My teenage daughter lost her key at school, and I had to find a locksmith fast, I called few places and San Francisco Door & Lock had the fastest respond, Sammy the locksmith technician got back to me right away, and made me feel very calm and safe about him coming over, he arrived promptly and the entire service was on video cam, he quickly unlocked the door and handled the payment over the phone, very professional and totally reliable service, highly recommend them and full of appreciation!
