I own an Ibanez RG350EX. I recently bought a new tuner, seeing as I haven't tuned my guitar in a while I figured a take the locknuts off and use the knobs on the headstock. I have never messed with the locknuts and two of them were rounded so I couldn't get them off. So I'm asking what I should do to get this fixed.

Are they stripped? if you can get a grip of it with needle nose pliers, you MAY be able to jostle it loose, if not i dont know what you can do.

But after that see if you can get some new locks because it may be a hassle to do that every time...
