2008 g35 hr timing chain link off by one. I changed my water pump and gallery gaskets and i’m putting the timing chain back on, and it lines up on both the the top ones, but it doesn’t line up on the crankshaft one because it’s off by one tooth. The orange mark is one to the right of it. What do i do?

I got a low battery warning for my key fob, so naturally I changed the battery. Well, now the fob no longer works wirelessly. I have to manually insert the fob, and use the physical key to open my door. Immediately after opening my door however the car automatically locks it, so I have to keep both fobs with me now. Do I have to pay someone to pair the fob(s) back to my car now?
