Amazon Key works with Alexa
Enable the Amazon Key Alexa skill, and ask Alexa to lock or check the status of your door. Plus, you can enable “Unlock by Voice” in the Alexa App, which requires a 4-digit code when unlocking your smart lock.
You can also ask Alexa to show your front door on your Fire TV, Echo Show, or Echo Spot.
Multiple entry options
Lock and unlock by using the Amazon Key App, entering your pin code on the touchscreen, asking Amazon Alexa or with a physical key.
