When I turn on camera and try to take picture i get message Card locked. How do I unlock card?

Is it an SD or SDHC card? 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 does’nt work please let me know as to further guide you. :D
