Answer
You have replaced quite a few parts in hopes of solving the problem.  At some point, you have to decide to get the proper diagnostics.

If the security system has disabled the engine, it's never going to start until you remedy that.  If I were you, I would find someone with the proper specialist LR test gear and see why the vehicle is not running.  With the proper tester, this should not be a mystery.  You are either going to see some signal missing, or there is no authorization to run, or the ecu has failed.  

None of those issues can be untangled without a proper tester.
