How to connect locks to Alexa with SmartThings

With Amazon Alexa, SmartThings, and a connected lock, you can lock and unlock your door or check the current lock status, with just your voice! Here’s how to set up your locks with Alexa and SmartThings–from start to finish!


Getting Started

To get started you will need:

  • Amazon Alexa device (Echo, Tap, or Dot)
  • Samsung SmartThings Hub and app
  • A smart lock that works with SmartThings. Check out our supported locks here


1. Download your apps

  • Download the SmartThings mobile app for Android or iOS and create an account
  • Set up your Amazon Alexa device and download the Amazon Alexa mobile app for Android or iOS. You’ll use your usual Amazon account to login with this app


2. Connect your lock to the SmartThings Hub

  • For steps on connecting a Yale lock, see this article.
  • For steps on connecting a Kwikset lock, see this article for Z-Wave models and this article for ZigBee models.
  • For steps on connecting a Schlage lock, see this article for deadbolt models and this article for lever handle models.


3. Install the lock on your door

Follow the instructions in the installation manual that came with your lock.


4. Connect Alexa To SmartThings

In the Amazon Alexa app:

  1. Tap the menu (three horizontal lines in the top left)
  2. Tap Smart Home
  3. Scroll to Your Smart Home Skills
  4. Tap Enable Smart Home Skills
  5. Enter “SmartThings” in the search field
  6. Tap Enable for SmartThings / Samsung Connect
  7. Enter your SmartThings email and password
  8. Tap Log in
  9. Choose your SmartThings Location in the From: menu
  10. Tap Authorize
    Note: You can limit the devices Alexa accesses later in the SmartThings app
  11. Once authorized, the following message appears: “Alexa has been successfully linked with SmartThings.”
  12. Tap x to close the window and begin device discovery


5. Allow Alexa To Find Your Lock

In the previous steps, you gave Amazon Alexa permission to access your SmartThings devices and Automations. Now your Amazon Alexa device needs to “discover” or locate the devices and Automations.


In the Amazon Alexa app:

  1. After closing the success message in the previous steps, the Alexa app automatically directs you to discover devices
  2. Tap Discover Devices
  3. Wait for device discovery to complete

Note: Discover Devices will also discover your Routines.


If Alexa does not begin discovering devices:

  1. In the Amazon Alexa app, tap the menu
  2. Tap Smart Home
  3. Tap Devices
  4. Tap Add Device
  5. Wait for device discovery to complete


A progress bar appears in the Amazon Alexa app while Alexa looks for SmartThings devices and Automations you have authorized access to. This can take up to 20 seconds.

When discovery completes, discovered devices will list under Devices and Automations under Scenes in the Smart Home section of the Amazon Alexa app.

You can use the Alexa app to automate devices and Automations after discovery by tapping on the name or icon of the device or Automation. Automations will be displayed under the Scenes tab of the Smart Home section in the Amazon Alexa app.

Congratulations! You’re done with setup and ready to use Alexa’s hands-free voice control for your SmartThings devices!



Alexa can lock your doors and also tell you the status of your locks. Just give Alexa voice commands like the following examples:

“Alexa, lock the front door.”

“Alexa, unlock the front door.”

“Alexa, is the back door locked?”

When asking Alexa to lock or check lock status, you must use the name of your lock as it appears in your SmartThings app (i.e. “Front Door”).

At this time, Alexa does not support Routines with lock devices, and Groups with locks added to them in Alexa will not run.
