Even remote start units from the mid 1990s had instructions on how to bypass the "smart key." Basically there is a resistor in the key that the ignition switch senses. The correct way to wire the system is to put a relay in the system that puts a resistor inline with the sensor when the car is controled by the remote start - the resistor drops out the rest of the time so that the system still works.
This is the explanation in the installation manual from my DEI remote start unit that I purchased in 1996 or 1997. I'm not sure that the Infiniti system works with the same method, but I suspect it does.
I echo Brian's comments about checking with other installers. What you describe sounds like a half-a$$ shortcut.
