Transponder Chips
If your car was manufactured in the last 20 years, then it contains a transponder chip within 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 unique code for your car.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your vehicle.
This prevents the vehicle from starting by either hot-wiring or by manipulating. The chip in the car key verifies that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.
If the car does not recognize the transponder signal as being the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure. A determined and skilled thief can still get around this system using a special device that intercepts the signal.

Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start the vehicle remotely, make chirping noises to help locate a car, or turn on the heated steering wheel. A lot of these features may appear convenient, but they can also make it difficult for you to keep the track of your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted via a small antenna located in the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and retransmitting the signal.
There are a few different ways to program a key fob based on your vehicle's make and model. You may be able to do it yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or additional fob.
When you press the button on your key fob, the microchip inside transmits a code to the car's radio that it is linked to. The receiver compared this information with the 'allowed' signals inside the fob, and either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to function.
Once the car is paired with a specific fob it will only receive signals from that device. This means that other fobs won't be able to work with the vehicle, even though they appear similar. This is to safeguard the integrity of the car's computer system and prevent unauthorised key fobs from taking control of the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer's service department. Some fobs from the aftermarket, especially those from older models with less sophisticated systems, can be programmed without the need for a dealer.
