For landlords and property managers, securing rental units is not just about preventing break-ins—it’s about streamlining operations, enhancing tenant satisfaction, and reducing long-term liabilities. Traditional locks have served their purpose for decades, but with advancements in home automation, smart locks are emerging as a compelling alternative. The question remains: Is it truly worth upgrading to a smart lock for rental property security?
The answer depends on several factors—your budget, the type of property, tenant expectations, and your management style. While smart locks offer undeniable convenience and improved access control, they also come with upfront costs and technical considerations. This article breaks down the practical realities, evaluates key trade-offs, and provides actionable insights to help property owners make an informed decision.
Enhanced Security Features of Smart Locks
One of the most significant advantages of smart locks over traditional deadbolts is the level of granular control they provide. Unlike mechanical keys, which can be duplicated without the landlord’s knowledge, smart locks allow for digital access that can be monitored, revoked, or time-limited remotely.
Modern smart locks typically support multiple authentication methods, including PIN codes, smartphone apps, fingerprint scanners, and even voice commands via smart assistants like Alexa or Google Assistant. Many models also integrate with home security systems, sending real-time alerts when someone unlocks the door—useful for detecting unauthorized entry or verifying maintenance visits.
Additionally, smart locks eliminate common security risks associated with physical keys:
- No lost or stolen keys to worry about rekeying.
- No need to trust third-party vendors with master keys.
- Immediate deactivation of access upon tenant move-out.
Cost-Benefit Analysis: Are Smart Locks Worth the Investment?
Smart locks range from $100 to over $300 per unit, depending on brand, features, and installation complexity. When managing multiple units, this cost can add up quickly. However, when viewed through the lens of long-term savings and operational efficiency, the investment often pays off.
Consider the recurring expenses of traditional lock management:
- Rekeying fees: $50–$150 per unit after every tenant turnover.
- Emergency lockouts: Service calls for stranded tenants or misplaced keys can cost $75+ each.
- Lost key liability: If a tenant loses a key, you may need to rekey immediately for safety, regardless of turnover timing.
In contrast, smart locks reduce or eliminate these recurring costs. Once installed, access codes can be reset instantly at no extra charge. Some models even allow temporary guest codes for cleaners or contractors, eliminating the need for physical key exchanges.
“Landlords who switch to smart locks typically recoup their initial investment within 12 to 18 months through reduced maintenance and rekeying costs.” — Jason Reed, Property Technology Consultant at UrbanLease Advisors
Comparison: Smart Locks vs. Traditional Locks for Rentals
| Feature | Smart Locks | Traditional Locks |
|---|---|---|
| Upfront Cost | $100–$300 per unit | $20–$50 per lock |
| Rekeying Cost | $0 (digital reset) | $50–$150 per turnover |
| Access Control | Remote, time-limited, multi-user | Physical keys only |
| Tenant Move-Out Process | Instant code deactivation | Must rekey or risk exposure |
| Maintenance & Support | Battery changes, Wi-Fi dependency | Key jams, wear and tear |
| Integration | Works with security systems, apps | None |
While smart locks have higher initial costs, their long-term value becomes clear when factoring in labor, security, and scalability. For landlords managing five or more units, the cumulative savings on rekeying alone can justify the upgrade.
Real-World Example: A Landlord’s Experience
Mark Thompson owns three duplexes in Austin, Texas, housing six rental units. For years, he relied on traditional keyed locks, rekeying each unit between tenants. After a former tenant claimed they never returned a key—and Mark had to rekey two units preemptively—he began researching alternatives.
He invested in mid-tier smart locks with keypad and Bluetooth access, spending approximately $180 per unit. Installation took less than 30 minutes per door using existing deadbolt hardware. Within the first year, he saved over $400 in rekeying fees and reduced emergency service calls by 70%.
“The biggest win was peace of mind,” Mark said. “I used to worry about who might still have a key. Now, I deactivate access the day the lease ends. Plus, my tenants love not having to carry keys.”
He did encounter one issue: a lock ran out of batteries during a power outage, but since it still accepted a physical key override, access wasn’t blocked. He now sets monthly calendar reminders to check battery levels across all units.
Key Considerations Before Upgrading
Before switching to smart locks, landlords should evaluate several critical factors to ensure a smooth transition and avoid unintended complications.
