Few questions about Lockpicking

[Malheki]

1) If you are stealthed and one tile away and double click a chest you just unlocked a) will it reveal you and b) will it kill you if its trapped?
2) If stealthed and you are next to the chest can you loot without revealing?

Im currently macroing my lockpicking so i have not been able to test this which is why im asking

With treasuremaps having their own mechanics. 4 tiles away to not explode yerself when opening and looting will reveal.

Lvl 4 dungeon chests and lower 1 tile away and you sont die. it will not reveal you but the big boomm will give ye away:P unless if ye have detect hiden and remove trap. and you can loot without revealing
