hello all, new member with a key problem. i have mashed the bottom button on the only power-doorlock key i have for my S4. i thought i might be able to replace the case only and ordered one from a seller on ebay. however, when i opened up my key to get to the green board i realized i dont have a tool for what appears to be the 2 fasteners on opposite corners. they are brass-looking and conical shaped with no grooves or anything for a tool to grab on. anyone know how i can get that thing out of there, or if it isnt possible and i need to buy a new key from a dealer?
