hawke sidewinder 30 SF flip up covers Help Please!

Asking this question, after searching the net and this forum, makes look really dumb. Received a NIB Hawke Sidewinder 30 SF from UPS. Opened it up and read the instruction book and wanted to look through and see the reticle. I can't get the flip up covers up. I have 2 rifles with flip up covers and I thought I knew how to operate them but apparently not. Also included were some round pieces of plastic that I think they are calling 'keys'. I have no idea what they are for. Everything else about the scope works just like the others I have. Kind of useless if you can't get the covers open. LOL
