"Called on Rick Ennis to install double locks on my front and back doors. He came out to install locks under short notice and work was completed in a timely matter - at a very reasonable price. He also specializes in "Access Card" and "Key Control Systems". I'm extremely pleased with his service and will definitely call on him again."

"Citywide Roadside Lock and Key did an excellent job installing a new lock to our residential front door and provided three sets of keys for access. They were professionally, courteous., and knowledgeable.The house is an older property that belonged to our late grandfather and grandmother who passed on. The front door was very old. However, the Lock Smith asked for a picture of the lock, which I sent and he knew exactly what type of lock it was that needed to be replaced. Prompt in getting us scheduled to complete the job. I would highly recommend their services for all your lock and key needs."

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"I have been on this system for 3-4 years. The initial installation went ok, but the overall functionality and reliability of the system is poor. The basic alarm system works when you manually arm/ disarm it through the app or keypad. However, the alarm cannot be set up on an automated schedule, and NONE of the connected automation features work - lights, outlets, blinds, etc. I purchased the recommended products that the company promised would seamlessly integrate into the system during the sales pitch, but none of them work. They have sent technicians out a couple times but, even after installing bulky repeater boxes in about half a dozen outlets, the system cannot connect. I have submitted several tickets, but Vintage just closes them out and suggests that I self troubleshoot. Alternatively, I can pay for an Automation Maintenance package and they will send a technician out. Bottom line - their system is nothing more than a 1990's alarm with a keypad and phone app. They dont deliver on what they sell, and they try to charge extra for support that should be included."
