Missouri Tenant Rights: Changing Locks Legally

Feeling secure in your Missouri rental home is essential, especially if your safety is a concern. Many renters wonder whether they have the right to change locks themselves, what rules apply, and how Missouri law safeguards both tenant security and the landlord's access. Understanding your responsibilities and rights will help you make informed decisions about protecting your home and privacy.

Tenant Rights and Lock Changes in Missouri

In Missouri, there is no specific law directly stating when tenants can or cannot change the locks on their rental unit. Instead, tenant and landlord rights about locks are governed by the broader Missouri Revised Statutes Chapter 441 (Landlord and Tenant) and by your lease agreement¹. This means your specific rights may depend on your rental contract and general landlord-tenant law.

• If your lease is silent on lock changes: Tenants should not change the locks without the landlord's explicit permission, since landlords are legally allowed reasonable access for maintenance or emergencies.
• If your lease prohibits lock changes: You must follow this rule. Violating it may put you in breach of the lease.
• If your safety is at risk (e.g., domestic violence): Missouri has special protections—see below.

If you’re thinking about changing the locks, always communicate with your landlord first and seek written approval. This reduces the risk of conflicts or possible lease violations.

Special Protections for Domestic Violence Survivors

Under Missouri Revised Statutes § 441.233, tenants who are survivors of domestic violence may be entitled to improved security measures, including changing locks. If you provide the landlord with a written request and supporting documentation (like a protection order), your landlord must comply or allow you to take security steps yourself.²

• Request must be in writing and specify the security measure needed.
• If you change the locks, you must provide the landlord with a copy of the new key immediately so the landlord retains lawful access.

What If Locks Are Changed Without Permission?

Changing locks without landlord approval—unless required for safety in domestic violence situations—may be considered a lease violation. Landlords can take action, including serving a notice for lease violation or, in some cases, beginning eviction proceedings. Always check your lease and communicate openly to avoid issues.

Relevant Forms and How to Use Them

• Domestic Violence Protection order (Adult): This is used if you need legal protection and to exercise rights related to lock changes as a survivor. The Missouri Courts provide the Adult Abuse/Stalking Petition for Order of Protection (Form 5.10). You file this form at the circuit court, and a judge may issue an order aiding your request.
  • Example: If you receive an order of protection, you can give a copy and written lock change request to your landlord to trigger your rights under Missouri law.

Your Landlord’s Right of Entry

Missouri law gives landlords some ability to access the rental unit for repairs, emergencies, or inspections. Changing locks without sharing a key violates this right and could have legal consequences. Landlords must respect tenant privacy and provide reasonable notice before entry unless there is an emergency.

How to Legally Change Locks as a Tenant in Missouri

Here’s an overview of safe and legal steps if you believe a lock change is necessary, especially for domestic violence survivors:

• Review your lease for any terms about locks or modifications.
• If your safety is at risk, collect all documentation (such as a court protection order).
• Write a formal request to your landlord describing your need and referencing Missouri Revised Statutes § 441.233 if applicable.
• If changing locks, do so by a qualified professional and provide a new key to your landlord right away.
• Keep records of all communication in case of disputes.

FAQ: Missouri Tenant Lock Change Rights

1. Can I change my apartment locks without telling my landlord?
   No. Unless you’re a domestic violence survivor acting under special protections, you generally need landlord permission and must provide a copy of any new key.
2. What should I do if I feel unsafe in my rental?
   Contact law enforcement if it is urgent, and seek a protection order. Then notify your landlord in writing if requesting lock changes based on safety.
3. Is my landlord required to fix or change broken locks?
   Landlords are generally responsible for ensuring working locks for habitability. You should report any issues in writing and allow a reasonable time for repair.

   You can contact the Missouri Attorney General’s Office for tenant-landlord complaints, or seek court assistance if you face retaliation or danger.
