Smart Locks vs. Traditional Locks: Which One Should You Choose?

As technology continues to evolve, so do the ways we secure our homes. The age-old question of whether traditional locks are sufficient or if smart locks are the future remains a hot debate among homeowners. With rising concerns over home security, convenience, and integration with smart home systems, choosing the right lock is crucial.

Are smart locks the future, or do traditional locks still offer unbeatable reliability? In this guide, we’ll explore the pros and cons of both, compare their security features, and help you decide which option suits your home best.

Traditional Locks: How They Work & Pros/Cons

How Traditional Locks Work

Traditional locks operate using mechanical components such as pins, tumblers, levers, or latches. The most common type, the pin tumbler lock, consists of a series of small pins inside a cylinder. When the correct key is inserted, the ridges on the key align the pins at the shear line, allowing the cylinder to turn and unlock the door.

Other variations, such as mortise locks, deadbolts, and lever locks, use similar mechanical principles but with varying degrees of complexity and security. Traditional locks are typically made of metal, providing strong physical resistance against brute force attacks.

While mechanical locks have been the foundation of home security for centuries, their effectiveness largely depends on the type of lock and how well it is installed. Higher-grade traditional locks, like ANSI Grade 1 deadbolts, offer maximum durability and protection against forced entry.

Common Types of Traditional Locks

Understanding the different types of traditional locks can help homeowners choose the best security option for their doors. Here are some of the most widely used traditional locks:

1. Deadbolt Locks

  • One of the most secure types of locks, ideal for exterior doors.
  • Uses a solid metal bolt that extends into the door frame, making it highly resistant to forced entry.
  • Available in single-cylinder (operated by a key outside and a thumb-turn inside) and double-cylinder (requires a key on both sides) variants.

2. Knob & Lever Locks

  • Commonly found on interior doors rather than exterior entry points.
  • The locking mechanism is inside the knob or lever handle, making it more susceptible to break-ins.
  • Not recommended as a standalone security measure for front doors.

3. Mortise Locks

  • Frequently used in commercial and high-security residential applications.
  • More complex and robust than standard deadbolts, as they are installed inside a door rather than on its surface.
  • Offers enhanced resistance against tampering and break-ins.

4. Padlocks

  • Portable locks used for securing gates, sheds, lockers, and storage units.
  • Available in key-operated and combination variants.
  • Can be easily cut with bolt cutters unless made from high-strength materials like hardened steel.

5. Cam Locks & Rim Locks

  • Often found on cabinets, mailboxes, and safes.
  • Not designed for high-security applications but useful for securing personal items.

As smart locks become increasingly popular, homeowners often have concerns about security, reliability, and functionality. Below, we answer some of the most common questions about smart locks to help you make an informed decision.

1. Can Smart Locks Be Hacked?

Yes, like any internet-connected device, smart locks can be hacked if not properly secured. However, the risk of hacking is significantly reduced if you follow best security practices.

Smart locks that connect via Wi-Fi or Bluetooth can be vulnerable to:

  • Brute-force attacks on weak passwords
  • Man-in-the-middle attacks (where hackers intercept signals)
  • Bluetooth vulnerabilities (older models may lack proper encryption)
  • Credential theft (if your smartphone or smart lock app is compromised)

How to Prevent Smart Lock Hacking:

  • Use strong, unique passwords for your smart lock app and Wi-Fi network.
  • Enable two-factor authentication (2FA) if the lock supports it.
  • Keep firmware and software updated to patch security vulnerabilities.
  • Use encrypted networks and avoid public Wi-Fi when accessing your lock remotely.
  • Disable unnecessary features, like Bluetooth auto-unlock, if you don’t need them.

Most reputable smart lock brands use bank-grade encryption (AES-128 or AES-256) to protect communication between devices. Choosing a smart lock with end-to-end encryption and secure cloud storage further enhances security.

2. What Happens If the Battery Dies in a Smart Lock?

Smart locks rely on batteries (usually AA, CR123, or rechargeable lithium-ion). If the battery dies, most smart locks don’t immediately stop working—they provide low-battery warnings well in advance through:

  • Push notifications to your phone
  • LED indicators on the lock
  • Audible alerts when locking/unlocking

However, if the battery completely drains, you can still regain access through one of the following methods:

Ways to Unlock a Smart Lock with a Dead Battery:

  1. Physical Key Backup – Some smart locks, like Schlage Encode or Yale Assure Lock 2, have a traditional keyhole for manual unlocking.
  2. 9V Battery Backup Port – Many models, such as Ultraloq U-Bolt Pro Wi-Fi, allow you to temporarily power the lock by touching a 9V battery to the terminals.
  3. Emergency External Battery Pack – Some high-end smart locks come with an emergency battery pack that can be plugged in for temporary power.
  4. Smart Home Automation (If Still Connected) – If your lock is integrated with home automation systems, you might be able to trigger unlocking through another connected device.

