You can also hack lab and bunker entrances. Examine the card reader with an electrohack if you don’t have the ID card.
Warning, though. Depending on where you’re standing, the doors will open and there will be a turret waiting to shoot you to death. Normal turrets in labs, milspecs in bunkers.
On the other hand, the doors in the bunker basements do not have active turrets waiting, so hack them knowing the only risk is that the console will break which prevents you from using an ID card on that door.
