i am a month past due and the landlord threatened that he was going to lock my place up. Can he do that. lease says that he can terminate the lease due to unpaid rent.
Absolutely not. If you're in breach of your lease, your lease presumably says that your landlord has to use the proper legal procedures to evist you, by serving you with notice, then suing you for unlawful detainer, then getting a judge to issue a possession order.

State laws prevent self help by landlords because of the obvious problems that would go along with self imposed remedies. If your landlord locks up your shop you should immediately hire a local attorney to ask a judge to remedy the problem. That said, an eviction action/unlawful detainer is a pretty quick process. If you haven't already paid your rent you should make arrangements to do so or begin preparing for other options.

No. The landlord can never take matters into his own hands and lock up your property. To do that, he needs to serve you with a proper notice and file (and win) an unlawful detainer lawsuit against you. If the landlord locks you out, call the police.
