With an attractive, sleek design, the Yale Assure Lock 2 connects via WiFi and Bluetooth and can be controlled from your smartphone. It also has a touchpad that allows users to enter with a PIN code.

Powered by four AAA batteries, the lock also features a fingerprint reader if users prefer a quick and secure biometric credential.

As an additional bonus, there are WiFi modules that allow you to connect to Amazon Alexa, Google Home, and more, and Z-Wave modules that connect to Ring Alarm, Samsung SmartThings, and more.

4. August WiFi Smart Lock

The August WiFi Smart Lock is small and discreet, WiFi-enabled, and easy to install, making it another viable option.

Unlike many other smart locks on the market, the August WiFi Smart Lock only requires you to change the part of your deadbolt that’s inside your apartment. This means your tenants can still keep their original keys if they choose.

The smart lock also comes with a sensor that can tell the lock if your door is closed, which then enables auto-lock and unlock via WiFi or Bluetooth. August can automatically lock when your door is shut, or unlock when you approach the door. Additionally, you can create temporary virtual keys through the mobile app.

Installing this smart lock takes only about 15 minutes.

5. Nest X Yale Lock with Nest Connect

Designed to work with the Nest app, the Nest X Yale Lock with Nest Connect allows you to lock and unlock your door with a tap of your finger, no matter where you are. Residents can create up to 20 passcodes so that house cleaners, dog walkers, and other service providers can access the unit while no one is home.

This smart lock comes with some additional features, like an automated reminder so that tenants never have to worry if they’ve left the door unlocked. The Nest X is easy to install with just a screwdriver, and the setup appears to be fairly intuitive.

A unique feature that we like in this smart lock is that it has a small speaker on the right side and two terminals on the bottom in case the lock’s batteries die.

As of now, this smart lock may only support voice commands through Google Assistant.

6. Halo WiFi-Enabled Smart Door Lock

The Halo Smart Door Lock works with the Kwikset app to let you monitor door activity and lock or unlock your door remotely. Both property managers and residents can create codes for anyone who needs to access the apartment. And Halo makes it easy to restrict those codes by date or time.

This lock connects to Bluetooth so you can enter using your smartphone. It also connects to Amazon Alexa and Google Assistant so you can lock or unlock the door with just your voice.

A drawback to this smart lock is that the battery life may be short — users have reported that it often lasts less than six months.

7. Schlage Connect Smart Deadbolt

The Schlage Connect Smart Deadbolt is user-friendly and easy to install. This dependable lock is ANSI/BHMA Grade 1, giving it the highest home security rating. The touchscreen is fingerprint-resistant and has loud built-in alarm sensors.

When your tenants are away, they can turn on vacation mode to disable all codes and allow entry with the key only. The lock connects with Zigbee-certified home automation systems, so if your tenants have smart lights, they can set the lights to turn on when the door is unlocked or turn off when they leave.

One caveat: This lock may be a bit larger than most other smart locks, so if you’re seeking a more minimalist option, this may not be the best choice for you.

8. Obsidian Keywayless Electronic Touchscreen Smart Deadbolt

The Obsidian Keywayless Electronic Touchscreen Smart Deadbolt by Kwikset keeps it simple, offering just a touchscreen keypad. Since this lock lacks a Bluetooth or WiFi connection, you may only be able to unlock the door when you’re physically in front of it. Further, residents may only generate access codes from the keypad itself, meaning they may not be able to grant access to guests remotely.

That said, this Obsidian smart deadbolt is easy to use and offers impressive security features. It boasts a technology that prevents code detection from marks on the touchscreen as well as an alarm that rings after three failed attempts to enter the code. Plus, its auto-lock feature locks the door after 30 seconds.

10. August Smart Lock + Connect

The August Smart Lock + Connect is quick to install because it simply attaches to the existing deadbolt on the inside of the door. The outside door lock remains the same, so existing keys still work.

This smart lock connects to Bluetooth and is WiFi-enabled, which means you can lock and unlock your door from anywhere. Additionally, the door can unlock automatically when you approach with your smartphone. You can also provide guest access for visitors.

One caveat: The August Smart Lock only controls your deadbolt. If your tenants like using additional locks as well, this might not be your best option.

11. Wyze Lock

The Wyze Lock may be a great option for smaller budgets, as it is a relatively affordable smart lock on the market. That said, it may lack some of the bells and whistles that other smart locks offer. Notably, it does not connect to smart assistants and requires a gateway to connect to WiFi.

However, this smart lock does offer solid security features for the price. It alerts you if you ever leave your door unlocked, and the app also supports two-factor authentication.

What are smart locks?

Smart locks are electromechanical locks that allow users to unlock doors and manage access with smartphones, PIN codes, key cards, or fobs instead of physical keys. A smart lock may either replace your existing door lock hardware or be installed on top of an existing deadbolt.

