A keyprogrammer is a device that can recode the transponder chip into an entirely new key fob or mechanical key. It is also able to clone information from an existing key which allows duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port).

Transponder Chips If your car was manufactured in the last 20 years, it is likely that it has a transponder chip inside of it. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car. When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then taken up by the antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car. This stops the vehicle from being started by either hot-wiring or by altering the key. The chip inside the car key confirms that the owner is the one who owns the vehicle. This will help reduce car theft. Transponder keys look like normal keys, but with caps made of plastic. The chip is located inside the plastic portion of the keys. There are a variety of cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe. When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will then get received by the chip, causing it to send a signal back to the car. If the computer in the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start. If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will warn you with flashing lights and a siren. This function is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief might be able bypass this system by using a special device to intercept the signal. You can see that the transponder is an excellent option. This is something that all car owners should consider if want to safeguard their investment and reduce the risk of theft. Key Fobs In addition to locking and unlocking doors, launching the car remotely or making noises to aid in finding a car in a parking lot keys of today can also activate a heated steering wheel, or open all windows with a single button push. These additional features could make it difficult to locate your car keys. Key fobs utilize radio frequencies to connect with one another and with the car. The frequencies are transmitted by a small antenna in the middle of the key. The transmission is encrypted, which helps to keep others from stealing and replicating the signal. There are a few different ways to program a key fob based on the model and make. It is possible to do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob. 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 compares the information with the 'allowed signals' stored in the key fob, and then locks or opens the car door. If the data does not match the signals, the car will not be allowed to operate. Once the car is paired with a particular fob, it will only receive signals from that device. This means that other fobs won't be able to work with the vehicle even if they look the same. This protects the integrity of the computer system that runs the vehicle and stops unauthorised key fobs from taking control over it. Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise that can only be found in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need of a dealership.
