Keyprogrammers are devices that can recode the transponder chip on the form of a new key fob or mechanical key. It can also clone the data from an existing key which allows duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with computers as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips If your car was manufactured in the last 20 years, chances are it has a transponder chip inside of it. It's a tiny piece of plastic on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle. When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then absorbed by the special antenna that is fitted around the ignition barrel of your car. This allows the car's computer system to verify that the transponder chip in the key is the correct one for your particular car. This is what prevents doing hot-wiring or altering the vehicle's ignition system to start it. The chip in the key also confirms that you are the genuine owner of the vehicle. This can help to reduce car theft. Regular transponder keys are designed like regular keys, but with a plastic top. The chip is contained within the plastic part of the keys. There are a variety of cuts such as a standard cut laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe. When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will then get received by the chip, causing it to transmit a signal to the car. If the computer onboard the car detects the signal as being correct it will turn off the vehicle immobilizer to allow the engine start. If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will alert you with flashing lights and an alarm. This feature is designed to discourage people from trying to alter the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that detects the signal. As you can see there are quite a number of benefits to having a transponder key. This is something that all car owners should consider if want to safeguard their investment and decrease the chance of theft. Key Fobs Key fobs today be more than just a way to lock and unlock doors. They can also start your vehicle remotely, make chirping noises to aid in finding cars, or switch on the heated steering wheel. A lot of these additional features may seem convenient but they could make it harder for you to keep the track of your car keys. Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted by an antenna that is located in the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and replicating the signal. You can program a keyfob in different ways based on the model and make of your vehicle. You can sometimes do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or an additional fob. When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle that it is paired. The receiver then compares this information with the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to function. After the car has been associated with a particular fob, it can only receive signals from that device. Other fobs will not work with the car, even if they look 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 dealerships with newer cars will only deal with cars that have original fobs or genuine replacements 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. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by customers without the need of dealers.
