I have a samsung camera wb150f a card was locked. how can i fix it and recover it?

If its electronically locked you can not unlock
you need to replace card
try to format if format not works try to format different programs
if still same electronically locked replace with new one

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