How to complain about the unreasonable charges if the owner of the property car is required to pay the 200 yuan deposit when it enters the new equipment?

What you said is the deposit, which can be refunded. I don't know what charges you're talking about. It is normal for owners to enter the community to collect vehicle management fees. According to the general property fee, it should be from 60 yuan to 80 yuan, and each area is different. There are usually local price approval guidelines.
