If all electronics are dead in the vehicle check and make sure all battery cables and cable connections are clean and tight with no issues.If this is all o.k. and you do have some electrical components operating properly this may be a fault with the electronic ignition switch itself with it needing replaced.I have seen it fail before internally causing this fault here.This will have to be tested further to be sure this is the cause here.
