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."

Locksmiths questions, answered by experts

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

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.

Yes, keyless locks can be quite safe, but their security depends on the type and quality of the lock you choose. Many keyless locks offer added features like biometric access, PIN codes, and smartphone connectivity, making them potentially more secure than traditional locks. However, keyless locks can also be susceptible to hacking, battery failure, or technical malfunctions, so it's important to choose a reliable brand and stay on top of software updates and maintenance.

Yes. Most deadbolts purchased from a home improvement store include a step-by-step installation template that is easy to follow, even for novice DIYers. One of the most important steps for successful deadbolt installation is having the proper tools to start with and carefully measuring prior to any attempts at installation.

Many insurance providers offer policy discounts when adding security features to your home. The best way to find out if new locks will reduce your premium is to simply ask your agent.
