The Bonk can be picked up by reaching for it and pressing the trigger button on your controller. There are two handles you can use to pick up the Bonk: on the front and on the back. You should now grab the second handle with your other hand. With holding the Bonk in both hands, you can go up to a door and breach it.
You can use the Bonk to open a door regardless of whether it is open or not, but it is of course usually utilized to open a locked door. When you are standing next to a door, you can slam the Bonk against the door, which will also make a distinctive sound. It usually takes more than one hit to open a locked door. The number of times that you need to slam against tthe door is measured by how hard you hit it.
