can a commercial landlord lock you out and keep my belongings which are actually customer belongings being sold in my store?

i own a consignment store and i have had a few mwdical issues and have been closed alot in august. my landlord refused to deposit my rent check and sent his manager to have me write another check in the property managers name. the bank would not cash the check so now the landlord put a lock on my store door and is holding everything in the stoe hostage, however, nothing in the store is mine. everything is owned by customers. he has not filed eviction. can he lock me out?
