At lower levels you can get a key for about 10 energy units or less on average. Cheap non key rooms yield 3 to 5 keys per visit. Access key rooms 5 to 8 keys per visit. Thread, lanterns, tickets are best bets for key to energy ratio. After that, it's all down hill. Sometimes non key rooms are best bvet for good key to energy ratio, mayors office, cafe, ballroom, alley. I tossed in train station and marketplace for their collections. Good luck collecting. M.
