Want to know how to fix? Don’t worry, this post will share 3 solutions to unlock the SD card.

Solutions to unlock the SD card

Solution 1: Remove physical write protection from your SD card

Generally speaking, all standard SD cards have a physical lock which can be switched up and down to enable or disable the write protection. Therefore, when you find it unable to write to your memory card on a Windows computer, a Mac, or on the digital camera, you are first suggested to check the lock. Here’s what you can do:

Step 1: Locate the Lock switch on your standard SD card. For mini and micro SD card, you need to insert it into an SD card adapter, and then find the switch on the adapter.
