Having one key is about the only advantage. The barrel locks are so weak they can be opened as quick with a screwdriver as s key. My basement was broken into several years ago. Someone simply slipped a screwdriver or similar under the edge of the door, pried, and bent the tabs on the barrel locks. Barely even a noticeable mark on the door. I just pressed on the tab with my thumb and it bent back in place.
