Locking bone base?

[Idaero Ace]

Sometimes, when I animate, I forgot to turn on the Auto Keying, so I changed the bone base and destroying all animation. Well, since I have backups, that doesn't destroy my model. But it waste my time, a couple days ago I forgot to turned it on, and when I animate a walk animation with only FK, I realized I didn't turn it on after I finished it

So is there any way to lock it?

There's no way to do it for simple riggs. So try to keep the habit of auto keying.
