What is a smart lock?

A smart lock is a device that connects to the internet and can be used without a key. It allows users to control entry using a smartphone, keypad, fingerprint reader, or voice command. Most smart locks connect via Wi-Fi, Bluetooth, or Z-Wave, and integrate with smart home systems and voice assistants like Google Assistant.

Smart locks provide keyless entry, eliminating the need for a physical key. Many also support features like auto-lock, auto-unlock, and encrypted activity logs for added home security.

Types of smart locks

• Retrofit locks: Mount over an existing deadbolt
• Full replacement deadbolts: Replace the entire deadbolt lock mechanism
• Integrated smart lock + video: Combine lock functionality with a camera

What’s new for smart locks in 2026

Smart lock technology has advanced rapidly, and the 2026 models are smarter, faster, and more secure than ever. From seamless integration with Apple Home Key to AI-powered security alerts, today’s devices are built to simplify access while enhancing protection. Whether you're upgrading an older model or buying your first smart lock, here’s what’s new this year—and why it matters.

The latest smart lock models may offer offer:

• Built-in Wi-Fi for remote access without bridges or hubs
• Advanced AI alerts for unusual activity and tamper detection
• Support for Matter, Z-Wave, and other smart home devices
• Touchscreen keypads and fingerprint recognition for user-specific access
• Extended battery life and diagnostics via app notifications

Why the Vivint Kwikset Z-Wave Lock Stands Out

• Seamless ecosystem integration: It works directly with Vivint's smart hub, doorbell cams, sensors, lights, and thermostats—no extra bridge is needed. Locking/unlocking can trigger system-wide automation, such as disarming alarms, adjusting lights, or changing the temperature.
• Robust Z-Wave connectivity: This smart lock uses Z-Wave connectivity to keep your locks in communication with your home security system.
• Rich user controls: Supports up to 50 unique access codes, access/activity logs, and remote management through the Vivint app. You also get real-time notifications of lock activity.
• Professional installation & monitoring: Vivint offers professional installation and 24/7 monitoring, which ensures proper setup and ongoing service.

Door compatibility tips

Choosing the right smart lock depends on where it's being installed—here are some tailored tips for different types of doors, especially if you're integrating with a system like Vivint Security.

• Front doors: Prioritize smart deadbolt models with high durability
• Garages/side entries: Go for keypad-based locks with auto-lock
• Interior offices or nurseries: Use Bluetooth-only locks for local-only control
• Sliding or nonstandard doors: Measure door thickness and handle alignment; consider easy installation models

FAQs

Is the installation DIY-friendly?

Technically, yes—some smart locks are designed for easy retrofit installation. And with patience and basic tools, even full deadbolt replacements can be handled by confident DIYers.

But Vivint takes a different approach—and for good reason. Their system is built to work seamlessly with your entire smart home, which means every device needs to be precisely installed, synced, and optimized. That’s why Vivint includes professional installation as part of the experience. Instead of spending your weekend fumbling with screwdrivers, second-guessing compatibility, or risking an insecure setup, you get a trained expert who handles everything for you.

It’s fast. It’s precise. And it ensures your home is protected from day one—no guesswork, no gaps, just peace of mind.

How long is the battery life?

Battery life varies by usage and model, but most smart locks offer between 6 and 12 months. Models with built-in Wi-Fi tend to use more power, while Bluetooth-only or Z-Wave models conserve energy more efficiently.

Can I manage multiple locks remotely?

Yes—smart lock apps from brands like Vivint support multiple devices across different homes or properties. This feature is especially useful for managing several rental listings or entry points within a single residence.

Do smart locks integrate with Google Assistant or Siri?

Most smart locks are designed to be compatible with major voice assistants. Based on your preferred smart home ecosystem, look for support for Google Assistant or Siri.

Can smart locks be used for Airbnb or short-term rentals?

Yes, smart locks are one of the most convenient ways to manage guests' access without handing out physical keys. Create temporary or scheduled codes for each reservation and disable them after checkout.

What if the Wi-Fi goes out or the battery dies?

Most locks retain basic functionality through Bluetooth or a manual key. You’ll temporarily lose remote access, but you can still unlock your door locally. Many smart locks will warn you when batteries are low.

Can I see who accessed the lock and when?

Yes. Most smart lock apps include an activity log that shows which codes were used and when. This feature is particularly valuable for hosts, property managers, and parents.

Why should I get a smart lock?

Smart locks offer more than just convenience—they give you total control over who enters your home and when. Whether you want to monitor your child’s return from school, avoid the hassle of spare keys, or secure an Airbnb without meeting guests in person, smart locks provide real-time access control, alerts, and automation that traditional locks simply can’t match.

Will it work with my existing deadbolt?

The Vivint Smart Lock from Kwikset, does not work as a retrofit on your existing deadbolt. With professional installation as part of a Vivint system purchase, a smart home pro can help get your new lock up and running.

Here's how Vivint's smart lock differs:

• Replacement, not retrofit: Vivint smart lock replaces your entire existing deadbolt, both inside and outside components. It does not mount over your existing hardware.
• Standard door prep required: It expects a standard deadbolt borehole and backset.
• Requires Z-Wave connectivity: Vivint’s locks are Z-Wave enabled and rely on integration with the Vivint Smart Hub for remote access, automation, and notifications.

Is a smart lock really more secure than a regular lock?

When properly configured, yes. Smart locks offer enhanced features like auto-lock, tamper detection, encryption, and activity logs—features you won’t find on a traditional mechanical lock.

Smart locks are a scalable security solution

Smart locks in 2026 combine sleek design, robust security, and seamless smart home integration. Whether you’re upgrading a front door, securing a vacation rental, or streamlining access for kids, caregivers, or guests, today’s smart locks deliver a blend of convenience, safety, and control that traditional deadbolts simply can’t match.

They’re also scalable. You can start with one Wi-Fi smart lock and gradually build a whole-home access system that integrates with your home security devices, cameras, and lighting controls.

Unlike traditional locks, smart locks adapt to your lifestyle. They make life easier when you’re home and safer when you’re away. With features like remote access, user-specific codes, and voice assistant support, they’re the ideal solution for anyone looking to modernize their home’s first line of defense.

If you’re investing in a smarter, safer home, a smart lock is one of the most impactful upgrades you can make. With increasing compatibility, longer battery life, and easier installation, the transition from a mechanical key to a keyless entry lifestyle has never been more accessible or worthwhile.
