Good Question.. what you first need to do is Buy a transmitter that decodes the frequency of your key.

After you do that, you can either make your own USB cord or you can have one made for you. Once you have that, you can change the algarithom in the key to the frequency you need.

if you do it yourself and your good with computers then it would cost you about $9 to do, the price of the USB cord.

So the question is, how good are you at computing?
