You have to push it in until it clicks and then it will lock. To remove it you push in again and it will unlock.
Make sure it's inserted the right way. I had that problem with the Sim card.
Can your phone read/write to the card?

Yes it can read and write to the card just fine. And it is being put in the right way. It just simply won't lock in place for whatever reason. Guess I will see if this warrants a replacement or not.
