Do Landlords Need To Change Locks Between Tenants?

When it comes to being a landlord, there are many responsibilities to juggle. From finding tenants to maintaining the property, it can sometimes feel like a never-ending game of whack-a-mole. One question that often arises is whether landlords need to change locks between tenants. Let’s dive into this topic and explore the pros and cons.

The Importance of Security

Security should always be a top priority for landlords. Keeping your tenants safe and protecting their belongings is not just ethical, but also ensures higher tenant satisfaction and reduces potential legal liabilities (1). After all, a happy tenant is less likely to move out or file complaints.

The Risks of Not Changing Locks

Continuing with the same locks from one tenant to another opens up several potential risks:

  1. Unauthorized access: Without changing the locks, you risk previous tenants having unauthorized access to the property.
  2. Key duplication: Previous tenants may have made duplicates of their keys during their tenancy without your knowledge.
  3. Lost keys: There’s always a chance that some keys belonging to previous occupants could be lost or misplaced.

To emphasize this point further, consider this quote from security expert John Doe:

“Not changing locks between tenants is like leaving an apple pie on your windowsill while inviting burglars for tea. “

Legal Obligations

Apart from moral obligations, landlords also have legal responsibilities when it comes to lock changes:

State Laws Vary

Laws regarding lock changes vary depending on the state or country in which you operate as a landlord. It’s essential to familiarize yourself with local laws and regulations pertaining specifically towards rental properties.

Warranty of Habitability & Reasonable Security Measures

The majority of states include an implied warranty of habitability in every lease agreement (2). This means that landlords are required to maintain a safe living environment for tenants. Taking reasonable security measures, such as changing locks between tenancies, can help satisfy this obligation.

Negligence & Legal Consequences

If a landlord fails to change locks and a break-in occurs or the new tenant’s possessions are stolen, they could potentially face legal consequences due to negligence. Being aware of the potential risks and taking steps to mitigate them will always be in your best interest as a landlord.

Factors to Consider

While the importance of changing locks between tenants is clear, there are factors that might influence your decision:

Rekeying vs. Changing Locks

Rekeying involves altering the inner workings of the lock so that existing keys no longer work. It’s generally less expensive than replacing all locks entirely (3) and is an option worth considering if you have confidence in the current lock system’s durability.

Age & Condition of Locks

Consider how long previous tenants resided on your property and whether they treated everything with care or if wear-and-tear might have taken its toll on heavily used locks. If you suspect any issues with functionality or security after inspecting the locks, it may be wise to replace them altogether.

Number of Units & Control Over Keys

The scale at which you operate also plays a significant role in decision-making. For larger properties with many units under one roof, exercising control over keys becomes more challenging. In such cases, simplifying things by replacing locks for each new occupant can provide peace of mind for both landlords and tenants alike.

Advantages and Disadvantages

As there are two sides to every coin, let’s take a balanced look at both advantages and disadvantages when considering lock changes between tenants:


  • Enhanced Security: Changing or rekeying locks ensures unauthorized access is minimized.
  • Greater Tenant Satisfaction: A secure living environment leads to happier tenants who are more likely to stay and take better care of the property.
  • Legal Compliance: By taking reasonable security measures, you protect yourself from potential legal issues.


  • Costs: Changing locks or rekeying can result in additional costs for a landlord.
  • Time-consuming: Replacing or rekeying locks takes time and effort, which might be an inconvenience if you have quick turnover between tenants.
