                            How to Unlock SD Card without Switch?

Summary: A locked SD card puts it in read-only mode, preventing you from modifying the card’s data. If your SD card is locked and the physical switch is broken, use the Diskpart command or Registry Editor in Windows/ or Disk Utility in Mac to unlock it. If all workarounds fail, your SD card is probably corrupt, and you need to format it forcibly. Read this blog for more details.  

A locked SD card restricts you from accessing photos, videos, and other media files saved on it. It also prevents you from adding new files to the card or deleting or editing existing ones.

To add new files or transfer existing files from the locked SD card, you need to unlock it first by flicking the lock switch.  However, if the lock switch of the card is broken, use the Diskpart command or Windows Registry Editor in Windows to unlock the card. On Mac, you can use the Disk Utility feature for this purpose.
