My camera is telling me the card is loc...

Remove the memory card from the camera if it isn't already, and look along the left edge of the card. Find a small tab and slide it forward (to the unlock position) and carefully slip the card back into the camera and try again. If it reports locked again, carefully remove the card to see if the tab has moved back to the locked position.

If the tab is moving to the locked position during the insertion process, you could place a small amount of tape along the card edge - over the tab - and carefully insert the card again. You might have to remove some tape to allow the card to fit into to slot. If you never lock the card - you could put a very small drop of super glue on the tab to hold it in place. Wait for the glue to set completely before inserting into the camera.

I hope this helps!
