I took my SD card out of my camera to allow someone else to use it. Now when I put it back in it reads-card locked-why?

There are two possibilities that I can think of. 1) The SD card is full. You will need to copy the pictures off the SD card and onto your computer, then format the card. You can probably do this in the camera, but MAKE SURE you have copied the pictures you want to your computer because the format will erase everything. 2) The SD card is write protected. Look closely at the SD card there is a little slide switch that "locks" the SD card so that your camera cannot put any pictures on it. This slide switch must be in the unlocked position (or NOT locked).
Hope this helps.

This is usually caused by the SD card, and is rarely to do with the camera. On the SD card there is a small slider - which allows you to lock the card (to prevent accidental erasure).

If you put in on the table with contacts upwards, corner cut top left, then the slider is on the right hand edge, about 1/3 the way down. If it is slid to the top position (nearest the contacts) the card is unlocked. If it is slid down (away from the contacts) the card is locked.

If it is a damaged / "cheap" card, sometimes the slider falls out, in which case the card is locked. You can still read from it, but not write to it until fixed or replaced.

First check is to turn the camera off, remove the card, move the slider to locked, then back to unlocked. Replace in the camera and turn on.

Have you tried the camera with another SD card, to see if the problem persists? (A reputable photo store will often lend you a card for the 20 seconds it takes to do this test)

All SD cards should have a toggle, unless it has fallen out, or its one of the "specials" usually found in Sat-Navs which were made to be read only (with maps on). You don't say which Fuji you have - some used to take xD cards, which don't have a slider, but are easily recognisable by their one curved side of the card. I'll assume you have an SD card for this reply.

Here's a recap of what you are looking for:

On the SD card there is a small slider - which allows you to lock the card (to prevent accidental erasure).

If you put in on the table with contacts upwards, corner cut top left, then the slider is on the right hand edge, about 1/3 the way down. If it is slid to the top position (nearest the contacts) the card is unlocked. If it is slid down (away from the contacts) the card is locked.

If it is a damaged / "cheap" card, sometimes the slider falls out, in which case the card is locked. You can still read from it, but not write to it until fixed or replaced.

First check is to turn the camera off, remove the card, move the slider to locked, then back to unlocked. Replace in the camera and turn on.

As to your choices if it is broken (or a read only map SD card), then you might like to try the camera with another SD card, to see if the problem persists? (A reputable photo store will often lend you a card for the 20 seconds it takes to do this test)

Repair is very fidgety (even assuming you can find the slider). Most people tend to migrate their stuff to a new card.

Check to make sure you didn't accidentally move the locking switch on the SD card to the locked position. There will be a switch on the side of the card. One side of the switch says locked, (or has picture of a locked lock) and the other side says unlocked, or has a picture of an unlocked lock. Try it out.

I had the same problem. i dont know if this will work for yours, but what i did was when i had the card in the slot i pushed in it as far as i could with my finger nail and then it clicked right in.

I have the same camera and the same problem. Can't use SD cards anymore, only the obsolete Multimedia Cards that are extremedly hard to find on shops because SD cards are the substitute for them... hope you can find a Multimedia Card. At least mine works fine with them.

you have to use the origanal samsung chip try samsung.com
