I had arrived at work this morning and found out that my employee had his key broke off inside the lock, to be honest it wasn’t his fault because that lock was jamming for quite some time. I called several companies at 8am. but only Jack San Francisco Door and Lock was able to show up after 15mins. He was very friendly managed to drill the lock and open the door in less than couple of minutes. He installed the new lock and gave us 5 extra keys. Great pricing and very professional service, definitely recommended!
