Thanks for the quick replies! My Nissan forum can take a day or two for a reply.
To take care of the key issue, I ordered a lock cylinder from Ebay. I'll have to get another key and have it programmed. From what I've read, everyone suggests having 3 on hand, so if one gets damaged, I can reprogram a 3rd with the 2 good ones.
Should arrive by the weekend. Then I can at least drive the car and work on the other issues.
