A keyprogrammer can recode the transponder chip of the new mechanical key or key fob. It also can clone data from an existing key to make duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with computers. They also have a bidirectional interface to work with an immobilizer system.

Transponder Chips
If your car is made in the last 20 years, chances are it has a transponder chip inside of it. It's the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the correct one for your particular car.
This prevents the vehicle from starting by hot-wiring or altering the key. The chip in the car key confirms that the owner is the one who owns the vehicle. This will help reduce the possibility of theft from your vehicle.
reprogram car key look like normal keys, but with a plastic cap. The chip is inside the plastic part of the keys. There are various cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
A circuit inside the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer onboard the car is able to recognize the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and warn you with flashing lights and siren. This feature is designed to discourage people from attempting to hack into the vehicle, but it is not a foolproof security measure. A determined and skilled thief could still evade this system using a special device that blocks the signal.
As you can see there are quite a number of advantages to having a transponder key. Every car owner should consider this in order to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding cars, or turn on the heated steering wheel. These additional features could make it difficult to find your car keys.
Key fobs communicate with each 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 stop others from stealing and re-transmitting the signal.
There are several ways to program a key fob depending on the vehicle's model and make. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer to program a replacement key fob, or an alternative one.
When you press the button on a key fob the microchip sends a signal to the receiver in the car that it is paired. The receiver compared this information with the signals that are allowed in the fob and then either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't able to function.
After the car has been connected to a specific fob, it only accepts signals from the device. This means that other fobs won't be able to work with the vehicle even if they appear similar. This safeguards the integrity of the computer system of the car and prevents unauthorised key fobs from taking control over it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that can only be found in the dealer's service department. Some fobs from the aftermarket, especially ones for older models with less advanced systems, can be programmed without the need for a dealer.
