One of our filing cabinet in the main office had a missing key and we needed its lock changed, Amir from Chicago Safe & Lock was very professional and asked for some photos of the filing cabinet and the lock before he came, and after we sent him the photos he quickly estimated the job and his time of arrival. Amir showed up right on time, with the right lock replacement, quickly drilled the old lock and installed the new one instead, we were really impressed by how quickly he fixed the issue and would be more than happy to recommend him.
