Cant delete write protection HELP?

So,I bought a sandisk memory card for my phone to save mp3s on well,everytime i try to save it says this device has write protection.Then when I try to format it I can’t format it because of the write protection.What do I do?

Hi. Grabbed this from their KB site. Hope this helps.

SOLUTION 1 - Unlock the memory card.
SOLUTION 2 - Toggle the lock switch.
SOLUTION 3 - Try to Format the card using Disk Manager (For all memory cards)

Does the KB site tell HOW to do Solution 1?
