Does the owner have the key to my house?

If it is a new house in your hometown, after you get the key to your residence, it will be divided into six official keys and two construction keys. The construction key is used by you to decorate the construction personnel and to maintain the house in the early stage of the property. If you lock it with an official key, the construction key will never open your door again, and it will automatically become invalid. So it depends on what kind of key you put in the property and whether there is a regular key to open me.
