There is very little in the that is particularly mathematical, just some basic addition, subtraction and division. All you need to do is to follow along with what looks like fairly simple written instructions. Besides, there is a step in there about choosing the"fob type" which we would have no idea about. And it sounds like you have to do a bit of trial and error with that fob type anyway.

I'd suggest having a go at following the instructions and if you get stuck at a particular point, ask a specific question here.

Thank you for the help. The fob type is just the location where it was distributed which is North America and the symbol for it is J. Ok thanks again I appreciate any help I will see how it works.

These two are an example of what I am trying to get these are programming codes without these I can not bring my key fob to dealer to program it for my Land Rover discovery. So I need those two bar codes figured out before I go to a Land Rover dealership. Thanking anyone who could get me the two bar codes correctly again the character keys are 2248CE.
