Unlock card My camera is locked and I am trying to "unprotect" my camera so that I can take pictures. I press the blue arrow and key button, but everytime I choose the unprotect function, it says card locked. Please help. Thank you.

The protect function allows a user to protect a picture from accidental deletion. To unprotect a picture on your camera, scroll to the protected picture that you want to delete, then press the Menu button (the button to the right of the Play button.) Scroll down the menu and you should come to an option that allows you to Protect/Unprotect the picture. Since your picture is currently protected, deselect that option. You should then be able to delete the picture normally.

Alternatively, you could also format the memory card, however this deletes ALL photos and data you have on the memory card. If you are trying to completely clear the memory, this is the best way. After turning on your camera, simply press the Menu button, scroll to Setup, then scroll down to Format. Select Format, it will ask you if you want to format the memory card, or the camera's built-in memory. Format whichever one you want to clear, if you are using a memory card then your pictures are stored on the memory card. It will take a few seconds to format.

Hope this helps.

While viewing the particular locked photo, press the Menu button and select Lock/Unlock to toggle. Your camera's menu might also call it Protect/Unprotect. Hope this helps!

It's not the camera, it's the 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. If the switch is already in the proper position, slide it fully the other way and then back again.

Press MENU to enter the menu. Select the SETUP menu (the wrench icon). Select Protect (the key icon). Protected pictures are indicated by a little key icon in the upper-left corner of the picture. Navigate to the protected ones and press up/down to unprotect.

Or is the entire card protected? 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.

Warning: Do not enter any wrong unlock unlock codes on your Sony Ericsson K800 mobile phones. If you enter over a certain amount of wrong unlock codes on your mobile phone, your phone may get hard locked and sometimes become unusable.

If your Sony Ericsson K800 mobile phone does not have a left arrow button/key(e.g. Sony Ericsson W950i) and on a few phones(not all) that have a "JOGDIAL" you must press the "down arrow" key/button instead of the "left arrow" key/button for step 2 & 4. We mean by "Down Arrow" to direct the Jogdial down! In the Sony Ericsson W950i and some other models, the down arrow button/key would be located on the side of the phone.

Go to the playback menu and select it (you may have to adjust the circular option know to get to the playback menu). Once there, scroll to the picture(s) that are locked by using the sideways selection arrow buttons. Then select the up or down arrows, which will lock or unlock your picture. You can also erase any locked pictures, in case you want to, by formatting the xD card. Hope this helps.
