Using a Key Programmer
Modern key fobs aren't just keys. They communicate with a vehicle to start it, open the rear hatch, and more. To accomplish this, they have to be programmed together.

What is a key programmer?

This process is often required when a key or fob is lost or stolen. The device basically reprograms the digital signature of the chip inside the key to match the signature of the vehicle and allow it to start.
Certain cars are equipped with electronic immobilizers that prevent theft by stopping the engine from running without the right key. The system checks to see whether the fob or key is digitally signed. If it does not then the system will shut down. This kind of system has been found to be effective in reducing automotive theft and has been made mandatory for many models of cars by the manufacturer.
These anti-theft systems can be controlled by a module that is installed in the vehicle's engine compartment or instrument panel or ignition lock. In some cases the modules require specific keys that are specifically created by an expert to work with the anti-theft system. This is typically done by a dealership or locksmith through computers.
Although it is possible to reprogramme some fobs and keys at home, it is not recommended unless you are a highly experienced automotive technician. A wrongly programmed key can cause the vehicle to not start, fail to run or even be destroyed. The majority of auto manufacturers have a specific procedure for programming keys.

Dealers typically require the VIN number of your vehicle in order to do this, and will typically charge a fee to do it. You may be able to reduce the cost by providing the dealer a copy your title, which you can obtain through the DMV in the majority of states.

This type of programming should only be carried out by certified automotive technicians who have years of experience in electronic repairs.
