The reply to your reply: the lock is not more fragile, as the ice doesn't have a significant effect of that sort on particularly hard metals, and it even tightens the lock by covering open spots on the lock, as ice occupies more volume than common air. And also, having an E4 level Salamence go all out on a tiny space like that would definitely be a bad idea.
And you do know that there's no way to code things in order to have one of Shelly's pokemon named after the player character.
