A keyprogrammer can recode a transponder chip on a new mechanical key or key fob. It can also clone the information from an existing key, allowing duplicates to be created. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software, which allows them to communicate with a computer.

Transponder Chips
Transponder chips can be found in cars that were manufactured in the last 20 years. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your vehicle.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to start it. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is contained within the plastic portion of the keys. There are various cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and will warn you with flashing lights and siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A determined and skilled thief could still evade this system by using a specific device that blocks the signal.
As you can see, there are quite a few advantages to getting a transponder key. Every car owner should consider this when they want to safeguard their investment and minimize the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to help locate the car, or switch on the heated steering wheel. These extra features can make it difficult to locate your car keys.
Key fobs communicate with one other and with the car through radio frequencies that are transmitted through an antenna in the middle of the key. The communication is encrypted, which helps to keep others from stealing and replicating the signal.
Keyfobs can be programmed in various ways based on the model and make of your car. Certain models allow you to do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or an additional one.
When you press the button on a key fob, the microchip sends an indication to the receiver in the car with which it is linked. The receiver compares this information to the signals that are allowed in the fob and then either opens or closes the door. If the information does not match, the car will not be allowed to drive.
Once the car is paired with a particular 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 appear similar. This is to safeguard the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.
Most newer car dealerships will only accept vehicles that have original fobs or genuine replacements sold by the manufacturer. This is because preparing a replacement fob requires technological and security skills that is only available in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
