SD Cards are great resources for storing information and data. These cards are compact, lightweight, relatively inexpensive, and compatible with various devices. If you happen to want to access the information in your memory card, but you get a message that it is locked, you are probably confused and wondering what to do now?

Do not worry. Unlocking the memory card is easy and simple. This article will talk about what a locked memory card is, why memory cards have such a feature, and how to unlock a locked memory card. So stay with us until the end.

What happens when the memory card is locked?

What exactly do you think locking a memory card does? You should know that the purpose of locking a SD Card or SD card is to protect the information inside it from being written or deleted. When the memory card lock is on, you can only read and view the information inside. Therefore, you can’t make changes to them.

When you have a locked memory card and want to save a file to it, you will see a message indicating that your memory card is locked and you can not add anything to it. This protects the information inside this

memory card from being deleted or rewritten.

How to detect a memory card lock

In most cases, you can easily tell if the memory card is locked or unlocked. There is usually a small lock key on the left side of the memory card to determine if the card is locked or unlocked. If this key is off, the memory card is locked. Dragging it up will unlock the card, and you can enter your information into the memory card.

But this is not always the case. The lock switch may be broken, or you may not be able to access it for any reason, such as a card getting stuck in the device. In such cases, it may be difficult to tell if the memory card is locked or unlocked, but do not worry because you can still figure it out.

For example, if your memory card is in the camera, take a few photos and check if the photos are stored in the memory card. If the photos were saved, your SD Card is open. Otherwise, it is locked.
How to back up files from a locked memory card

Backing up a locked memory card is very easy, and you can do it without even unlocking the SD Card. The lock on the memory card protects the data and information inside the card only against writing and deleting. So there is no problem copying data, and nothing will stop you.

Follow the steps below to back up the files inside the locked memory card:

1- Connect your memory card to your computer using a card reader or memory card slot.

2. Open the memory card and select all the contents you want to back up. Then right-click and select Copy.

3. Go to the place where you want your backup copy to be saved. This location could be somewhere on your computer or an external storage device. Then right-click and select Paste.

Note: If you can not recover some files inside the SD Card in the desired location, or if some files are lost or deleted, you can use the memory card data recovery software to scan and recover files that are not visible.
