Feed Man I got it from a Canadian dealer. Seems odd that the cam would click lock and click eject for a few days . I was playing with that SD card today works fine in my digital cam (locking and unlocking . So I tried a second sd card in the trail cam. That one works in the trail cam click in click out . All the other sd cards I tried work also. I have compared the two cards but can see know differences in them. Will haveeto see if it will stop working on a second card.
