Keyprogrammers can recode the transponder chip on an entirely new mechanical key or key fob. It can also clone data from an existing key to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with a computer. They also have a bidirectional user interface that works with an immobilizer system.

Transponder Chips
If your car is made in the past 20 years, chances are it contains a transponder chip within of it. It's the tiny piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the transponder chip of the key is the right one for your car.
This stops the vehicle from being started by hot-wiring, or by altering the key. The chip in the car key confirms that the owner is the person who is the owner of the vehicle. This will help reduce car theft.
Transponder keys resemble regular keys made of metal but have caps made of plastic. The chip is contained in 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 called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from running and will notify you by flashing its lights and sounding siren. This feature is intended to discourage people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and committed thief may still be able to bypass this system by using a special device to intercept the signal.
As you can see there are quite number of benefits to having transponder keys. All car owners must take this into consideration if they wish to protect their investment and minimize theft risk.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start the car remotely, emit chirping sounds to aid in finding the car, or turn on the heated steering wheel. These additional features can make it difficult to locate your car keys.

Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted via a small antenna located in the center of the key. The transmission is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. Certain models allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or an additional one.
When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver it is paired with. The receiver compared this information to the 'allowed' signals stored in the fob and then either opens or closes the door. If the data does not match the signals, the car will not be allowed to operate.
Once the car is associated with a particular fob, it will only accept signals from the device. Other fobs will not work with the car, even though they look similar. This is to safeguard the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is a dealer's service department. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems, can be programmed without the need for a dealership.
