Hi KenSorry to say this isn't something that you can do without a scan tool with the correct program to break into the security system. Either the dealer is required or in some cases a mobile locksmith with the correct programming info can do.It's somewhat complicated on the car, first the BCM has to be read, then a number from that is put into the Nissan data base, this produces a code which is then put into the computer to open the security so the keys can be programmed.Sorry to have to give you the crappy word on this, but it's the truth.Please let me know what more I can do to assist you today. Also, please remember to rate my answer, Just Answer does not compensate me for my time and resources. Follow up questions are included in the price of your question.
