I asked this before I think. It was driving me nuts why it wouldn't work but I realized because my office is maybe 200 yards from my home that this caused it not to activate. I'm thinking of setting my home address a block farther away from work so that it can start working but wondering if anyone knows the distance away it should start working? It seemed to be intermittent even almost a mile away. I'll experiment with various addresses farther down the street and see. It just occurred to me to try that since it's irritating I can't use the function and my car auto locks while in my garage as I walk around to the other side.
