Accidentally switched my sandisk memory to 'lock'

u can unlock your 4gb memory card.
1. Inseart the memory card into a software phone (eg. Nokia 5233, 5230, 5200, 6120c etc)
2. Select the setting > data manager > then format the memory card..
Note: all dates in the card will be deleted.
Use a 4gb supportable software phone.
Try it.. Its really working..

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.

You can't, that's the whole idea with locking it. Just try as many passwords as you can.

Hi, i have here a photo that will show you on how to remove write protect on a micro SD.
1. You need to insert your micro SD into an adapter. 2. Unlock the micro SD through your adapter as shown below. 3. Once done, your micro SD is no longer write protected.

NOTE: The lock switch doesn't lock the micro SD into the adapter; The lock switch doesn't lock the data on the micro SD; The lock switch simply tells the "user" not to write. It just says "please, don't write me."
I hope this helps.

There is usually a switch on the side of the card that will allow you to unlock it. Slide the switch to the other position.

Good luck!

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.

Have you noticed the slider on the side of the card? This acts as a lock and might have been accidentally moved to the locked position, in which case you could just move it back to unlock again. Hope this helps.

What exactly do you mean with lock?

Have you to tried to switch this lock?

Have you tried to format it with the camera? It may need formatting in order to unlock it.

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.
