Transponder Chips
If your car was built in the last 20 years, it is likely that it has a transponder inside of it. This is the little plastic piece in the head of your
programing car keys key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
When activated by an electro-magnetic field, the chip emits a low level signal. This signal is then absorbed by the special antenna that is attached to the ignition barrel of your car. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the right one for your particular car.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to start it. The chip in the key also confirms that you are the legitimate owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are designed like regular keys, but with a plastic top. The chip is contained in the plastic portion of the key, and there are a few different types of cuts on these keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer on the car recognizes this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as being the proper 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, however it isn't a foolproof security measure. A skilled and determined criminal may still be able to bypass this system by using a special device to detect the signal.

Key Fobs

Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
You can program a keyfob in different ways based on the model and brand of your vehicle. It is possible to do this yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on your key fob it transmits a code to the car's receiver it is paired with. The receiver compared this information to the 'allowed' signals in the fob and then either locks or opens the door. If the data does not match, the car will not be allowed to run.
When a car is connected with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, even if they appear similar. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it.
Most newer car dealerships will only deal with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because the only place with the expertise to prepare a replacement fob is in a dealer's service department. Some aftermarket fobs, usually ones for older models that have less advanced systems can be programmed with out the need for a dealership.
