Do you have to pay move out fee if your lease says $0 move out fee?

Rent a small lot to set my mobile home, it is a trailer park. I own it. I have sold it n informed my landlord I will be moving. My lease says $0 move out fee but he told me I have to pay $200 move out fee in cash not a check or he will lock the front gate An the trailer won't go anywhere until it's paid. I've read over my lease it says $0 move out fee am I obligated to pay this?
