Question about running amber at fort aspenwood

I've recently started playing the Kurzik side of Fort Aspenwood and I'm confused about running amber through the gates. For example, right at the beginning a group of us zone and capture the purple amber mine and we all get some amber. I'm trailing along behind the lead guy and when he gets to the gate it opens for him and we all go in. However, another time I zone by myself and get the amber, but when I reach the gate it is closed and I have no idea how to open it. What am I missing? I'm sure I looked like a complete tard running around in circles trying to figure out just how in the heck I get back into the fort.

There Should be a lever or teleporter...

there are levers by every gate called "Gate locks" hitting one will open it, then theres one on the other side to close it.

Thanks for the help. I should've known it would be something as simple as that.

If you hold down Alt you can see all allies as well as labeled objects. You can use Alt to help you click on a Gate Lock from a distance (Click on the name).

Also, Ctrl allows you to see enemies. I figured I should mention that, since it's basically the opposite of Alt.
