Not until X verb Y
X = he had arrived home
Y = he find he had left the key....
If we add a verb, then 'did' becomes ungrammatical:
It was not until he had arrived home did he find.... Ungrammatical
:D
By the way, the original sentence is not grammatical to me. I prefer:
Not until he had arrived home did he find he had left....

it's easy because you use did most of the time in questions! and as a past action! so did has nothing to do in the first one
