Transponder Chips
If your car was manufactured in the last 20 years, chances are it has a transponder chip inside of it. It's a tiny plastic thing inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the ignition barrel. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.
This prevents the vehicle from starting by hot-wiring or tampering. The chip in the key also proves that you are the legitimate owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is contained inside the plastic portion of the key and there are different cuts that can be found on these keys: a regular standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit within the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer onboard the car is able to recognize the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.
If the
car key cut and program isn't able to recognize the transponder as the correct signal, it will not start the engine and alert you with flashing lights and a siren. This system is designed to deter people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined criminal may still be able to get around this system using a device that can detect the signal.

Key Fobs

A lot of these additional features might seem useful, but they can also make it more difficult to keep the keys to your
car keys cut and programmed.
Key fobs use radio frequencies to communicate with each other and the car. These frequencies are transmitted by a small antenna in the middle of the key. The transmission is encrypted, which helps stop others from stealing and replicating the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. You may be able to do it 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 a key fob, the microchip transmits signals to the receiver in the car that it is paired. The receiver compared this information to the 'allowed' signals stored on the fob and either locks or opens the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. This means that other fobs will not work with the vehicle, even though they appear similar. This ensures the security of the computer system that runs the car and blocks unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the expertise to prepare a replacement fob is in the service department of a dealer. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems can be programmed with out the need for a dealership.
