No, even though it seems like it at times you cannot dead end yourself like that.

Which "dark dungeon"? You mean the Shadow Temple (or perhaps the Water Temple, since many people seem to have trouble with that temple)? In any case, if you're out of small keys, but there are still other small keys left in the dungeon, look at your dungeon map, and if you have the compass, you'll be shown the location of any remaining small keys. If there are no small keys left, it's likely that the only thing left to do is get the Boss Key. If you haven't gotten that yet, your compass will show where it is. Once you have the Boss Key, the only thing left to do is to go to the boss room and face the boss.
There are many keys that need to be found in order to complete Spirit Tracks. You'll need to be more specific, please.
I'I'm sorry but you have to be more specific because their are many dungeon keys throughout the game
which puzzle? There are many different puzzles in this temple so I'm not sure which one you are talking about.
There are many Dekus in Zelda...
Legend Of Zelda: 2 Quests. Zelda II, The Adventure Of Link: 1 Quest.
Almost every modern piano has 36 black keys and 52 white keys for a total of 88 keys in all.
Honestly Zelda is kind of in a category entirely of it's own there are not many games like Zelda out there
