Can a landlord of a commercial property change the locks if i as a tenant have a lease agreement?

A landlord generally cannot change the locks on a commercial property without prior notice or without following the terms outlined in the lease agreement. Most leases specify the procedures for access and lock changes. If the landlord changes the locks without proper justification, it may violate your rights as a tenant, and you could potentially take legal action. It's important to review your lease and consult legal advice if this situation arises.
