My SanDisk will not unlock

Look closely at the memory card itself. There should be a tiny picture of a lock indicator on the card and a little tab to click or move to the lock position. There should also be a picture of an unlocked lock to signify which direction you need to move that little tab in order to unlock the memory card. Try sliding it to the unlock position to solve your issue.

Try the locking mechanism on the side. It can lock sometimes if it is loose,as you put it into the slot. If necessary tape it in unlocked mode. It (the switch) will appear on the upper left hand corner of the SD card or micro SD adapter.

On your SD Card, there is a Lock switch. Turn the Lock off to unlock the memory card.

Without knowing what the specific error is this is my best guess:

SOLUTION 1 - Unlock the memory card.
There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked.

SOLUTION 2 - Toggle the lock switch.
If the lock switch is not on lock:
1. Slide the switch up and down. Repeat this 3 times.
2. Let it stay on the Lock position for 30 seconds.
3. Slide the switch up to unlock the card.
4. Try to transfer files into the device.

I use a Nikon D300 and have Sandisk Compact Flash memory cards. i ahve not come across this problem but would suggest that you insert the memory card into your camera and reformat the memory card. This should clear any errors in the system BUT IT WILL ALSO WIPE ANY PHOTOGRAPHS YOU AHVE TAKEN when formating the memory card.

I guess it is a simple switch problem..

try to switching it between lock and unlock many times until it become ok again..

If it will still not unlock itself, try to format it, for some errors to erased and starts a new one.

hi
the unlocking is due to digital camera and not due to card. card do not have any locking feature. checkup on camera password

or alternately ask replacement fm company as this as 5 yrs warranty
