Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"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."

Award winning! Vintage Security provides monitoring services and security systems to over 19,000 customers throughout the Northern Virginia, Washington D.C, and Maryland areas. We offer a complete line of hardwired and wireless equipment to protect your home and/or business. Vintage Security skilled installers and technicians will treat your home and/or business as though it were their own.

"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."

Locksmiths questions, answered by experts

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

Rekeying should be done when employees leave or keys are lost, while replacement may be necessary for outdated or damaged locks.

Replacing your locks isn’t always a necessary option. You can usually save money by rekeying locks instead of replacing the hardware. You should consider rekeying the locks instead of replacing them in the following scenarios:

  • You want to upgrade your existing locks.

  • You have a lock you don’t want to replace.

  • You recently bought a home and want to change the locks.

  • You lost your key.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

It can affect security, especially if you don’t finish it properly. A Dutch door has more moving parts that can be compromised, so you’ll want to use solid hardware and make sure everything lines up and locks cleanly. If the latch is flimsy or the two halves don’t sit tight, it’s going to be easier to force open.
