Somewhere on the SD Card there should be a little switch on the edge of it that you can slide up and down. It controls the locking feature. Hope this helps.
But if moving the slide switch doesn't help, there are several other possible causes for "memory card locked", "memory card error", or "no memory card". Some include trying to use a 4GB SDHC card with an older camera made before SDHC format came out. Others include problems with the tiny slide switch on the side of the card, or the electrical contact switch internal to the camera. The problem may also arise from simple formatting problems if the card has never been formatted in the camera (note that this will also erase the card). Troubleshooting tips for this problem may be found at the below related link.
take out your sd card and look on the side of your sd card and you will see a little slider thing and it will tell you which way to unlock it and which way to lock and put on the side where it says to unlock it.
There should be a little white switch on the side of the card. Flick that switch in either direction (depending which) to unlock/lock your SD card.
the tab on the side
To unlock the slide lock on your SD card, simply slide the switch on the side of the card to the unlocked position. This will allow you to write, delete, and modify the data on the card.
On the left side of the SD card there is a small lock switch. Slide this into the upper position.
