Multi Memory Card

Multi Memory Card
My memory card the camera says it is locked ….. Why?

I have a 10.1 megapixel Casio Exilim camera. The card Lexar memory I use is multi-use 4 GB SDHC. I recently uploaded photos from the memory card in my laptop and when I put the memory card to take some more photos, my camera screen said my memory card was locked! I do not know what happened or how to unlock it. But if anyone knows how to be much appreciated. Thank you! Oh. That was so simple! Lol. Thanks everyone!

Take the memory card. There is a small switch on the side. You only have to switch to unlock
