Send message with code used on front door

I have a simple rule that will send me a text when a code is used on the front door. I cannot use Lock Manager as I have a Schlage lock that will not program with the app. What is the variable I can use to have it tell me "Front Door unlocked with Code Matt" vs just saying it was unlocked with Code?


%value% unlocked %device% at %time%'

This sends the following (as an example):

John unlocked Front Door Lock at 11:11am


thank you
