The manufacturing principle of this lock was originally like this. Although it is rarely used now, it is still informative~

為什麼左上角的水印是相反的？

I still need this lock in my small garden

There is a problem I have been thinking about it for a long time, why the lockers from the same production equipment can have different keys

批量生產那麽多鎖，怎麼做到不同鑰匙開不同的鎖？

[@even1007]

每一批次都是相同的鎖芯，只是在銷售地區會混發不同批次的產品。

5分20秒开始，展示了机器自动识别钥匙并且放入对应的弹子。留意之后所有的工序锁和钥匙都是一一对应的