To avoid getting locked out, always check battery levels regularly and replace them as soon as you receive a low-battery warning.

3. Are Smart Locks Safe if the Internet Goes Down?

Yes, most smart locks still function even if the internet goes down. However, your ability to remotely access the lock via an app or voice assistant will be disabled.

Here’s how different smart lock types behave when offline:

  • Bluetooth Smart Locks (like Level Lock+): Continue working normally with smartphones within range.
  • Wi-Fi Smart Locks (like August Wi-Fi Smart Lock): Local unlocking works, but remote control is unavailable.
  • Z-Wave Smart Locks (like Yale Assure Lock 2): Continue functioning if connected to a smart home hub, but may lose advanced automation.
  • Keypad & Biometric Smart Locks: Work without internet, allowing PIN code or fingerprint entry.

To ensure uninterrupted access, always have a backup method, such as a physical key, keypad entry, or biometric scan.

4. Can I Still Use a Traditional Key with a Smart Lock?

Yes, many smart locks offer traditional key access in case of emergencies or for users who prefer a backup option.

Smart locks that retain key access include:

  • Schlage Encode Plus
  • Yale Assure Lock 2 (with key option)
  • Kwikset Halo
  • Ultraloq U-Bolt Pro

However, some models, like the August Wi-Fi Smart Lock, retrofit onto existing deadbolts and allow users to continue using their original keys. Others, like the Level Lock+, are completely keyless, relying on digital access only.

If keeping a physical key backup is important to you, choose a hybrid smart lock that supports both digital and mechanical access.

5. Do Smart Locks Work During a Power Outage?

Most smart locks are battery-operated and do not rely on household electricity, meaning they continue working during power outages. However, Wi-Fi-enabled features will be disabled if your home loses internet.

If your smart lock is part of a wired security system, such as one integrated with a smart home hub or an electric strike lock, it may require backup power (UPS or battery backup) to function.

To avoid any issues, check that your smart lock has:

  • A long-lasting battery with backup options.
  • A key override or external battery port for emergency access.
  • Local unlocking methods (e.g., PIN codes or fingerprint recognition).

6. Can I Give Temporary or Guest Access with a Smart Lock?

Yes, most smart locks allow you to create temporary, one-time, or scheduled access codes for guests, house cleaners, Airbnb renters, or maintenance workers.

Smart locks that support guest access include:

  • August Wi-Fi Smart Lock – Send temporary codes via the August app.
  • Schlage Encode Plus – Manage up to 100 access codes for different users.
  • Yale Assure Lock 2 – Set scheduled access times for guests.
  • Kwikset Halo – Allows guest access via the Kwikset app.

This feature is particularly useful for rental properties, vacation homes, and frequent guests, ensuring secure, trackable access without the need for physical keys.

7. Do Smart Locks Work in Cold or Rainy Weather?

Most high-quality smart locks are weatherproof and built to withstand extreme temperatures, rain, and humidity.

For example:

  • Ultraloq U-Bolt Pro Wi-Fi has an IP65 weatherproof rating and works in temperatures from -22°F to 149°F.
  • Schlage Encode Plus is built with durable metal housing and is resistant to rain and humidity.
  • Yale Assure Lock 2 functions in temperatures as low as -30°F.

However, capacitive touchscreens may sometimes be less responsive in extreme cold, and fingerprint sensors may struggle with wet fingers. If you live in an area with harsh winters, consider a lock with physical key or keypad backup.

8. How Long Do Smart Lock Batteries Last?

Battery life varies based on:

  • Lock usage frequency
  • Connectivity type (Wi-Fi consumes more power than Bluetooth or Z-Wave)
  • Temperature conditions

Typical battery life estimates:

  • Wi-Fi Smart Locks – 3 to 6 months (e.g., August Wi-Fi, Schlage Encode)
  • Bluetooth/Z-Wave Smart Locks – 9 months to 1 year (e.g., Yale Assure, Level Lock+)
  • Rechargeable Battery Models – 6 months (some high-end smart locks)

To extend battery life:

  • Use lithium batteries instead of standard alkaline.
  • Turn off unnecessary features like continuous Wi-Fi polling.
  • Regularly check battery levels and replace them proactively.
