Transponder Chips
Transponder chips are likely to be found in cars manufactured in the last 20 years. It's a tiny plastic thing in the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your particular car.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the car key ensures that the owner is the person who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys resemble regular keys made of metal, but with caps made of plastic. The chip is inside 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 a Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the computer in the car detects the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine and will alert you with flashing lights and a siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief could still bypass this system with a specially designed device that detects the signal.
As you can see there are quite number of advantages to having a transponder key. Every car owner should take this into consideration in order to safeguard their investment and reduce theft risk.
Key Fobs

These extra features can make it difficult to find your car keys.
Key fobs use radio frequencies to communicate with each other and the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal.

When you hit the button on a key fob it transmits an informational code to the car's receiver that it is paired with. The receiver compared this information with the 'allowed' signals stored on the fob and either locks or opens the door. If the information doesn't match, the car will not be allowed to operate.
Once the car is paired with a specific fob, it can only receive signals from that device. As a result, other fobs won't be able to work with the vehicle even though they have the same appearance. This protects the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most newer car dealerships will only deal with cars that have original fobs, or genuine replacements sold by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. Certain aftermarket fobs, typically those for older models with less sophisticated systems, can be programmed without the need for a dealer.
