Mysteries

These are some things that I couldn't figure out. If anyone reading these has any clue what the answers are, please inform me. It would greatly be appreciated, and I can post up those clues for others as well.

1)How do you open the locked treasure chest in Kalm Town?
2)Is there a way to fix the sports car in Cid's house (3rd disk)?

Answers

I managed to get the item in the high shelf in Kalm by continuously trying to reach it (I had Tifa leading at the time) until she finally got annoyed and pulled it down.