Benefits of smart locks include:

  • Control access from anywhere
  • No physical keys to manage, replace, or hand off to visitors
  • Notifications/door release information on activity and lock usage
  • Improve the tenant experience
  • Save time for property staff


Types of smart locks

  • Deadbolt: A deadbolt lock has a deadbolt that must be actively retracted to allow the door to be unlocked.
  • Lever: A lever lock uses levers to prevent the bolt from opening the lock.
  • Interconnected: An interconnected lock is a lever handle and a deadbolt connected together for single-motion egress.
  • Mortise: A mortise lock combines the deadbolt and the latch into one lock. The term ‘mortise’ refers to the rectangular pocket created in the door edge for this lock.

Smart lock FAQs

Commonly asks questions about smart locks:


How do smart locks work?

Smart locks are designed to replace traditional locks that require a physical key. If you’ve ever locked yourself out, lost your keys, or fumbled to find keys in your bag, you’ll benefit from a smart lock.

When you install a smart lock, you can unlock your door without using a key.

With a smart lock, you can unlock the door with:

  1. A mobile app on your smartphone
  2. A PIN code you enter on the smart lock’s keypad

That said, some smart lock models still have a keyhole that allows you to use a traditional key.

While some smart locks attach to your existing deadbolt, others replace your deadbolt entirely. If you’re planning to install smart locks on every door in your apartment building, we recommend speaking with a professional installer who can advise you on which system is best.

Regardless of which type you choose, your smart lock will require a wireless connection like Bluetooth or WiFi.

How do smart locks connect to the internet?

Smart locks connect to the internet via Wi-Fi, Bluetooth, Z-Wave, Zigbee, or cellular networks.

Many smart locks use WiFi or Bluetooth technology, allowing them to communicate with an app on your smartphone. This allows you to control and monitor access remotely.

Other smart locks connect to the internet through a home automation system such as Z-Wave or Zigbee. These systems allow the lock to be controlled from a central hub and also allow it to interact with other connected devices in your home.

Finally, some smart locks use cellular networks such as 4G or 5G, which allows them to connect to the internet without relying on another device. This gives you greater control and flexibility when it comes to managing access remotely.


Types of smart lock connectivity

What makes smart locks smart? Their connection to the internet. And there are a few ways that different smart lock models can establish that connection.

The main types of smart lock connectivity include:

  • WiFi: Connect directly to the internet using the building’s WiFi connection. No gateway or hub is required. Updates to the lock (access and event logs) happen immediately, but WiFi smart locks have shorter battery life.
  • Z-Wave: Can’t connect directly to the internet. Instead, they must connect to a separate Z-Wave hub, which connects to the internet. Z-Wave smart locks require less power and, therefore, have longer battery life. Multiple locks can share one Z-Wave hub. However, you may be concerned about ensuring the hub stays plugged in.
  • Bluetooth: Some smart locks use Bluetooth technology to authorize access from a device (generally a smartphone) when in close proximity to the lock.
  • Hub/gateway/bridge: These locks require a hub or WiFi bridge to connect to the internet. In this system, all of a building’s smart locks connect to one gateway/hub/bridge, creating a network. These locks require less power and enjoy a longer battery life. (Required for Z-Wave and some WiFi smart locks.)
  • Hardwired: This requires power to operate and communicate with the access control software to allow or deny access. Wires run from the lockset through the door and frame back to the control panel and power supply.


Online vs. offline smart locks

  Always Online Locks Heartbeat / Sleep Mode Locks Offline Locks
Advantage Real-time updates for access & events. Conserves battery; access & events are updated as soon as the connection is established. Lower costs; no WiFi connection needed.
Connectivity Consumes more power, so battery life is shortened

2 ways to establish a connection:

1. Scheduled connection – connects every set time period.

2. Touch or interaction with the lock initiates the connection.

Need the card/fob/phone to transfer data to/from the lock.

A person must engage each lock to pull data and update access on each lock.

Access & event data latency Real-time updates for access and events — no delays. Sleep/heartbeat mode extends the battery but leads to delays in access management updates. The lock needs to connect to implement changes to access permissions. No real-time events/reporting (door releases) — data is stored on the locks.
Requires a manual interaction to transmit access management updates and pull event history.
Integration features & limitations Supports PIN access, mobile credentials, & fob/card access. Supports PIN access, mobile credentials, & fob/card access. Although they support PIN access, mobile credentials, & fob/card access, there are a finite number of users per lock depending on manufacturer and lock type.


Why you should invest in smart locks

Apartment amenities have always been a way to attract and retain residents. But many property managers wonder which amenities will actually pay off.

These days, modern renters of all ages seek technology-powered amenities like smart video intercoms and smart door locks. This goes to show that your residents prioritize convenient, seamless property access.

According to a study conducted by Entrata, keyless entry is the second most desired smart apartment amenity. In fact, 45% of renters believe that physical door keys will be obsolete within the decade.

Delighting residents is key to your bottom line. Investing in smart locks is a simple way to boost resident retention and reduce turnover.


Integrating smart locks with other proptech

An added benefit of smart locks is their ability to integrate with other smart home technologies.

For the ultimate property access experience, integrate a smart lock solution with a cloud-based video intercom like ButterflyMX. Together, these two proptech solutions enable completely keyless entry from the building’s front door to your residents’ apartments.
