Why train remove trap when a crappy telekenesis will remove it every time.

However, assuming you have the complimentary lockpicking ... you could follow the lockpicking guide and tour all of the dynamic chests in dungeons.

Pick the chest ... remove the trap ... next ... next ... next ... recall to the next location ... etc.

Another route could be to wax a bunch of paragons in Ilshenar (or miasma in the Labyrinth) take the chests and do the same thing ... pick the chest ... remove the trap.
