Hello
I had the same problem about 6 months ago with the key not working at a gas station. In my case I knew exactly was was going on, as the key after insertion would not turn at all. After some jiggling with the key's guts (it pays to know the problem area) The car started, and I was on my way.
In my case, it was a bad key, in your case, if the EIS was replaced /reset, it first goes into test mode (no authorization required), and if not activated by the technician, after so many starts, it will end the test mode with no further authorization to start the car.
Since you now have a new EIS and a new key (if I understood correctly), the new EIS will have to match with the ESL (steering lock) as well as the ECU (the engine computer). When you insert the key, the EIS sends an unlock message with authorization code to the ESL, and if the ESL likes the authorization code, it will unlock the steering and sends and acknowledgement to the EIS. EIS will then release the key turn lock, allowing you to turn the key to start the car. It is odd that the EIS will allow you to turn the key without getting and acknowledgement from the ESL. It appears that the ESL is unlocked, and never receives a lock command when the key is turned to OFF and removed.
What is the equivalent of IRZ and IZR modules in english ? Never heard them before.
What is the fault code associated with this ?
It appears that you have a start enable issue, while start is authorized initially, a communications issue causes it to be disabled.
