This guide will help you enable unlock by voice for your Alexa-enabled smart lock. When users set up your new smart lock with the Amazon Echo they are initially only allowed to lock and to check the status of their device by saying:
"Alexa, lock my device"
"Alexa, is my device locked?" / "Alexa, is my device unlocked?"
However the command "Alexa, unlock my device" needs to be enabled separately.
Here are the steps to enable unlock by voice:
1) Go to the devices tab in the Alexa app, and tap on your smart lock
2) Tap on the settings icon in the top right corner
3) Tap on unlock by voice. Here you will need to enter a PIN code that Alexa will ask you every time you want to unlock your smart lock to verify you are authorized to do so. You will be prompted to confirm this decision by logging in to your Alexa account.
Now you are able to unlock your smart lock by linked to your Echo by saying:
"Alexa, unlock my device"
After this Alexa will prompt you for the PIN code you entered above. Once you tell her the correct pin your smart lock will unlock.
What to do if you don't have the Unlock by voice option in the Alexa app? Currently unlocking by voice is only available in a few countries so if the option is not available in your location you will not be able to use unlock by voice. It is worth checking every one in a while because there is a chance that Amazon will enable this feature for your location as well.