1. Internet and Power Reliability
Most smart locks require consistent power (via batteries or hardwiring) and some rely on Wi-Fi or Bluetooth connectivity. In areas with frequent outages, choose models with backup options like physical key entry or offline PIN access.
2. Tenant Acceptance and Privacy
Some tenants may be wary of smart locks due to privacy concerns—especially if logs track who enters and when. Be transparent about data usage. Only monitor access for security or maintenance verification, not surveillance.
3. Legal and Lease Compliance
In some jurisdictions, landlords must notify tenants of electronic monitoring or obtain consent before installing smart locks. Check local landlord-tenant laws. It’s wise to update lease agreements to include terms about digital access, data retention, and lockout procedures.
4. Compatibility with Existing Doors
Not all smart locks fit every door type. Measure bore diameter, backset, and door thickness before purchasing. Most standard residential doors accommodate popular models like August, Schlage, or Yale, but older or reinforced doors may require adapters.
Step-by-Step Guide to Upgrading Rental Property Locks
If you decide smart locks are right for your property, follow this structured approach to ensure a seamless rollout:
- Assess Your Portfolio: List all units and note door types, current lock models, and tenant lease end dates.
- Set a Budget: Include cost per lock, installation tools, and potential contractor fees if DIY isn’t feasible.
- Select a Reliable Model: Prioritize brands with strong encryption, offline access, and mobile app reliability.
- Notify Tenants in Advance: Send a formal notice explaining the upgrade, its benefits, and any temporary access changes.
- Schedule Installation: Coordinate with current tenants for access; consider doing upgrades during turnover to minimize disruption.
- Test and Train: Demonstrate how to use the lock, set personal codes, and troubleshoot basic issues like low battery alerts.
- Update Emergency Protocols: Ensure maintenance staff know how to gain access during outages or system failures.
- Monitor and Maintain: Schedule quarterly checks for battery life, firmware updates, and physical wear.
Essential Smart Lock Checklist for Landlords
Use this checklist before, during, and after installation to ensure a secure and compliant transition:
- ✅ Research local laws on electronic access and tenant privacy
- ✅ Choose a lock with physical key override for emergencies
- ✅ Confirm compatibility with your door’s dimensions and strike plate
- ✅ Enable auto-lock and tamper alerts in the app settings
- ✅ Create unique access codes for each tenant (never share master codes)
- ✅ Document code assignments and deactivation dates
- ✅ Provide tenants with written instructions and support contacts
- ✅ Set up cloud backups or local storage for access logs (if applicable)
- ✅ Plan for battery replacement schedule (typically every 6–12 months)
- ✅ Review insurance policy—some providers offer discounts for smart security upgrades
Frequently Asked Questions
Can tenants hack or bypass a smart lock?
High-quality smart locks use military-grade encryption and are designed to resist common hacking methods like brute-force PIN attacks. Most lock out users after multiple failed attempts. However, weak passwords (e.g., \"1234\") increase vulnerability. Encourage tenants to use complex, non-obvious codes.
What happens if the smart lock battery dies?
Reputable models send low-battery alerts weeks in advance via the app. Even if the battery dies completely, nearly all smart locks include a physical key override or a 9-volt battery boost terminal to provide temporary power and unlock the door.
Do smart locks increase property value or rentability?
Yes. A 2023 National Apartment Association survey found that 68% of renters view smart home features as important, with smart locks ranking among the top three desired amenities. Properties equipped with modern security tech often lease faster and can command a 3–5% rent premium in competitive markets.
Final Thoughts: Making the Smart Move
Upgrading to smart locks isn’t just a trend—it’s a strategic enhancement to rental property management. The combination of improved security, reduced operational costs, and increased tenant satisfaction makes a strong case for adoption, especially for landlords with multiple units or high turnover rates.
While the initial investment may seem steep, the long-term savings on rekeying, emergency services, and vacancy periods often outweigh the upfront expense. More importantly, smart locks provide control and visibility that traditional keys simply cannot match.
As rental expectations evolve and technology becomes more accessible, smart locks are transitioning from luxury add-ons to essential components of modern property security. Whether you manage one unit or a full portfolio, evaluating this upgrade could be one of the most impactful decisions you make this year.
