Hi...
One possible method...
You can remove the locking clip while it is standing up with the card in it. I was able to do this on one phone when I had the same issue. I was then able to take my magnifiers and determine what was going on. (Old men have bad eye sight)
The locking clip can be removed without damaging it if your careful...
Or are you having issues unlocking the locking clip?
