Remember! Only one key can be held in a lock cylinder.

Anonymous users2024-01-22Not necessarily the door is broken! There is a small pimple on the inside of the security door, and if you twist it, the key on the outside will not be opened. The book of the world tells it that it is the last pass.
But when you close the door, the auto-retractable keycard closes. We reported this kind of accident in the news in Shenyang a few days ago, and later it was the firefighters who helped pry the door open. I guess you accidentally bumped into that little pimple when you were looking at the house in the past.
The anti-theft door key is not easy to insert can be like this: 1, drop some vegetable oil or spray some pencil powder on the keyhole, 2, use a short saw blade to gently pour the edge of the key to make the key smoother. If it doesn't work, you have to adjust the lock cylinder.
Go to the administrator fingerprint and reset it.
Make sure the key opened the door, and don't mistake the key - if not, you're incredible!
Because there is a key inside the door, the outside key is not inserted to the end, and it is not in place, so you can't open the door, you can insert the outside key into it with a little force, and see if you can push the key inside out a little, some locks can be like this.
You ask the property to do you a favor, open it for you from the outside, buy a pack of cigarettes for him, and you can solve it. If you call the lock, at least 1OO yuan, people may not go.
