Archaeology warehouse door locked

It won't open for me and my friend for the co-op mission. The first time it was locked and we sat there for like 10 minutes and it eventually was just randomly unlocked when we maximized the game again. One of us had to go before we could finish the mission and now the door wont open at all. All the videos of it just have people walk up to it and back away and it opens, and trust me, we tried a lot of things now. It isn't opening. Here's a picture of the door I'm talking about http://i.imgur.com/KhHyYaF.jpg
