Altezza IS200 loss all keys

[ogip]

Hi,
My friend lost all he's keys for his Altezza IS200 1G-FE engine.
I know the engine won't start due to immobilizer even though he has a duplicate key (without transponder).

Is all the Altezza IS200 are equipped with immoblizer?
Can I use a Japanese ECU to be able to start the engine?

cheers,
Ogip
