Most people don't think about the need for a quality locksmith until they need one. I'd say that Levi definitely passes the muster as far as competent professionals go; in addition to being punctual, expedient, and personable, the man's encyclopedic knowledge about keys and locks is impressive.
I'd like to say I walked away from the experience knowing there's more to keys than "stick the thing in the hole, turn it, and hope for the best", but having Levi's number in my phone insures that I won't have to (for better or for worse). In summation, this man is great at charming obstinate doors. The end.
