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."

"Kevin was outstanding, I recommend this service to anybody needing lock or key services. I had lost my keys to my 1987 Bronco and Kevin was able to grain full access. I needed full service replacement of ignition and door locks and keys. He was able to do this quickly and for a good price. He actually made a house call bringing his mobile workshop to my job. Everything was taken care of from getting the parts at the parts store and installing it to get me working. Very professional and very reasonable. I highly recommend this service."

"Landmark Uses Disreputable Contractors ? AZA Repair & Brenovations HVAC Are the Worst Landmark sent AZA Repair for my refrigerator, and they left it worse than before?still not working, scorch marks from a blowtorch, copper lines sticking out, tools and oil left behind, and no receipt. Then Landmark sent Brenovations HVAC for an AC motor replacement, and that turned into exposed wires, bolts hitting fan blades, missing parts, and complete disregard for safety near my kids? play area. Both companies were unprofessional, negligent, and refused accountability. Landmark?s use of these contractors makes me seriously question the value of having a home warranty at all."

Locksmiths questions, answered by experts

In general, keyless door locks are considered safe. They can’t be picked like a traditional lock, and unless a thief can guess your code, it’s pretty tricky to break into a house with a keyless door lock. But that doesn’t mean they come without risk. 

When asking yourself, "Are keyless door locks safe?” consider the style of the system. Hackers could potentially break in if it operates on Wi-Fi, but it’d take some time and effort. You’re also at risk for a power outage, depending on the type of lock. That being said, there are no more risks associated with keyless door locks than a traditional lock.

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.

You might want to change a door lock entry code for a handful of reasons. The most common answers are extra security or a forgotten code. You may also find yourself in a position where you need to temporarily change the code to allow a guest to come and go freely but want to switch it back once things return to normal.

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

In some cases this is possible, but it’s not advisable as the screwdriver is likely to leave marks all over the wall and a noticeable dent on the door. Move slowly and carefully if you have to use this method, and consider calling an emergency locksmith right away instead of trying to break in.
