Factors to Consider

Retrofit

Retrofit smart locks are quite popular with rental properties and vacation homes as the do not require large scale changes to your locking mechanism. They offer buyers the benefit of added security without extra costs because they allow you to keep your existing hardware, which means you don't have to spend cash making new sets of keys or door alterations. 

Connectivity

Aside from that, most retrofit smart locks also offer the advantage of extended connectivity. For instance, remote access via smartphones or smartwatches, smart alerts, door sensors for automatic locking/unlocking is often part of the package. 

However, it is wise to ensure the retrofit lock is compatible with your existing deadlock system before purchasing.

The leading retrofit lock on the market

A hassle-free solution for buyers looking to upgrade to smart locks, with handy features within a reasonable price range.

Top Features
  • A retrofit device that's compatible with most standard deadlocks.
  • Easy to install and operate.
  • It offers enhanced user control via the smartphone app.

Voted ‘Best Smart Lock 2019' by CNET, the August Smart Lock Pro is the sleeker, more advanced, and third-generation version of the company's locking systems. 

The most convenient feature of the Smart Lock Pro is that it can connect to your existing deadbolt (from the inside) and requires no changes or alterations.

Connectivity

The device can connect to Wi-Fi and grant you advanced user options through a smartphone app. It is also compatible with leading voice assistants, such as Alexa, Google Assistant, and Apple HomeKit

Once you install and power the lock with 4 AA batteries, it will connect to your Wi-Fi through the Bridge, and you can have complete control of the lock from your device via the app. 

Installation

The installation itself takes less than 10 minutes and requires removing the latch from the inside of your door with a screwdriver. Next, you affix the mounting plate and the August locking mechanism, and you're done. 

Remote Controls

When all systems are up and running, buyers can expect the lock to auto-lock and unlock once your Bluetooth enabled phone is in the vicinity. You can also control the device remotely from anywhere in the world. 

At home, you can check the status of your lock without having to resort to the app, due to the Smart Lock Pro's voice assistant compatibility. The app also includes handy features, such as smart alerts, activity feed, and notifications. 

Finally, you don't have to worry about being locked out if the lock's batteries run out as you can always access the entrance with your keys.

What we liked
  • It is compatible with voice assistants.
  • It offers biometric verification for smartphone app access.

Another solid option in the retrofit lock arena

Buyers looking for smart locks that offer the best price-performance ratio won't do better than the Wyze Lock.

Top Features
  • It is compatible with almost all single-cylinder deadbolts.
  • It is Wi-Fi and Bluetooth enabled.
  • It offers a minimalist design.

The Wyze Smart Lock offers all the same features as the August Smart Pro Lock. The device is equipped with the Wyze Lock Gateway that acts as a bridge between the locking mechanism and your Wi-Fi connection. 

Installation & Smart Assistant Compatibility

Once your Wyze smart lock is installed and has access to the internet, you can explore the product's added features with the Wyze app and unlock voice assistant compatibility. The Wyze lock can easily pair with Amazon Alexa and Google Assistant. 

Since the Wyze lock is also of the retrofit variation, installation works the same as with the August Smart Lock Pro. You will not face any changes to the exterior of your door and be able to access your entrance with your existing keys. 

Mobile App

Now, let's talk about the advantages you can gain from the Wyze app. To begin with, the biggest benefit is remote access – you will be able to control the lock no matter where you are. You can also share app access with family and friends to ensure they don't have to worry about being locked out. 

The Wyze app also offers a history feed, smart alerts, door position notifications (without an added sensor), and more. The Bluetooth connectivity allows users to lock and unlock the device without having to use the app, and there's also an auto-lock feature that will lock the entrance once you're inside. 

Keypad

Users looking to extend convenience can rely on the Wyze keypad (sold separately) for locking/unlocking purposes. This is useful in a large household where keeping track of access can be a headache. Instead, you can share a single passcode with family members to keep things simple.

What we liked
  • You have complete control through the Wyze app.
  • It has voice assistant compatibility.
  • It has a built-in gyroscope to read lock position.
What we didn't like
  • Some users have reported issues with the auto-unlock feature.
9.2
Smaller-sized but with all the right features

For users who want a compact smart lock that does not compromise the quality.

Top Features
  • It is easy to install and beginner-friendly.
  • It comes with the August smart app and voice assistant compatibility.
  • It has built-in Wi-Fi.

