Transponder Chips
If your car was manufactured in the last 20 years, chances are it has a transponder inside of it. It's a tiny piece of plastic inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is taken up by an antenna attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip that is in the key is the correct one for the car you have.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to start it. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys appear like normal keys but have caps made of plastic. The chip is located inside the plastic portion of these keys. There are several different cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.
The circuit in the induction coil will emit signals when the transponder is put into the ignition barrel. The signal will be received by the chip, causing it to transmit a signal back to the car. If the onboard car computer recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as being the right one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined criminal could still be able to bypass this system by using a special device to take over the signal.
As you can see there are quite number of benefits to having transponder keys. All car owners should consider this in order to safeguard their investment and reduce theft risk.

Key fobs make use of radio frequencies to communicate with one another and the car. The frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted, which helps keep others from stealing and re-transmitting the signal.
There are a few different ways to program a key fob depending on the model and make. Certain models allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order for them program a replacement key fob, or an alternative one.
When you press the button on a key fob, the microchip sends an indication to the receiver inside the car that it is paired. The receiver then compares this information to the signals that are allowed 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 mobile car key programmer is linked with a particular fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, even though they appear like. This is to safeguard the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of 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 only place that has the experience to design a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
