"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"My alarm installer Conner was very easy to work with. He was on the job site on time. He explained how the system work clearly. He took the time to hide all the wires and cleaned as he go. I'm happy with his installation. We highly recommend ADT Authorized Premier Provider to anyone that needs a new alarm or security system."

"Easy to make an appointment for a service call to have locks re-keyed. Technician arrived within given time, was extremely courteous and even fixed the bad installation of one lock. Forgot to mention Angie's list for a discount but will definitely use them again."

"GREAT PLACE!  Two years ago, a neighbor recommended Baldino's when I wanted to change the locks on my home.  Their Clarendon branch performed that service (promptly and with great customer service!).  
This time, I needed to unlock a pricey suitcase that I inadvertently locked while I was changing the lock's combination.  I called the manufacturer first.  They suggested that perhaps a locksmith could do it, sparing me the $75 it would cost me to ship it to them for repair.  So, I called Baldino's main line, explained the problem, and they recommeneded Chris at the Landmark location.  They said he was one of their most experienced locksmiths, and they were sure he could handle this. And he did!  Took him only a few minutes. Both Chris and the colleague he was working with at the shop (part time, retired Pentagon guy) were very polite, friendly, answered my questions and didn't make me feel silly for accidently locking the suitcase!  I'd go back anytime.  I'll be sure to use them for any future needs.

Locksmiths FAQs, answered by experts

As with any computer, smart locks can be hacked by someone with the technical skills to do so, but most people do not have that ability, making smart locks relatively safe. If you have any concerns about a compromised smart lock, opt for an encrypted smart lock, change your Wi-Fi password, and make sure that you only give out your password to trusted family and friends.

The good news is that, yes, you can change locks yourself. Many people find it’s an easy DIY project that requires few tools and not much expense (depending on which lock you’re installing). If you have trouble with any part of an installation, you can always call a locksmith to help finish installing them.

Whether or not keyless door locks are safe and trustworthy depends on the visibility of the programming code—and a trespasser’s determination. Even if you carefully guard entry and programming codes, those trying to break in may be able to crack open the lock’s faceplate with a screwdriver and change the codes. The same goes for manual models.

Some find smart locks the safest option because it’s harder to manipulate codes without access to your phone. But it’s possible to get hacked even then. Consider installing an extended security system, like door and window alarms or surveillance cameras, to enhance security. 

Proper door lock maintenance includes keeping the locking mechanism clean and clear of dirt, dust, and grime buildup, lubricating the lock annually, inspecting and tightening the lock regularly, and treating the door with care. If your maintenance reveals problems, it may be time to replace the lock or have a professional inspect it.

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.
