Camera says "card locked" when I try to take a

in camera memory is alredy full but u say only memory card formaat pls look the camera memory and no answer that the card is full

What size is the memory card. If it's larger than 4GB then it won't work in the 5118.
Try using another card. Don't format it in your computer but do format it in the camera before trying to take pictures.

I know that you've also tried the tiny locking slide switch on the side of the card? But if so, the next thing to try is the lock switch in the camera itself. See the "toothpick fix" in this link.

Go into the menu and try to find "reset" to get back to factory default settings. If you can't, try this...remove the card and battery...press every button....leave it alone for 20 minutes....insert the battery and the card....turn it on.

SD type cards have a little switch on the card that can write protect or "lock" it. Take the card out of the camera and check this switch. To unlock it, it should be moved towards the edge of the card which has the electrical contacts.

SD and SDHC cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.
If that doesn't work, try another card.

Remove memory card from camera and slide lock in memory card (check photo).

Look at your memory card. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

SD card has a mechanial tab on the edge of the card to lock the card out to prevent accidental deletion of pictures by the camera . This tab had been accidently moved to the LOCKED position during CD card insertion/removal from the camera . Once tab had been returned to normal position . Every thing works fine now . JC
