Sesame Smart Lock Ratings

From its humble beginnings in a dorm room, to securing homes across America Sesame has risen as a contender in the smart lock arena. These budget-friendly locks fit over existing deadbolts, so they are ideal for renters and the DIY crowd. Sesame offers integration into many smart home ecosystems, and delivers tech-forward features like remote access and a ‘knock to open’ function. However, the hardware options are limited. See what our experts say in our Sesame review.

  • Affordably priced
  • Wide range of integration with home automation systems
  • Keyless smart lock
  • Fits over existing deadbolt

  • Limited hardware options
  • Newer player on the market


Candy House got its start when Jerming Gu became focused on minimizing the objects in his pockets. That motivation lead to a desire to end the need to carry anything but a smartphone around, replacing his keys. He started working on something that would work on his university dorm room lock, which meant a choice that simply fits over the existing deadbolt rather than replaces it. One of his wife’s friends turned out to be an excellent software engineer, and he supplied the software for this smart lock robot. They named it Sesame, after the phrase “Open Sesame.” In 2015, they received $1.4 million in Kickstarter funding to manufacture this device.

Features & Technology

Retrofitted Smart Lock

Unlike other smart lock products, Sesame doesn’t replace your deadbolt. It fits right over it. The motor in the device turns the knob and lock. Due to this configuration, it’s compatible with a wide range of deadbolts worldwide.

Generate Guest Keys

Make it easy for friends and family to come and go by assigning them guest keys. You can have 99 guests.

Automate Locking and Unlocking

If you don’t want to worry about that entire process, you can program the Sesame to lock and unlock based on specific conditions.

Remote Access

The Wi-Fi access point makes it possible to control Sesame from any location.

Real-Time Notifications

Find out when people are visiting and other valuable information.

Smart Home Automation Integration

Sesame is compatible with Nest, Samsung SmartThings, IFTTT, Homekit, Amazon Alexa, Z-Wave and Zigbee devices.

Public API

Sesame invites developers to create other integrations through its API. They’re happy to help you even if you don’t know anything about programming.

Strong Encryption

Sesame uses AES 256-bit encryption with TSL 1.2. The company understands that cybercriminals look for ways to hack all types of devices, not just computers. They have protocols that defend against man-in-the-middle and relay attacks. The lock only unlocks when the right credentials get presented to it.

Knock to Open

If you have an iOS mobile device, you don’t even need to pull out your phone to open the door. Instead, knock on it to activate the smart lock.

Keyed Backup

In an emergency, you can still use your original key as a backup.

Voice Control

Google Assistant, Amazon Alexa, Apple HomeKit and Siri are supported (or soon to be supported) by Sesame.

Home Automation Potential

Sesame is designed for seamless integration with other products and services. IFTTT alone gives you links to 400 services. It also features auto-replenishment of the device’s batteries via Amazon.

Flexible Notifications

You not only get notifications through the Sesame app about activity, but also through social media platforms.

Sesame can let you know through its own app or through social media platforms like Facebook, WeChat, and LINE.

500-Day Battery Life

This device uses 2 CR123A batteries and has a maximum battery life of 500 days.

Delegate Guest Management

You don’t have to be the only one managing guests. You can choose a manager among your friends and family. They can add and remove guests.

Ease of Use

Everything from the installation to the third-party integration is designed with a user-friendly experience in mind. You shouldn’t run into any problems even if you’re a smart home automation or smart lock newbie.

Customer Service

You have several customer service options available and the representatives are knowledgeable in the product since that’s all the company offers, rather than working in multiple markets. You can send an email, check-in on the community forum, or look through the documentation to get help with your product.


Sesame has a great price point compared to other smart locks on the market and it doesn’t skimp on the features. You don’t get as many finish options as other companies offer, so that could throw off your design a bit. However, that’s a small thing to worry about when you consider how well it integrates with the rest of your smart home ecosystem. You don’t need to buy any ongoing subscriptions to use this product.


Candy House has a streamlined product choice. The Sesame smart lock ($149.99) is designed to fit into a single turn deadbolt without needing an extensive installation process. It also works with a doorknob that doesn’t have a base if it matches the size of the Sesame. Since you don’t have to take your deadbolt apart for the installation, this is an excellent choice for renters.

This modern smart lock comes in four finishes to mesh with your existing exterior style. You lock and unlock your home through the Sesame app. Automated locking and unlocking create a streamlined and safe experience. One quirky feature is the ability to unlock the door by knocking on your phone with the app up.

Some Sesame smart lock features need the Wi-Fi Access Point (69.99) device. For example, unlocking your front door remotely outside of Bluetooth range requires this piece of equipment, as well as managing your guest list over the Internet. If you want to use Google Assistant, Amazon Alexa, IFTTT or the API, you need the access point. The Wi-Fi Access Point uses a USB interface, so it’s easy to connect anywhere in your home.


Sesame takes an innovative approach to smart locks and the result is a versatile product that gives you a lot of flexibility for a smart home. It really thrives in an environment where you have home automation services and equipment working in tandem to create a pleasant and welcome home at all times, without a lot in the way of manual input.
