When I went out to play with friends last week, I tried to take pictures with my Canon camera, but I kept seeing the warning “The card’s write protection switch is set to lock” on the camera screen.
After several unsuccessful attempts, I finally managed to solve the problem. I handled it like this…
1: Check the write-protect switch of the memory card
Usually whenever you see “The write-protect switch of the card is set to lock”Indicates that the memory card in use is in the locked (down) position. This makes it impossible to capture new images or even delete existing images.
To solve this problem, you just need to flip the “Write protect switch“Unlock upwards on the memory card.
It’s that simple, you should be able to capture a new image again with the camera.
You may see “The write-protect switch of the card is set to lock“The error message on the camera screen is due to poor contact between the camera and the memory card. Simply put, the camera cannot read the memory card.
Another possible cause of the alarm is that the metal contacts of the memory card may have been oxidized over time, resulting in poor contact with the camera.
To solve this problem, just wipe the metal contacts of the memory card with white vinegar or alcohol. Remember to wipe the metal contacts of the camera memory card slot with an eraser.
3: Check the camera’s memory card slot sensor
Sometimes the camera lock/unlock switch will get stuck in the locked position. The cause of this situation may be blocked, dirty or damaged switches. Nonetheless, you will see a “card’s write protection switch is set to lock” alert on the camera screen. You can solve this problem by gently pushing the switch to reset it back to the unlocked position.
You can do this with a toothpick or any other non-metallic object that can fit into the memory card slot. Try to reinsert the memory card to check if the problem is resolved. However, if the false alarm is caused by damage to the camera sensor (lock/unlock switch), you may need to visit the nearest Canon store or send it to them for repair.
4: Use scotch tape
After trying all the above methods, do you still see the “Card’s write protection switch is set to lock” alert on the camera’s LCD screen? Then it is likely that the “write-protect switch” of the card is broken or loose, and it is easy to slide to the locked position when installed in the camera.
That being the case, maybe use scotch tape or scotch tape to fix it quickly. Here is how to do it:
- Cut and trim a small piece of scotch tape, then stick it to the slot where the lock switch is located. Make sure that the tape is small enough to only fix the switch in place, otherwise you may end up getting stuck in the camera.
- After the scotch tape is in place, it’s time to try to slide the card back into the camera to see if the problem is resolved.
5: Replace with a new defective memory card
If none of the above methods fix the error, the memory card may be damaged. In this case, the only logical solution is to replace the defective memory card with a new one.
6: Reset camera settings
If you try to use all of the above methods to solve the problem without success, then the problem may be with the camera’s firmware, not with the card reader itself. If this is the case, then you may need to update the camera’s firmware to solve the problem.
Here is how to reset settings for different types of cameras:

step 1: Find the camera Reboot Button
Step 2: After finding the reset button, according to and catch Stay on it for 3-5 seconds to complete the operation.
Step 3: Try to use the camera again to see if the problem is resolved.
