These tools are not generally available to the public and are only used by professionals. This kind of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time. Other types of programming car keys are much easier and can be done by anyone who is able to. These are usually done by using the onboard diagnostics port, which is accessible with the key-fob-programming device.

Key Programmers Modern vehicles require a key-programming method to initialize their vehicle's systems and then start the vehicle. In a number of cases keys must be configured by the dealer or an auto locksmith. This is because the key may not function correctly, or it will not start the vehicle at all. The reason for this is that the new key hasn't been programmed to the automobile's system. This can be quite expensive. It's best to have two keys that are compatible for your modern car so you can program the replacement key whenever needed. Keyprogrammers are devices that can recode the transponder chip in a new key fob or mechanical key. It also can clone information from an existing key to make duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system. There are many different types of keyprogrammers on the market. They come in all sizes, shapes, and colors. Some are inexpensive, while others may cost thousands of dollars.

Transponder Chips Transponder chips can be found in cars manufactured within the last 20 years. It's a small plastic thing in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle. When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is then absorbed by a special antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your car. This stops the vehicle from starting by hot-wiring, or by manipulating. The chip in the key also verifies that you are the legal owner of the vehicle. This will help reduce the possibility of theft from your vehicle. Transponder keys appear like regular keys made of metal, but with a plastic cap. The chip is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a cut laser cut (also called a sidewinder) or Ford Tibbe key. A circuit within the induction coil emits an electrical signal when the transponder is placed in the the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer inside the car recognizes the signal as valid it will turn off the 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 an alarm. This feature is intended to discourage people from attempting to alter the vehicle, however it isn't a foolproof security measure. A skilled and committed thief may still be able to escape this security system by using a special device to take over the signal. As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should think about if they want to safeguard their investment and minimize the risk of theft. Key Fobs In addition to locking and unlocking doors, starting the car from a distance or making sound chirps to help locate the car in a parking space Key fobs today can also switch on the heated steering wheel or roll down all of the windows with a single button press. A lot of these additional features might seem useful but they could make it harder for you to keep track of your car keys. Key fobs make use of radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located inside the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and retransmitting the signal. There are many ways to program a key fob depending on the model and make. You may be able to do it yourself, but the majority of newer automobiles require a locksmith shop or a professional 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 car with which it is paired. The receiver compared this information with the 'allowed' signals inside the fob, and either opens or closes the door. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate. When a car is connected with a specific fob it will only receive signals from the device that is associated with it. In turn, other fobs won't be able to work with the vehicle even though they have the same appearance. This protects the integrity of the computer system of the car and blocks unauthorised key fobs from taking control of it. Most dealerships with newer cars will only deal with cars that have original fobs, or genuine replacements offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge which can only be obtained in the dealer service department. Some aftermarket fobs, usually those for older models with less sophisticated systems can be programmed with out the need for a dealership.
