My son had lost his keys on its way back home from school while I was at work, I called San Francisco Door and Lock and their tech was at our place within 30 minutes. He got right to work and opened the door for my son not before we exchanged text massages and after he clearly identify me as the owner of the house, I’ve also asked him to cut 2 new key copies and he charged my card over the phone, excellent service highly recommended!
