Infinity (Nissan) used different makers of their remote systems. If yours is a smart key unit it gets interesting as the smart fobs look alike but are not interchangeable. As this all started when you tried to add a different remote I would recommend having an automotive locksmith take a look. They can test the fobs and reprogram the system directly and see if they are the problem or if it is something else. A dealer can do this as well but generally the smith will be cheaper.
