I believe the owner's name is Richard Guo. Speaks Cantonese, Mandarin, and English. When we called him in the morning, he asked us to email him a picture of our lock and he gave us a quote shortly thereafter. He said he could come in a few hours. He did end up being late, but said it was because a customer asked him to work on more locks than they initially asked him to do. He basically unscrewed the lock and took the unit to work in his car. Afterwards, he gave us three keys for the rekeyed lock. He worked quickly, didn't damage the lock, and stuck to his price of $40.
