We were looking for someone reliable to implement a master key system for our small office, and Los Angeles Lock & Safe offer was exactly what we needed, Ethan was our technician, he built a clear and secure key plan, he included Mul-T-Lock cylinders, and designed it that every team member now has the right level of access, the entire process was completed faster than expected, and the consideration for our working hours was above and beyond, we are so happy and satisfied with both the great results and the highly reasonable cost, thank you so much Los Angeles Lock & Safe.
