The key of the post was broken, I used it to exchange for a new one.

The key was simply thinking that if you go to the home center to buy it, you can buy it immediately. However, this dial lock was troubled because it was not in any home center, and it was helped by Mr. Monotarou on the net, and it was already a deep emotional tear when the product was acquired. Thank you.
