Can I call the police without paying the property fee or giving the key?

Generally speaking, in most areas, failure to pay property fees may lead to a series of consequences, including being restricted from using certain services or facilities, or being forced to charge fees by legal or administrative means. As for the feasibility of calling the police, it depends on the local legal system and legal requirements, so I suggest you directly consult the relevant law enforcement departments or legal professionals to understand the specific regulations applicable to your area. Please note that the above answers are only general suggestions and do not constitute legal opinions in any way. If necessary, please consult local legal professionals for accurate legal advice.
