Memory card is universally used to expand the storage capacity of an Android phone, digital camera, or handheld game console. But sometimes you cannot place files to the card as normal, it's locked. 

When is a memory card locked? In general, there are two situations:

1. The memory card's lock switch is on, and it's write-protected.
2. You set a password to lock the memory card but forget the password.

What's Memory Card Unlocker

Memory card unlocker sounds like an app on a phone or a program on a computer, such as SD card car master.exe or memory password unlocker.apk. The unlocker is advertised to encrypt a storage drive and manage the passwords, to ensure a high level of security. It's more like a password manager than a password unlocker, and most ask for a considerable amount of money to use.

Even some online memory card unlocker software is able to unlock a password, remove read/write protection, it's expensive. If your (micro) SD card is locked, due to the write protection or forgetting the password, try to clear the lock like what we taught here. Never attempt to find memory card password remover software license code from unknown sources, it's illegal yet riskful. Particularly, it ruins data on the card.

How to Unlock Memory Card

Next, you're supposed to check your memory card switch. Normally, SD card, SDHC/SDXC card, Eye-Fi card, and other types of cards have a small plastic slider on either edge, which is used to "lock" or "write-protected" the card. Once the lock switch is on, manners of deleting, copying, transferring, or saving files are forbidden. You should take an easy step at first, to check the lock switch is on or off.

Method 1. Toggle the lock switch

As the example of my 32GB Sony SD card shows, it has a yellow switch on the left edge, and it's movable. Make sure that the lock switch is slid up (unlock position).

If the lock switch is loose and moves easily between the lock and unlock position, it's likely corrupted. You will need to replace the memory card with a new one.

Method 2. Remove write protection

Reasons for why a memory card gets locked would be easier to figure out if your phone or camera sends a warning, saying the disk is write protected. This problem is almost settled down. You need to perform the attrib cmd on a computer. Insert your infected memory card in a card reader and connect it to the computer. Follow the steps to open the elevated command prompt and clear the protection.

Step 1: Press Windows + X keys, Choose Command Prompt (Admin).

Step 2: Type these commands one by one and press Enter key after each:

  • diskpart
  • list disk
  • select disk # (# is the number of the SD card)
  • attributes disk clear readonly

Method 3. Force erase SD card without using a password

The most recommended way online to unlock a memory card is by installing ES File Explorer on your Android. But this app has been removed from Play Store because of policy violations.

Forgetting the secret word, number, or pin of the memory card takes a lot of work to restore. The last resort to decrypt a password-protected card is to send it to the vendor, perhaps they have a universal key to break open it.

How to Recover Erasing Data from Memory Card

Force unlocking the SD card would be likely to erase data, perhaps you have tons of precious memory photos, video recordings, or documents there. Is there any way to regain the loss? Yes, by applying a third-party SD card recovery freeware.
