It is a tiny slide switch on the side of most memory cards, right on the edge.

Use a card reader to download your pics.

Remove the SD card from the camera. Slide the tiny switch on the side of the card to its other "unlocked" position. Reinsert the card in the camera.

But if you have already tried this, see this link for additional things that you can try.

Check to see if you have a foreign substance on the contactor in the camera.

If that doesn't work, try another card.
