This has nothing to do with the immobilizer though. The immobilizer authenticates the key. What you are seeing is called starter lock-out, and it is simply done with a relay in line with the starter wires on the key switch.

Unfortunately i dont have a manual and i dont know what model and make is the remote starter, although it was installed by toyota it could be aftermarket some people suggested here.

Yes and no. (if I start it right away or within approx 1 min after it shuts off, it will start. But if I wait over a min, then the engine will not start).
