What Our Clients Say

  • "This company is tops in their customer service and standing behind their reputation. When I had trouble with keys they had cut for me, "Mitch" went the extra mile educating me on the subtle differences of the intended keys and the possible issues. He then provided me with a new cylinder to resolve the issue and included this per my original cost with no additional charges. Companies with high integrity are nice to come across these days!"

    Sean Dent

  • "We received great service from SLD. The technician was very knowledgeable, thorough, and patiently helped us with a large undertaking at our facility. Will use them again. :)"

    Saah Kelso

  • "SLD Security is a reliable company. Keith, our Service Coordinator, always ensures that our work orders are addressed as quickly as possible, and provides us with updates along the way. All technicians are professional and kind. They always make sure to walk us through what was done in order to solve the issue. We highly recommend SLD Locksmith."
