What Are Smart Locks?
Smart locks are electronic access control devices that replace—or retrofit—traditional deadbolts, enabling keyless entry via smartphone apps, PIN codes, biometric scans, or voice commands.
- Connectivity: Use Wi-Fi, Bluetooth, Z-Wave or Zigbee to communicate with your home network.
- Access Methods: Temporary guest codes, fingerprint scans, or integration with smart assistants like Alexa and Google Home.
- Remote Control: Lock/unlock doors from anywhere; receive real-time notifications on door activity. (Homebuilding)
Why You’re Considering Smart Locks
- No more lost keys
- Granular access permissions
- Integration into wider home automation systems
What Are Traditional Locks?
Traditional locks—primarily mechanical deadbolts and padlocks—use physical keys and tumblers. They remain the industry standard for decades, prized for:
- Simplicity: No electronics, batteries, or firmware updates.
- Durability: Often Grade 1 or Grade 2 ANSI/BHMA certified for physical strength. (The Spruce)
- Cost-Effectiveness: Upfront costs can be 50–75% lower than smart counterparts.
Smart Lock Security Features
Smart locks pack powerful security-enhancing tools—if you configure them properly:
- Two-Factor Authentication (2FA)
- Combines PIN entry with smartphone confirmation.
- Reduces risk of unauthorized codes being used. (Great Valley Lockshop)
- End-to-End Encryption
- AES-256 encryption protects data between lock and app.
- Protects against eavesdropping and replay attacks. (Homebuilding)
- Tamper Alerts & Auto-Lock
- Real-time notifications on forced entry attempts.
- Automatic re-locking after a configurable interval. (Homebuilding)
- Firmware Updates
- Patches known vulnerabilities and hardens defenses.
- You must stay on top of updates to avoid exposure.
Traditional Lock Strengths
Don’t underestimate mechanical locks. They deliver proven, no-frills security:
- Physical Resistance
- High-grade deadbolts withstand 1000+ pounds of force. (The Spruce)
- Pick-resistant pins and hardened steel plates.
- No Cyber Attack Surface
- Zero electronic components = zero hacking.
- Cannot be disabled by malware or drained batteries.
- Simplicity & Reliability
- Works in power outages and doesn’t depend on network uptime.
- Minimal maintenance beyond occasional lubrication.
Key Vulnerabilities Compared
| Aspect | Smart Locks | Traditional Locks |
|---|---|---|
| Attack Surface | Software flaws, wireless interception, phishing, weak default passwords. | Lock picking, bumping, brute-force kicking. (bowleylockcompany.com) |
| Failure Mode | Battery drain, firmware bugs, network downtime. | Key loss, broken key in lock. |
| Unauthorized Access Likelihood | ~1 in 50,000 when secure setup with 2FA and AES-256, but rising IoT breaches. (JumpCloud) | ~1 in 10,000 for skilled lock-pickers; forced entry accounts for ~66.8% of break-ins. (bowleylockcompany.com) |
| Cost to Bypass | <$100 in DIY hacking tools & software exploits. | ~$20–$40 in lock-picks or bump-keys. |
| Maintenance | Monthly firmware checks, battery replacements every 6–12 months. | Annual lubrication and inspection for wear. |
2025 Market Trends & Adoption
- Market Growth: Smart lock global market will hit $3 billion in 2025, up from $2.66 billion in 2024 (CAGR 12.7%). (The Business Research Company)
- Adoption Drivers:
- Rising home automation demand
- Enhanced cybersecurity awareness
- New builds increasingly standardizing on IoT-ready hardware
- Emerging Risks:

| Remote Control | ✔ (Anywhere via internet) | ✘ |
| Physical Durability | ✔ (ANSI Grade 1–3 ratings) | ✔ (Typically Grade 1–2) |
| Cost (Upfront) | $100–$350+ | $20–$100 |
| Maintenance Requirements | Firmware updates, battery swaps | Lubrication, key duplication |
| Failure Risks | Cyber-attack, dead battery | Lock picking, bumping |
Actionable Tips: Maximizing Your Lock Security
Whether you choose smart or traditional, here’s how you can strengthen your defenses:
- For Smart Locks
- Enable 2FA: Always pair codes with app confirmations.
- Use Strong, Unique PINs: Avoid “1234” or birthdays.
- Keep Firmware Updated: Check monthly for patches.
- Secure Your Wi-Fi: Use WPA3 encryption on your home network.
- For Traditional Locks
- Upgrade to Grade 1/2 Deadbolts: Look for ANSI/BHMA certification.
- Install Reinforced Strike Plates: Use 3-inch screws into the frame.
- Rotate Keys Periodically: Rekey every 1–2 years if you suspect unauthorized duplication.
- Add Secondary Deterrents: Door jammers or security bars.
- General Best Practices
- Outdoor Lighting & Cameras: Visible cameras deter both pickers and hackers.
- Regular Security Audits: Test your locks and change protocols annually.
- Stay Informed: Follow IoT security advisories—like the IBM X-Force Threat reports—for emerging risks. (JumpCloud)
Frequently Asked Questions
Q1: Can hackers really break into smart locks?
A: Yes—if you skip updates or use weak passwords. Over 50% of IoT devices, including locks, have critical vulnerabilities (JumpCloud). Always enable 2FA and maintain strong encryption.
Q2: Are high-grade deadbolts pick-proof?
A: No lock is 100% pick-proof, but Grade 1 deadbolts with spool pins and anti-pick technology reduce pick success to under 1% for average burglars (bowleylockcompany.com).
Q3: What if my smart lock’s battery dies?
A: Many models include emergency key overrides or external battery contacts. Always check for backup options before purchase.
Q4: Which is more cost-effective long term?
A: Traditional locks cost less upfront and have minimal upkeep. Smart locks cost more but add convenience and remote management—worth it if you value those features.
Q5: Can I retrofit my existing lock to become “smart”?
A: Yes—retrofit smart lock kits (e.g., SwitchBot Lock) clamp onto your existing deadbolt’s thumbturn (TechRadar).
Conclusion
In 2025, both smart and traditional locks have their place in a layered security strategy.
- Smart locks offer unmatched convenience, remote control, and integration—but demand diligent cyber hygiene: strong PINs, 2FA, firmware updates, and secure Wi-Fi.
- Traditional locks deliver rock-solid physical security with zero digital attack surface—but lack the flexibility of keyless entry and guest access management.
Ultimately, you know your priorities best. Use this guide to assess your threat model, weigh costs, and take concrete steps—whether digital or mechanical—to fortify your home against cyber and physical intruders alike.
