The new house has been moved in. Why does the property still have the owner's key?

The new house has been moved in, and the property should not leave the owner's key.

Before the house moves in, in order to prevent some accidents, the property management company can keep a key after obtaining the consent of the owner in case of emergency.

After the owner moves in, the factors of emergency disposal no longer exist, and the property management company should return the keys to the owner in time.

If the property company seizes the owner's key privately, or even enters the owner's home privately with the seized key, it is suspected of infringement, and the owner can claim rights from the property company.
