These tools are generally not accessible to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time. Other kinds of key programming can be performed by anyone.

This is because the key might not work properly, or it will not start the vehicle at all. This is because the new key has not been programmed into the vehicle's system, and this could be very costly. It is recommended to have two keys that work for the modern automobile so that you can program the replacement key whenever required. Keyprogrammers are devices which can reprogram the transponder chip on the form of a new key fob or mechanical key. It is also able to copy the data of an existing key and allow duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port).

It's the tiny piece of plastic in the head of your car key that contains 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 is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the car's computer system to determine if the transponder chip inside the key is the correct one for the car you have. This is what prevents hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip inside the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft. Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is contained within the plastic part of the keys. There are various cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe. When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the onboard car computer detects this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin. If the vehicle doesn't recognize the transponder signal as the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding an alarm. This is designed to discourage people from attempting to tamper with the vehicle, however it's not a 100% security measure. A determined and skilled thief can still get around this system using a special device that detects the signal. It is evident that a transponder is a great option. Every car owner should take this into consideration if they wish to protect their investment and minimize theft risk. Key Fobs Key fobs today can be more than just a way to lock and unlock doors. programming car key can also turn on the vehicle remotely, emit chirping sounds to help locate the car or turn on the heated steering wheel. A lot of these additional features might seem useful however they could make it harder for you to keep the track of your car keys. Key fobs communicate with each with the car via radio frequencies which are transmitted by an antenna that is located in the middle of the key. This signal is encrypted to block other key fobs from stealing or modifying the signal. Keyfobs can be programmed in different ways based on the model and brand of your vehicle. Certain models allow you to do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or an additional one. When you press the button on a key fob the microchip sends a signal to the receiver in the vehicle that it is paired. The receiver compares this information to the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function. Once the car is paired with a specific fob it will only receive signals from that device. This means that other fobs won't work with the vehicle even if they look the same. This ensures the security of the computer system of the car and prevents the use of unauthorized key fobs to gain control over it. Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security expertise which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those from older models with less sophisticated systems can be programmed with out the need for a dealer.
