Why should the property keep the house key?

This question is really a good one. First of all, the property management company will not force you to leave the decoration key, but it will save you a lot of money. For example, upstairs decoration needs to go to your house to see waterproofing. In that case, are you going or not? Will the property management inform you to go once? If you use your regular key to turn in the keyhole when you check in, the decoration key will be invalid. Even if the property is available, you can still enter your home. Don't worry about giving the key to the decorator. What are you afraid of if the property company can't run away?
