The smallest nuclear bomb available if unmaintained(deliberately by it's seller by the way) would most likely end up exploding with very little force and leave a dirty mess for a few blocks in every direction based on the wind.

You'd be lucky to break the glass in a storefront where it was placed.

Now if it's yield and power was maintained for the life of it's manufacture date, that's a different scenario.

Outside of my casual knowledge and HS/college intro courses, I'm not too much of an expert on electronics and phsyics. You mentioned that a un-maintained nuclear bomb would still go off, but would cause little damage. Please explain. Is it that the detonator goes off but the nuclear portion doesn't blow? Or that because some of the detonators don't go, due to not being maintained, you don't get the proper nuclear chain reaction?
