Disco 2 cranks but doesn't start

I have a 2002 Discovery 2 V8 4.0 Motoronic Petrol. Sat for a yr. And bought battery, 2 ECM's still have original. Bought Nanocom, and SyncMate. I think I need to have the security codes the same in BECM and ECM. I know the EKA code but don't know how to see if they are the same or how to change them if they are not. I'm new to Landrovers really need help. Thank you so much.

Best to ask over in the disco section of the forum
