Last night my pathfinder was broken into, and my wallet (containing my only FOB) was stolen. My good friend is an auto locksmith and came to reprogram me a new key. He told me that the computer wipes any previous codes, so the stolen FOB couldn’t work, but the emergency key might. What I just read about using the key because of a dead FOB battery it sounds like you would need the fob. Is that true, or do I need to worry about my car being stolen too?
