SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.

How do I unlock the write protect on my camera? There is no deselect option.

The lock is not in the camera, it is on the SD memory card. The lock "switch" should be in the up position, so the camera can feel it is off. If there is no notch on the memory card or it is in the lock position, your camera will scream UNLOCK.
Please remove the card and check the notch is there and it is in the up position, like in the picture down here:


The notch is to the let of the arrow above the word lock.
No notch is the same as locked. If the memory card is o.k., and the camera is still telling it is locked, perhaps someone ever tried to put in the memory card the wrong way around, and the internal switch is now not working. It that is what happened, I'm afraid you can't solve the problem. ou need a tech guy to solve that.

Need help working my camcorder/camera

In order to record, the camera needs to have a memory card installed. This particular camera needs an SD format card. If the camera does not have a card installed, the card is not properly formatted, or the card is full, you will not be able to record. Also, these cards have a write protect lock tab. Make sure that the tab is not in the lock position. The card should be formatted FAT32. If you can read the card on your computer, make sure it is not full and that the card is formatted FAT32. If you have another camcorder or camera that uses SD cards, you might want to try formatting the card, just to be sure.

Put memort card in camera,,didn't realize I had to format disc.followed instructions in book to format but does not tell me it is formatting,,, still get unsupported card message

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. The second most common is trying to use a 4GB or higher SDHC card with an older camera made before SDHC format came out. Please note that your particular model camera can only use up to 2GB standard SD cards. These are relatively inexpensive these days, and may be purchased on Amazon if your local store no longer carries them. There are also other common causes if the above didn't help, with troubleshooting steps for this problem listed here.

EVERYTIME I put a sd card in it says it is full? I cant find my manual and have no idea if I have the menu on the right settings? Can you help me asap... Thank you.

I don't know exactly what the problem is, but it could be related to the card. Does it have a little switch to lock the card? The camera might be telling you it can't write to the card because it's locked.
If that doesn't fix it, here's a link to the camera's manual. Formatting the card should clear all the photos.
I hope this helps! Please rate this solution if it does!!

Message card is locked

Usually, the write protection is on the memory card itself.
You should power off the camera, take out the memory card and move the little switch on it's side to disable the write protection.

Good luck,

Memory Card Locked The card works fine in my other Canon Camera, but not in my A620. I've switched out the cards and nothing works in my A620, but they all work in my other Canon. Memory Card Locked is...

I'm assuming the slide switch on the side of the card is in the correct position. In order for a card to work in a particular camera, it must first be formatted in that camera. This completely erases it so download any pictures still on it to your computer first.

Camera says Card Locked and I can't Reformat the Memory Card

From the problem described by you, it seem your camera has gone into a internal memory error and hung. Try to take out the battery, the memory card etc , clean and then reinsert and then power on? Try this it might work.... Generally the camera should start working normally once you will take out the battery, since it will reset.
If it still does not work, then think you might need to take it to Canon. They are very helpful and could sort out if you have system software problem. But Before that, I suggest that you must take out its memory stick, the battery etc and keep the camera like that for about 15 minutes. Then only reinsert the battery (fully Charged) and then try to reformat the memory card. If you are lucky, you might not need to go to Canon. Best of Luck.

Memory card blocked!!

I have the same exact problem with my camera and NOTHING works. Bought a new card, didn't work. Checked and rechecked the card to make sure it isn't locked...didn't work. I have no solution for you but to tell you you are not alone with this problem and it isn't your card or the little slider on your card. It is within the camera.

Memory Card Locked

Do you have a computer that will read the "memoery cards"? Try reading the cards. If there is nothing on the card you still should get a message telling you the status. Check the setup of the camera. Some cameras allow you to lock the memory card from setup memu. You might also need to "format" the card before you use them.
