Does court property need to be present to unlock the auction house?

This situation can be solved by itself.

The house is unlocked, so you can change the lock yourself. Inform the court and the original landlord before changing the lock (if you call, it is recommended to leave a message, WeChat or SMS) and inform the property to be present.

If the law stipulates that the house needs to be auctioned, the original owner has no right to control the house, which is enforced by the court, so it should be operated reasonably.
