Take out the memory card look on the left hand side of it and it might say in little letters lock and there's a little thing that moves up and down and then move it up.

How to troubleshoot problems?


I went to school, to learn how to trouble shoot electronic equipment. Took me a few years in school and after that a few years to improve my skills.
Not knowing what camera (and nobody to ask) I will try to give some hints.
The message, means the logic in the camera can't "see" the memory card. Reason? perhaps it was put in the wrong way around? perhaps it is defect.
Defects: one or more bent contacts. A bent contact pin in the camera when it is a CF card. Some dirt or oxidation in the camera, making it impossible for the camera to read the card. Just a scrap of paper, 1 mm of size can block a contact.
Only is rare occasions, the defect is in the camera itself. And then you can't solve the problem.
When you have a SD (SD, SDHC or SDXC) card, the lock switch in the lock position, should give the message card locked. When the card is not formatted the camera should give the message no format, so you don't need to look in that direction.

Canon SD1300 memory card locked


There are several possible causes for "memory card locked", "memory card error", or "no memory card". The most common cause is having the tiny slide switch on the side of the card in the wrong position. But, if you've checked the slide switch, the internal switch in the card slot may be jammed by a grain of sand or gunk. Here are troubleshooting steps for this problem. Recommend the toothpick fix for your particular problem.

My digital camera says card write protected. changes many memory cards still the camera says card protected i slide the switch of the mmc up and down the screen still says card protected and i can't take...


Hello ranmer 9960:
First lets try the card in your PC to make sure the card is working. If it is working in the PC then its probable that the camera is not reading the lock switch correctly. Lets try setting the protection lock switch on the card in between the locked and unlocked position. If that doesn't work then we can try putting some electrical tape (because its thicker than cellophane tape) over the lock switch on the card This may help your cameras lock switch reader function correctly. Make the piece of tape wide enough to cover the lock switch on the card but don't cover the copper contacts.
Try these suggestions and if it works then give the thumbs up a click.
If not we can try something else.

Inserted new memory card and getting error message - saying it's locked but it isn't. tried 3 new cards all with same message. Tried to format but the option to do so isn't accessable


Hello

If the card works in another camera or another card doesn't work in your camera , the problem is with your card reader in your camera.

If you open you sd slot and look inside with a sharp light , you should be able to see on the left side of the slot there is a little copper or spring steel lever switch. This switch work as follows:

1. When no card is inserted / no write protection , the switch is open and thus the protection is off.
2. When locked card is inserted , the tab is depressed and tells the camera that the card is lock.

Contrary to popular belief ,the little tab on the sd card is not an electronic switch and does not physically influence the card operation itself. If you put a locked card into a camera without a sd lock switch , you would still be able to use the card normally.

It is incredible difficult to fix this switch because of space limitations in the sd card. Look into the sd slot and if you can see the switch , use a needle to pull the little tab down toward the base of the camera by about 2mm or until it works being careful not to bend it.

If this does not resolve your problem , there might be a short in the switch circuit and the camera will need to be disassembled to resolve this error. This should cost no more than $50.

Please feel free to contact me if you need further information

Kind regards

"Card Locked"


Hi!
There's a small switch on the memory card reader inside the camera which detects that the card is locked. Most likely this switch is broken. You can try to point it with needle or something but I'm afraid you will have to give it away for a repair to a local repair shop or Canon service center.

My camera keeps saying card locked and its not locked and i have tried other SD CARDS and its saying the same thing! please help?


Okey, this can be tricky, but it worked for me.

I have Canon Ixus 60 and Kingston SD 1gb memory card.
After loading set of images on my laptop and putting the card back in to camera, screen displayed "Card Locked!" message.

I did everything to check the common flaws, but still the same message occured.

Material needed:
1 paper clip

The socket for memory card has this tiny detector for sensoring if the card is locked or not (same side as the lock switch on the MC). For some reason it was sticking out from the side. So, little fiddling with paper clip to put the detector back in and another try to put the camera on, everything worked out just fine.

There is a tiny button on the side of the card - so small you can hardly see it. Just slide it up and voila All is solved.

Locked Card


Take the memory card out of the camera. Look at it carefully and you will seea small tab. Move the tab from the locked position to the unlocked position. Re-install the memory card into the camera and then you're done.
