I know this is an older post I'm but just adding a bit of info about the EKA Code to help others in the future.

Thanks to No Doubt for this tidbit...
With a Foxwell NT510 multi system scanner, I was able to see and then change my 4 number EKA code (#3 EKA Programming in bottom right picture) to a code that I could remember...

Procedure for Programming a New or Non-Functional Remote:
New remote handsets even if ordered from the factory apparently have to be programmed/synchronized to the BECM by a special procedure formerly known only to dealers. Peter Marsh went through this dilemma when he purchased an official new remote for $147 from Land Rover (UK) and had to give them his VIN and Grandmother's maiden name. He got it to work by the following procedure: "Close the car. Insert the new remote in the drivers side lock pressing and holding the button with the lock symbol. Turn the key to the right as if locking, still holding the lock button down. Hold in this position for 3 seconds. Turn back to the centre position and pull the key out - STILL HOLDING THE KEY BUTTON. Once the key is out release the lock button. Whalla. Mine worked a treat after this." Wayne Gardam used the procedure from this section to get an old remote going again. When he purchased his Range Rover, one of its remotes would not work even after replacing the batteries, cover and keypad. The usual synchronization procedure had no effect. Search of net and owner's forums turned up a variety of suggestions from buying a new unit and getting the dealer to do it to turning in door for 10 seconds or placing in ignition etc. Finally, the procedure above worked first time! When Dan Foley got a new remote handset through the dealer, they wanted an extra $60 to program it, but he tried the above procedure himself and it worked perfectly.
