If the immo lock you must wait 1hr with ignition on.

It happened to me aswell and the solution was to open the immobilizer and resoldering the pins of the oscillator and all of the components around it.

When you have no communication to imo* check if you can talk to other modules . I had same problem and it was a bad right front door module.
