You should be able to easily press the buttons (by using them with E) next to the gate to open it by entering the correct code.
Can you press the number buttons?
Also use E when trying to enter the floating contraption. That can be a bit more tricky, (don't remember why but I could not make it work in every case/position. Something with entering/activating that pod.) but a few presses around the button should get you in.
