"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."

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

It’s best to avoid using oil-based lubricants within a lock because they attract larger amounts of dust and debris. When this occurs, it can make it harder for you to operate the lock, or it can even cause damage to the internal locking mechanism. A dry lubricant is the ideal solution instead.

There is a reason many commercial garages and storage facilities have roller garage doors. They stand out as one of the most secure options due to their unique design. The compact installation and absence of visible leverage points on the sturdy aluminum curtain make them a formidable obstacle for potential intruders. 

Smart door locks are safe to use and are usually considered safer than traditional locks with keys. While all electronic devices can be hacked, that doesn’t happen nearly as frequently in real life as people may think. You can also invest in multiple locks of different types for enhanced security so you don’t rely solely on one smart lock.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

You might assume that having two locks on one door will offer more protection than only one lock, but there may not be an advantage. While there’s nothing wrong with having two locks if you feel it’s best for your living situation, rest assured having one high-quality deadbolt installed correctly will offer a high level of protection.
