Best For: Tech-savvy users with existing smart home ecosystems.
5. Renter-Friendly and Portable Options
Benefit: Retrofit smart locks, like the SwitchBot Lock, install over existing deadbolts without permanent changes, making them portable smart locks.
- Example: The August Wi-Fi Smart Lock installs in 5–10 minutes and can be removed without damaging the door.
- Impact: Ideal for renters or temporary setups, as landlords retain key access.

- Impact: Saves landlords $50–$100 per rekey, streamlining tenant transitions.
Best For: Property managers and short-term rental hosts.
Cons of Smart Locks
Despite their advantages, smart locks have limitations that may affect your decision. Here are the key drawbacks:
1. Higher Upfront Cost
Drawback: Smart locks are pricier than traditional deadbolts, with premium models costing $150–$350.
- Example: The Schlage Encode ($250–$300) is significantly more expensive than a $30–$50 traditional lock.
- Impact: The initial investment can be a barrier for budget-conscious buyers, especially for multiple doors.
Mitigation: Budget options like the Wyze Lock Bolt ($60–$80) offer basic features at a lower cost.
2. Smart Lock Battery Life and Maintenance
Drawback: Smart locks rely on batteries, requiring regular replacement or recharging, especially for WiFi models.
- Example: The August Wi-Fi Smart Lock lasts 3–6 months on CR123A batteries, which are pricier than AA/AAA batteries.
- Impact: Frequent smart lock maintenance can be inconvenient, and a dead battery could lock you out.
Mitigation: Choose Bluetooth locks (e.g., SwitchBot Lock, 6–12 months) for longer smart lock battery life, and keep spare batteries.
3. Connectivity Issues
Drawback: WiFi and Bluetooth smart locks can face connectivity problems, affecting remote access or app control.
- Example: Users report the August Wi-Fi Smart Lock’s auto-unlock lagging in areas with crowded WiFi networks.
- Impact: Unreliable connectivity can disrupt functionality, requiring smart lock troubleshooting.
Mitigation: Ensure a strong 2.4GHz WiFi signal for WiFi locks or stay within Bluetooth range (30–100 feet).
4. Potential Security Vulnerabilities
Drawback: While smart locks enhance smart lock safety, they’re not immune to hacking or technical failures.
- Example: Weak WiFi passwords or outdated firmware could expose locks like the Schlage Encode to cyberattacks.
- Impact: Cybersecurity risks require proactive measures like strong passwords and firmware updates.
Mitigation: Use two-factor authentication and keep firmware updated to minimize risks.
5. Installation Challenges
Drawback: Full deadbolt replacements require precise smart lock installation, which can be complex for DIYers.
- Example: Installing the Yale Assure Lock 2 (full replacement) may involve drilling, potentially damaging doors if done incorrectly.
- Impact: Renters may need landlord approval, and improper installation can cause mechanical issues.
Mitigation: Opt for retrofit locks like the August Wi-Fi Smart Lock or SwitchBot Lock for simpler installation.
6. Dependency on Technology
Drawback: Smart locks rely on smartphones, apps, or internet connectivity, which can fail during power outages or device issues.
- Example: If your phone dies, you may need a keypad (sold separately for some models) or physical key to enter.
- Impact: Loss of access can be inconvenient, especially without a backup key.
Mitigation: Choose locks with physical key overrides (e.g., Ultraloq U-Bolt Pro) or keep a keypad handy.
