Sounds like an illegal eviction. You need an attorney, not a message board.

In Florida, no landlord can change locks to evict a tenant without completing the eviction process through the court system. From your posting, the landlord has now given notice, but that is not enough to bar you from the property/location. You should consult with an attorney and seek legal actions against the landlord.
By retaining your personal property, the landlord has converted it which means that the landlord now owes you the value of the property on the date of conversion.
