My canon camera has been popping up with memory card locked when I've checked it several times and nothing works. I've tried a different memory card doesn't work either.
If card is definitely not locked with slider-switch on card, it can be caused by dirty contacts inside the card-slot and/or dirty contacts on the card.
Smear the contacts on the card with a small amount of hand cleanser, then insert & eject it several times in the slot.

Had same problem - finally cleared by using small shaver brush to clean card slot and blow out dust (although no dust evident!).
