Transponder Chips
Transponder chips can be found in cars that were manufactured in the last 20 years. It's a small plastic thing inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for your particular car.
This prevents the vehicle from starting by hot-wiring, or by tampering. The chip in the key also proves that you are the legal owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys look like regular keys made of metal, but with caps made of plastic. The chip is contained in the plastic portion of the key and there are different kinds of cuts available on these keys: a standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer onboard the car is able to recognize the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine, and will warn you with flashing lights and siren. This feature is designed to deter people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and committed thief might be able bypass this system by employing a device designed to intercept the signal.
As you can see, there are quite a number of benefits to having a transponder key. All car owners should consider this if they wish to protect their investment and decrease the chance of theft.
Key Fobs

These extra features can make it difficult for you to find your car keys.

There are many ways to program a key fob depending on the vehicle's model and make. You may be able to do it yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on your key fob the microchip inside sends an informational code to the car's receiver 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 information isn't in line an chirping sound is heard and the car isn't able to operate.
Once the car is connected to a specific fob, it will only accept signals from the device. Other fobs won't work with the car, even if they look identical. This safeguards the integrity of the computer system of the vehicle and stops unauthorised key fobs from taking control over it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. The reason for this is that the only place with the knowledge to create the replacement fob is a dealer's service department. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems can be programmed without the need for a dealer.
