How can the badminton court be locked when it's right inside the apartment complex?? Who is using it?

Shouldn't we consider the convenience of residents regarding the badminton court door lock?

Recently, I visited the badminton court in the neighboring complex, but I couldn't use it because the door was firmly locked. When I asked a friend, they told me that it is almost always locked, making it difficult for residents to use freely. Exercise facilities are spaces provided for residents' health and community life, but restricting access like this defeats their original purpose. Of course, certain rules are necessary for management and safety, but a system where residents must obtain permission to exercise is excessively inconvenient. At the very least, there should be clear guidance regarding usage hours and reservation methods, and I believe a system should be established that allows anyone easy access. Since facilities within an apartment complex are shared assets for everyone, not the exclusive property of specific individuals, shouldn't the management listen to residents' opinions and keep them open whenever possible? It seems desirable to allow anyone to come and exercise...
