How to permanently disable the nissan altima 2006 inmobilizer system?

I Just brought a Nissan Altima 2006 with 50k miles, drive it the first day and behave just like new. The second day It didn't start, i got only one key. I assumed the key is not working well, so it activates the inmobilization system that prevents the car to start. I wish somebody knows how to deactivate this system, so I get rid of the problem forever.|||Sorry but you can't. Get a new key that works properly.
