It depends on the legislation of the country you are in.
Go to the police.
In Illinois, a commercial landlord cannot legally lock out a tenant without following proper legal procedures. Lockouts are generally considered illegal self-help eviction and can lead to legal consequences for the landlord. If a tenant fails to pay rent or violates lease terms, the landlord must initiate formal eviction proceedings in court rather than resorting to lockout. Always consult an attorney for specific legal advice related to individual situations.
Lockout Detroit
It is illegal for a landlord to deny access or prevent access to a tenant without having formally completed a legal eviction process. The tenant should contact local law enforcement for help with accessing their property if they are denied access illegally. If the court agrees with the tenant, it will order a law enforcement officer to help the tenant get back in. If the court decides that the landlord knew (or should have known) that the lockout or other exclusion was unlawful, the court may order the landlord to pay the tenant up to triple damages or $500, whichever is greater, plus reasonable attorney's fees. Minn. Stat. 504.225 (1992)
