If you are on my site you are probably an avid hunter like myself and I expect you are taking advantage of the use of a trail camera for monitoring game movement, etc.
I have amassed a collection of (8) trail camera that I am currently using. They are especially useful when it comes to turkey hunting, particularly the time lapse units that do not rely on motion to trigger the camera. You can watch a large portion of a field, road, pasture, etc. and get a good idea of when and where the birds are coming and going.
Of course you are going to need SD memory cards for the camera to record the photos too. I like to have at least (2) cards for each camera so I can pull one and install a fresh one all at the same time with no down time for the camera.
With all those cards I occasionally run into a problem with one. Recently I had the lock fall out of one of my Sandisk Extreme cards. When this happens you cannot write to the card or erase any of the photos from it.
The card on the left has it’s lock in place and the card on the right is missing its lock!
An easy repair for this is to cut about a 3/8″ wide section of scotch tape and wrap it over the lock area being careful not to cover the copper contacts on the back of the card.
I pulled this strip of tape off using the cutter on a tape dispenser but I would recommend you cut it with scissors for a clean edge that is less likely to snag in the card slot.
Install the tape from the back side so as not to cover the contacts and wrap it tightly over to the opposite side.
The camera of computer will now read and write to the card normally.
You could also fill the lock slot with a stiff epoxy or superglue a strip of plastic in place to simulate the lock for a more permanent repair.