The August fourth-generation locks work just like the Smart Lock Pro in terms of installation. An easy installation that would take you, at most, 10 minutes, and without any alterations to the lock. Here's what's cool about the Wi-Fi Smart Lock – it has built-in Wi-Fi, so there's no need to worry about a separate hub. 

Smart Features & Connectivity

What we like best about this version of the August Smart Lock is that it offers several smart features. It offers remote access and extended user control via the August app. The app also includes handy specialties, such as auto-lock/unlock, door position sensor, activity feed, and smart alerts. 

You can use the app to grant temporary or permanent access to family and friends, depending on your preference. The August Wi-Fi Smart Lock is also voice assistant compatible and will work with Amazon Alexa, Google Assistant, and Samsung SmartThings. 

These locks are much smaller in size than their third-generation versions, so they will blend in quite well with their surroundings.

What we liked
  • It has smaller dimensions.
  • It offers biometric recognition for app access.
  • It can pair with the August Keypad.
What we didn't like
  • The app interface can take some time to get used to.

A basic retrofit smart lock with all the necessities

The Kevo Convert Smart Lock by Kwikset is ideal for buyers looking to try out smart locks without spending too much.

Top Features
  • It connects to existing deadbolts and requires no external door changes.
  • It offers internet and Wi-Fi connectivity.
  • It is compatible with Amazon Alexa.

A smart lock that's also making waves is the Kevo Convert Smart Lock by Kwikset. However, this retrofit option clocks in at number three on our list for a reason. 

Users should know the lock requires the Kevo Plus Connected Hub for internet connectivity and smart home compatibility. The downside is that the hub is sold separately, so the money you will end up spending altogether is close to the price of the Wyze Lock. 

The Kevo Convert is a retrofit smart lock, however, its compatibility range with single-cylinder deadbolts isn't as varied as the August and Wyze options. 

Kevo Convert

The Kevo Convert does offer extended user control via the Kevo app with features such as eKeys for family and friends, usage history, auto-locking/unlocking, and military-grade encryption to keep intruders out. 

Smart Integration

The device does offer voice command control, however, only with Amazon Alexa, which may be a drawback for some. Buyers who rely on voice assistants such as Google Assistant may feel left out by not being able to take advantage of the voice command feature. 

On the other hand, the Kevo Convert Smart Lock is compatible with Apple Watches, Honeywell Thermostats, and Ring Doorbells.

What we liked
  • The Kevo app offers multiple features including auto-locking, usage history, and more.
  • It offers military-grade encryption for added security.
  • It comes with eKeys to share access with family and friends.
What we didn't like
  • The Kevo Plus Connected Hub is sold separately.
  • Some users have complained about the lagging issues in the mobile app.

An invisible smart lock

The Bolt Level lock is perfect for users who would like to keep the existence of their smart locks a secret.

Top Features
  • It has Bluetooth connectivity.
  • It is compatible with Apple HomeKit and Amazon Alexa.
  • It is designed to fit inside a door completely.

Adding a smart lock is one thing, but installing a smart lock that's invisible – that's another ball game. 

Buyers who want to secure the front entrance of their vacation home or rental property can rely on the Bolt Level Smart Lock. This device is designed to be undetectable after installation. 

Compatibility

The Bolt Level Smart Lock is designed to work with American-standard deadbolt locks. The lock has two parts: the center, which connects to the deadbolt, and the bolt. 

Installation

Installation can be tricky as it requires you to remove the deadbolt and the plates on the door jamb and door. Then, you have to enclose the center of the lock and the bolt inside the door cutout and ensure everything aligns with the deadbolt before screwing everything shut. 

Hardware Requirements

However, you will have to ensure your door meets the following specs before you set out to buy the Bolt Level Lock:

  • Door thickness – 1 ¾” thick
  • Borehole size – 2 ⅛” in diameter
  • Backset length – 2 ⅜” or 2 ¾”

Remote Connectivity

The device has Bluetooth connectivity and is compatible with Apple HomeKit and Amazon Alexa via the app. It also offers features such as auto-locking, creating guest passes, and usage history. 

What we liked
  • Remote control via HomeKit Hub.
  • It can be locked/unlocked with the app.
  • It is constructed from 6-gauge stainless steel.
What we didn't like
  • It is not compatible with Google Assistant.

The Verdict

Retrofit smart locks are an easy way to upgrade your front-door security without the hassle of changing locks and altering keys. You should pick the one that is best equipped to suit your needs.
