It takes a quarter. Turns and drops. Works. The top key works but seems stuck but I didn’t try hard. I didn’t want to break anything. Probably just needs a little WD-40 sprayed in it. The bottom key turns the lock and comes out. Has a small crack in back where something is missing. See pics. Zoom in on pictures for condition. Have a question or need more pictures…. please ask. I give feedback when I get feedback so I know you received it. All sales as is & final! Thanks for looking! Have a very blessed day!
