You are now presented with the Service Tunnel door. This time you can't turn the wheel so you have to actually remove the door from its hinges. Tap the hinges to move the covers and use your wrench to remove all 6 nuts by selecting it from your inventory, tapping it on the nut then rotating the wrench upwards.
Once you have removed all 6 nuts, the door will fall off its hinges and you can proceed through it.
