Ease of Use
Everyday usage and multiple users
This smart lock is actually fairly simple to use—there are no complicating bells and whistles on the lock itself, and the app is pretty straightforward, telling you exactly who locked or unlocked the door and when.
You can use the app to remotely lock/unlock when within Bluetooth range, or if using the optional wi-fi adapter, from anywhere.
Because this is a lock attachment that fits over your existing lock, you always have the option of using a physical key, so you’ll never have to worry about getting locked out.
A few users have reported that the Android version of the app isn’t receiving the same tech support as the iOS version of the app and therefore, has more issues.
For those reasons, we gave the Sesame smart lock an 8/10 in the ease of use category.
Smart Home System Integration
Which systems is this smart lock compatible with?
This smart lock works with IFTTT enabled devices and is also compatible with Google Home, and Amazon Alexa.
It can also be controlled via voice command through Siri.
However, be aware that an earlier version of this lock (which is still offered for sale online) only works with IFTTT devices. Make sure, if you’re wanting to use it with Google Home or Alexa that you purchase the latest version of this lock.
Because this smart lock is compatible with Google Smart Home, Alexa, and Siri, it gets an 8/10 here.
Ease of Installation
This smart lock fits over your existing deadbolt. All you have to do is pop the smart lock in place over the existing thumb turn and use the adhesive tape that comes with it to attach the lock to the door.
For door-handing, you either pop the lock on right-side-up or turn it upside down. Done.
It really doesn’t get any easier than this when it comes to smart lock installation!
Because this lock literally snaps into place over your existing thumb turn, and no tools are required, this lock gets a 10/10 on installation.
Robustness of the App
What the app can do and how easy it is to use
The Sesame smart lock app allows for true remote access if you purchase the optional wi-fi adapter. The app is free and works with both Android and iPhones.
With the app, you can add up to 99 users (and remove them), see the lock’s usage history, lock or unlock the door remotely, and see the lock’s status. You also have the ability to activate the auto-lock feature through the app.
Interestingly, if you’d rather control your lock through a laptop or PC instead of the mobile app, you can use the cloud to communicate with the Sesame smart lock. However, if the website goes down for any reason, you will lose access to your lock until it comes back up.
It has been reported that the app doesn’t function as well for Android users and that it isn’t being supported as well as the iOS app.
Because this app has all the standard features of other smart lock apps but doesn’t have the software update support or reliability for Android users that it does for iPhone users, the Sesame smart lock gets a 7.5/10 in this category.
How this smart lock opens the door
If you purchase the lock by itself, you can unlock the door remotely as long as you’re in Bluetooth range. If you purchase the additional wi-fi adapter, you can lock or unlock the door remotely from anywhere.
Since this smart lock attaches to your existing lock, you can also use a physical key to lock or unlock the door.
You can also knock on your phone’s screen (if you have an iPhone) to unlock the door.
While knocking on the phone is a novel idea, the Sesame smart lock’s options for getting in are limited compared to other smart locks and earns a 6.5/10 in this category.
$150; $70 for optional WiFi adapter
This lock retails for $150, and although it can be found far more cheaply online, be aware that the cheaper option is an earlier version of the lock that doesn’t work as well as the most recent (more expensive) smart lock.
The optional WiFi adapter costs an additional $70, for a total of $220 for both.
While this would be a great value if it were a full lock assembly, it’s a bit pricey for a lock attachment, when considering that some full lock assembly smart locks offer built-in wi-fi for only about $30 more and have additional features, such as touchpads.
It does offer integration with Alexa, Google Home, and IFTTT devices, an upgrade from the earlier version, which only allowed for IFTTT integration.
Balanced against the smart home device integration, this smart lock’s cheap-looking plastic cover and limited options, when compared to other smart locks, makes it below average in overall value.
Remote Connection Type
Wi-Fi, Bluetooth, or Both?
Without the optional wi-fi bridge, this lock uses Bluetooth to connect to your phone. If you purchase the additional adapter, you will also have wi-fi connectivity and true remote access to your lock.
Because you have the option of adding wi-fi and can use Bluetooth, we gave the Sesame smart lock a 7.5/10 here.
The Sesame smart lock uses two 3-volt lithium batteries. According to the manufacturer, these should last about 500 days (or roughly a year and four months) before needing to be replaced.
There’s a low battery warning in the app, but it has caused enough confusion to need a separate explanation page on the manufacturer’s website.
We balanced the cost of replacing the batteries against the frequency of replacement and the low-battery warning feature and gave this smart lock a 9/10 in this category.
Lock attachment or full lock?
This smart lock fits on top of your existing single deadbolt—it literally pops over the pre-existing thumb turn and covers the original lock on the inside of your door. But your current lock has to fit within certain dimensions (and certain thumb screw types) in order for it to work.
An adhesive strip attached to the back of the lock is what holds the lock in place on your door. This is the least secure method of attaching a lock we’ve seen and is probably not a good option for households with rambunctious children.
Since this is a lock attachment and not a full locking system, and because of the lock’s not-very-sturdy plastic covering and adhesive-only attachment, we gave the Sesame smart lock a 6/10 here.
Keys or Completely Keyless Entry?
Since this lock fits over your existing lock, you still have the option of using your key—it doesn’t replace your existing lock’s exterior.
Otherwise, you can lock and unlock the door remotely via the app or by knocking on your phone (iPhone users), and even through a laptop/PC via the cloud.
We gave this lock an 8/10 for offering both keyless and physical key entry methods.
This lock has a one-year limited warranty that covers defective materials or workmanship.
Other smart locks on the market, however, come with two- or three-year limited warranties on the electronic components and limited lifetime warranties on the finish and mechanical parts.
Because of the lackluster warranty, the Sesame smart lock earns itself a 6.5/10 here.
You have the ability to knock on your phone and unlock the door, but this option is only available for iPhone users at this time.
