Help with a mitsubishi galant immobilizer

Good afternoon friends Nesecito of his wisdom fixed a mitsubishi galant 3.0 2001 but my chip was lost because I came apart from the key someone could tell me how to deactivate the immobilizer since I made the fight but I do not give me injection pulse and then it is because of the immobilizer I urgently have you apologize.

What you ask is illegal, you have to go to the Mitsubishi house and ask for a key or chip with the chassis number and vehicle documentation.
