Because of a little dispute, the security captain threatened to pay the property fee, and now the door lock is broken. What should I do?

The security captain has no right to ask you for the property fee, which is beyond their duties. You can explain the situation to the owners' Committee and let the owners' Committee talk to the property company. Of course, you have to report to the owners' Committee how many times the security guards break into houses. His behavior has threatened your life and property. The security guard maintains the property safety of the community owner, but he does the opposite. If there is no owners' committee in your community, you can contact the developers directly and let them negotiate with the property company.
