K is for the Keys!

Another lazy post. Six (from twenty) unusual keys from the Towers of Krshal booklet. Buy it if you don't have it yet! Roll d6:

1. Bone Triangular Key. Opens doors to any morgue and crypt. 
2. Red Crystal Key. Can open every lock but after d6+1 usages it explodes, causing 2d8 damage. 
3. Golden Lock Pick. Jams every lock. 
4. Iron key of Giants. About 12” long. Can open every lock but only if it can fit into it. 
5. Black Iron Key. Has small ruby which glows if lock is protected by a trap. 
6. Platinum Triangle Key. Hums if lock is magical.
