Using a Key Programmer
Modern key fobs aren't simply keys; they can communicate with a vehicle to start it and open the rear hatch, and so on. To do this, they need to be programmed together.

What is a key programmer?
A key programmer is used to reprogram the transponder in a key or fob for an automobile or truck, or any another vehicle. This is required when the new key or fob needs to be programmed. This is usually required when a fob or a key is lost or stolen. The device reprograms the chip within the key to match the digital signature of the vehicle, allowing it to start.
Certain vehicles come with electronic immobilizer systems that prevent theft by stopping the engine from starting if it is not equipped with the correct key or fob. This is accomplished by having the system verify that the key or fob has the correct digital signature. If it does not, the system will shut down. This kind of system has been proved to be effective in reducing the incidence of theft and was made mandatory for many models of cars by the manufacturer.
These systems can be controlled by a module installed in the vehicle's engine compartment, instrument panel, or ignition lock. In some instances the modules require special keys that have been designed by experts to work with the anti-theft system. This is usually done by a dealer or locksmith using computers.

This credential gives you access to an inventory of immobilizer and key codes, as well as information about the product. This allows you to swiftly and easily program and test new keys for customers. It also provides essential documentation and support that will help you with your day-to-day business operations.
