Transponder Chips
If your car was manufactured in the last 20 years, then it has a transponder inside of it. This is a little piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is then taken up by the antenna that is positioned around the ignition barrel of your vehicle. The computer system in the vehicle will then confirm that the key's transponder chip is the right one for your vehicle.
This stops the vehicle from being started by hot-wiring or manipulating. The chip in the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.

The chip itself is housed within the plastic part of the key, and there are different cuts that can be found on these keys: a regular standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a 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 being correct, it will disable vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This is designed to deter people from trying to alter the vehicle, however it is not a foolproof security measure. A determined and skilled thief could still evade this system with a specially designed device that detects the signal.
As you can see there are quite a few advantages to getting transponder keys. This is something that all vehicle owners should think about if they want to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also turn on 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 however they could make it more difficult to keep track of your car keys.
Key fobs use radio frequencies to communicate with each other and the car. These frequencies are sent through a small antenna located in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
You can program a keyfob in a variety of ways depending on the model and make of your vehicle. You can sometimes do this yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits signals to the receiver in the vehicle with which it is paired. The receiver compares this information to the 'allowed' signals in the fob and then either opens or closes the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to operate.
Once the car is linked with a specific fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even if they look similar. This helps to protect the integrity of the car's computer system and to 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 that are supplied by the manufacturer. It is because the only place with the expertise to prepare a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need of a dealership.
