Keyprogrammers are devices that can recode the transponder chip on an entirely new key fob or mechanical key. It also can clone the data of an existing key to make duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer and also provide an interface that works bidirectionally with the immobilizer system.

Transponder Chips
If your car was manufactured within the past 20 years, it is likely that it has a transponder chip inside of it. It's the small 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.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the chip in the key's transponder is the right one for your car.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip inside the key also verifies that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys appear like regular metal keys but they have caps made of plastic. The chip is inside the plastic part of these keys. There are various cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.
A circuit within the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer in the car detects the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. This function is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief might be able get around this system using a special device to intercept the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all vehicle owners should consider if want to protect their investment and reduce the risk of theft.

Key fobs today be more than just a way to lock and unlock doors. They can also start your vehicle from a distance, make chirping sounds to aid in finding a car or switch on the heated steering wheel. car key programming can make it difficult to locate your car keys.
Key fobs are able to communicate with each with the car via radio frequencies which are transmitted through an antenna in the center of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal.
There are a few different ways to program a key fob based on the make and model. It is possible to do this yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you hit the button on a key fob, the microchip inside transmits an informational code to the car's receiver that it is paired with. The receiver then compares this information to the 'allowed' signals stored on the fob and either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to run.
Once the car is paired with a specific fob, it will only accept signals from the device. In turn, other fobs won't work with the vehicle even if they look the same. This helps to protect the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because the only place with the expertise to prepare an appropriate replacement fob is the service department of the dealer. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need for an authorized dealer.
