With the card out of the camera you will see a small tab on 1 side that moves from front to rear. That's the lock so slide it to the other end of the slot. (it doesn't move very far).

First try the above tip from cicopo to see if that corrects the problem. If not, the following video provides additional troubleshooting steps for this particular problem. Would recommend trying these only for cameras that are out of warranty, or who's cost of professional repair would be more than the value of the camera:

There is nothing in your camera that is responsible for the card locked error it is the card. If you have moved the tab on the card to the unlocked position and you still hav that error message your card is at fault. Try a different card.

I did some more research on the SD card lock and it seems I spoke to soon. Of course if you solved your problem already then disregard this or read it for future reference.
Here's what I found...there is a small switch in the card reader that sense the lock switch position. The lock switch on the card is just a piece of plastic with no influence on the card itself only the reader.
I would say test the card in a computer first now and see if ot works. Also an old or worn out lock switch might change position as it is inserted into the reader.
Inspect the card slot with a light and magnifying glass paying strict attention in the reader where the lock switch would be located when inserted. Maybe something had gotten into the reader, perhaps blow it out with compressed air.
