Fortunately my service manager must have had a fighting heart and the security system transplant was all FOC, done under warranty, and came with a known EKA which was communicated nicely to me!
Regards telling the ECU that there is a new security module.... I think its actually the other way round. The various control units, like engine ECU and instrument controller, etc, need to announce themselves and be recognised by the Security module. (This comment coming from experience/observation during the installation of a new ECU as part of installing BAS tune - there is a process to get the security module to accept the new engine ECU - if I remember correctly).
As it took about a year to get an EKA code for my vehicle from Land Rover (eventually delivered via the complete security system replacement), and was thinking that I'd never get said EKA code.... I purchased a Nanocom EVO because the sales pitch indicates one can interrogate the security ECU to extract the EKA code, and more - can turn off the immobiliser.
(I figured that if I remembered to turn off the immobiliser before going into deep jungles - I'd be safe). 
Sadly the Nanocom EVO I bought has never managed to connect to my car at all and so (to date) a waste of my time and money. Blackbox are still (more than a year later) working on a solution to that. Maybe someday I will have a working Nanocom EVO, or will sell it!
