Inquiry (采购产品): electronic lock Sirs: I am a 1-man business in a town of 9000 and service radious of 50 miles. My experience with "electronic" locks is the Weiser battery-powered push button entrance lock. I have a customer who wants a lock that will leave a trail. She will be using it as a stand alone single door lock. What is the best option that you offer?
