Is it possible for a management office to block access to both car park and the residential unit?

A friend of mine has not paid many months of his management/maintenance fees and lately the Management Office has blocked him from parking his car as his designated car park (very common practice)

Apart from this, he is also unable to access the floor which his unit is located.

Kalau block resident gi carpark, we can understand. But how can you block the lift access to his unit?
Tak payah balik rumah la?

Bole ke buat cam gini? He plans to make a police report.
