How to Choose a Smart Lock in 2026: A Buying Guide

Smart locks used to be a novelty. Now they're one of the most practical upgrades you can make to your home. No more digging for keys in the rain, no more re-keying after a lost fob, and no more wondering if you locked up before you left for vacation.

But "smart lock" covers a huge range of products, from budget keypad deadbolts to fully connected locks that talk to your entire security system. Picking the wrong one can mean dead batteries at the worst time, a lock that doesn't fit your door, or a device that never actually integrates with the rest of your smart home.

Here's how to think through the decision in 2026.

Start With How You Want to Get In#

Every smart lock offers some combination of these entry methods:

• PIN code / keypad, type in a code, no phone needed
• Smartphone app, unlock via Bluetooth or Wi-Fi from your phone
• Key fob or card, tap or swipe, useful for kids or guests without phones
• Physical key backup, nearly every reputable smart lock still includes one
• Voice or automation trigger, unlock as part of a scene, like "arriving home"
• Biometric (fingerprint), less common on residential locks, but growing

Most households end up using two or three of these regularly. If you have kids who don't carry phones, a keypad or fob option matters more than flashy app features. If you host a lot of guests or short-term renters, temporary or scheduled PIN codes are worth prioritizing.

The Consumer Reports testing team has noted that ease of everyday use, not just security features, is one of the biggest factors separating locks people actually keep using from ones that end up disabled or removed after a few months (Consumer Reports).

Check the Lock's Security Certifications#

Not all smart locks are built to the same physical security standard. Before buying, look for:

• ANSI/BHMA Grade 1, 2, or 3 rating, Grade 1 is the highest residential security and durability rating, Grade 3 is the lowest
• UL certification, indicates the lock has passed independent testing
• Auto-relock and tamper alerts, the lock should re-engage on its own and notify you of forced entry attempts

The American National Standards Institute, alongside the Builders Hardware Manufacturers Association, sets the ANSI/BHMA grading system that most manufacturers reference on their packaging or spec sheets (ANSI). A Grade 1 or Grade 2 deadbolt is generally worth the extra cost over a Grade 3 lock, especially on exterior doors.

Think About Connectivity, Not Just Convenience#

This is where a lot of buyers get tripped up. A smart lock's connection type determines what it can actually do:

Bluetooth-only locks connect directly to your phone when you're within range. They're affordable and simple, but you can't lock or unlock them remotely, and you won't get notifications when you're away from home.

Wi-Fi locks connect straight to your home network, so you can control them from anywhere. This is more convenient but can drain batteries faster and depends on your router staying online.

Hub-connected locks work through a smart home hub or security system panel, which handles the heavy lifting. This tends to be the most reliable option for remote access, automations, and integration with cameras or alarms, since the hub manages the connection instead of the lock itself.

If your main goal is a lock that works seamlessly with door sensors, cameras, and an alarm panel, a hub-connected lock that's part of a broader home automation setup is usually the more dependable choice long term.

Make Sure It Fits Your Door and Your Ecosystem#

Before you buy, measure your door's backset (the distance from the edge of the door to the center of the bolt hole) and confirm the lock is compatible with standard deadbolt preparations. Most U.S. residential doors use a 2 3/8" or 2 3/4" backset, and most smart locks are designed to fit both, but it's worth double-checking the product specs.

Also consider what else is in your smart home, or what you're planning to add:

• Do you already have a security system or cameras from one brand?
• Do you want the lock to trigger anything else, like turning on lights or arming the alarm?
• Will you want to add more devices later, like video doorbells or sensors?

Locks that are part of a complete system, rather than a standalone gadget, tend to offer more useful automations. For example, a lock that can automatically arm your alarm when you leave and lock the door, or disarm it when you unlock the door coming home, is genuinely more useful day to day than a lock that only works by itself.

Battery Life and Backup Access#

Nearly all smart locks run on batteries, typically 4 AA batteries or a proprietary pack. Look for:

• Low-battery notifications sent to your phone, not just a beep on the lock itself
• External battery backup, a 9-volt terminal on the outside lets you jump-start the lock if the batteries die and you're locked out
• Manual key override as a last resort

Battery life varies widely by brand and usage, generally lasting anywhere from a few months to over a year depending on how often the lock is used and whether it's Wi-Fi or Bluetooth. Check manufacturer specs rather than relying on marketing claims, and read recent buyer reviews for real-world battery performance.

Data Privacy and App Permissions#

A smart lock is connected to the internet, which means it's also a data point about who enters and exits your home and when. The Federal Trade Commission has published guidance encouraging consumers to review what data smart home devices collect, how it's stored, and whether it's shared with third parties before connecting a device to your network (FTC).

Before buying, check:

• Whether the manufacturer requires two-factor authentication for the app
• How long access logs are stored and who can view them
• Whether firmware updates are automatic or require manual action

A lock that never gets firmware updates is a lock with security holes that never get patched.

How a Smart Lock Fits Into a Full Security Plan#

A smart lock is a great upgrade, but it's one layer of protection, not the whole plan. The strongest setups pair a quality lock with door and window sensors, motion detection, and cameras that can verify what's actually happening at your door.

If you're building out a more complete home security system, it's worth choosing a lock that's designed to integrate with that system from day one rather than bolting one on later. Vivint locks, for instance, connect directly into the same platform as your cameras, sensors, and alarm panel, so everything works together instead of living in separate apps.

Pricing for a full system varies based on how many devices you add, so it's worth reviewing Vivint's pricing options to see what a bundled setup looks like compared to buying a standalone lock.

You can also pair a smart lock with a video doorbell camera so you can see and speak with whoever's at the door before you ever unlock it remotely, which adds a real layer of verification that a lock alone can't provide.

Questions to Ask Before You Buy#

Before checking out, run through this quick list:

1. Does it fit my door's backset and existing deadbolt hole?
2. What entry methods does it support, and do they match how my household actually enters?
3. What's its ANSI/BHMA grade?
4. Does it connect via Bluetooth, Wi-Fi, or a hub, and does that match how I want to use it?
5. Does it integrate with security cameras, sensors, or an alarm system I already have or plan to get?
6. How is battery life, and is there a backup option if it dies?
7. What's the manufacturer's track record on firmware updates and data privacy?

If you're not sure how a smart lock would fit with your home's current setup, a quick call can help. Vivint's team can walk through your specific home and goals at 866-417-1540, or you can contact Vivint online to get a recommendation tailored to your door types and existing devices.

The Bottom Line#

The best smart lock in 2026 isn't necessarily the one with the most features. It's the one that matches how your household actually comes and goes, meets a solid security grade, and plays well with the rest of your home's security setup. Take the time to measure your door, check certifications, and think about integration before you buy, and you'll end up with a lock you actually trust and use every day.

Common Questions#

Are smart locks as secure as traditional deadbolts?

A quality smart lock with a Grade 1 or Grade 2 ANSI/BHMA rating can be just as physically secure as a traditional deadbolt, since many use the same bolt mechanisms. The added electronics introduce new considerations, like firmware updates and app security, but they don't inherently make the lock weaker.

Can I install a smart lock myself?

Most smart locks are designed for DIY installation and fit standard deadbolt door preparations, typically taking 20 to 30 minutes with a screwdriver. If your door has a nonstandard backset or you want the lock integrated into a full security system, professional installation can help ensure everything is set up and connected correctly.

What happens to my smart lock if the power or Wi-Fi goes out?

Battery-powered smart locks continue to operate on local battery power even during a Wi-Fi or power outage, though remote app control may be temporarily unavailable until connectivity is restored. Nearly all models also include a physical key override as a backup.
