I think that you can ask the LR dealer to get you the EKA code if you give him the VIN number, and can prove its your motor, that at least would get you going.
Failing that you need someone with a Nanocom to plug it into your diagnostic socket then they can read off the EKA code.
If your fob is a two button unit you can pay LR ?42 or get one from the scrappy for a couple of quid. The same Nanocom will let you programme it.
I have just had 4 new fobs done total cost ?65 and that was a garage (not LR) doing the programming.
If you let folks know roughly where you are then someone with a Nanocomm might be close
