Break into locked chests?

As name says, is there a way to break into magicly locked chests using pistons or sth (i know how to break open doors, but not the chests :/ )

EDIT:
JESUS CHRIST GUYS, im talking about multiplayer -.-

I think there will be bosses and locked chests what you cant open before you kill boss in ruins...
(i think something like that will be added)

You can attempt to run the server out of memory, wherin the plugins will crash, although usually the server does as well. Sometimes on startup the plugins don't start correctly, and sometimes chest locking databases are wiped on crash.

tnt cannons

Certain plugins block explosions, but they don't block creeper explosions. Get a creeper

Obviously, but you basically said what I said by saying "most".
Creepers and TNT also have different triggers, thats why some miss it in their programming.
