My digital lumix panasonic was been memory locked what shoud i do to unlocked?

Hello. Memory cards have a tiny lock switch on the upper left edge. check to see if it's in the locked position. If it is slide it to unlock it.

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.

Move the slide switch on the side of the card.

If you take the card out of the camera, there's usually a tiny little switch on the card itself.  You can lock the card so you don't accidentally write over important photos.  Because it's so tiny, it's easy to switch it accidentally...and some are loose so they switch over on their own.

It should have a little switch on the side. You slide it down to lock, up to unlock.

Move the slide switch on the side of the card.

Memory cards have a sliding lock on the side edge...make sure the micro switch is in unlocked positiion.

There is a switch on the SD memory card, slide the switch to unlock position before you insert the card into your camera.

Take the card out - on the side there is a little white slider with a locked & unlocked padlock symbol - move it to the opposite position it is in now.
