How do I fix a “Memory card locked” error on a Canon PowerShot?
Answer
A “memory card locked” message on a Canon PowerShot usually means the SD card’s physical write-protect switch is set to Lock, or the card needs to be reseated. Slide the switch toward unlocked, reinsert the card firmly, and test with another card if the error remains.
Before you start: stop right away if…
- Formatting an SD card erases the photos on it; copy needed images to a computer first.
Follow these steps
Power off and remove the SD card
Turn the Canon PowerShot completely off, open the card door, and remove the SD card carefully without bending it.
You should see: The memory card is out of the camera and can be inspected.
Unlock the write-protect switch
On the SD card’s side, find the small Lock switch. Slide it fully toward the unlocked / write position (usually away from the “Lock” label), then reinsert the card until it clicks and close the door.
You should see: The PowerShot no longer shows “memory card locked” and can take a test photo.
Reseat or try a different card
If the error remains, remove and reinsert the same card once more. Then test a different unlocked SD card in the PowerShot to see whether the message follows the original card.
You should see: Another card works (original card/switch problem), or every card fails (camera slot/support path).
Format only after photos are safe
If an unlocked card still misbehaves but important images are already copied off, use the camera’s format option for that card. Skip formatting if you still need data recovery from the card.
You should see: A freshly formatted unlocked card records photos normally, or the error persists for service/support.

Extra tips
What to look for: The exact “memory card locked” message on the PowerShot screen, and the Lock / write-protect switch position on the SD card edge.
Before you change anything: Power the camera off before removing the memory card. Check the SD card’s side switch before formatting or discarding the card. If the card has important photos, copy them to a computer before formatting. Avoid forcing the card slot if the card does not seat smoothly.
