I needed to rekey all the locks in my new home and San Francisco Door & Lock technician Mike immediately come in same day. He was professional and gave me a fair estimate and he went a few steps further. He offered a discount and explaining the all process for making the keys. After he toke care of the locks he allowed me time to test the locks and make sure the new keys working correctly. Mike was very helpful and answered all my questions with patience. The price was reasonable thank you very much Mike I had comfortable experience.
