip is located inside the plastic part of these keys. There are several different cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
The circuit in the induction coil emits a signal when the transponder is placed in the an ignition barrel. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the computer onboard the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the right one, it will keep the engine from running and will notify you by flashing its lights and sounding siren. This is designed to discourage people from attempting to alter the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal can still get around this system using a special device that blocks the signal.

Key fobs use radio frequencies to communicate with one another and the car. The frequencies are transmitted by a small antenna within the middle of the key. This communication is encrypted, which helps keep others from stealing and replicating the signal.
You can program a keyfob in different ways based on the make and model of your car. It is possible to do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press a key fob's button, the microchip inside transmits a code to the car's receiver it is linked to. The receiver compared the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car's door. If the data does not match, the car will not be allowed to drive.
After the car has been associated with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, even though they look identical. This safeguards the integrity of the computer system that runs the car and prevents 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 because the process of creating the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer service department. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems can be programmed with out the need for a dealership.
