So, I have the spare key to my neighbor's house.

I don't think it is advisable to have a spare key to your neighbor's house. It could put your neighbor in a difficult position if it is not safe to keep, and it also could create privacy issues between you and your neighbor. I'd recommend speaking to your neighbor to come up with an alternative plan.
