EDIT: GiantCookieJar later discovered that the way this actually works is that, when you use a key on a lockjaw, it doesn't disappear. It just turns invisible and becomes unable to be bitten. However, the devs forgot to remove its collision for being remotely grabbed by Issun x 1000.

Unfortunately, this isn't useful for 2 reasons: Issun x 1000 is only available in the Imperial Palace, where there's only 1 key, and that keys are actually only usable on the doors to which they are assigned. Even if there were another lockjaw in the map, the retrieved key would not work. We know this from Moon Cave, where we can retrieve either key before using the other, and can see that neither works on the opposite Lockjaw.

Toward the end of the vid, I somehow got Issun to re-retrieve a key, even though I'd already used the only one in Imperial Palace. I have no idea how or why this happened. If this can somehow let us get the key without going all the way over to it, it would save time (maybe 40 seconds?) in runs that don't do fire tablet skip.
