"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.

"I would recommend them to a friend pending on their situation. If my friend need a locksmith right away, I would recommend C. D. Lock & Key, LCC. I did not hire C. D. Lock due to the price, and I wanted someone local that would not charge an expenses service charge."

Locksmiths questions, answered by experts

Yes, with better technology now available, it’s possible to add a smart lock on your sliding glass door. Smart locks can be easy for almost everyone in the family to operate and can connect to other safety features in the home, like smart lights. Plus, they’re harder for would-be criminals to pick. However, keep in mind that smart locks can potentially be hacked, and some completely rely on phones or Wi-Fi, which can be an issue if the power goes out.

There are several ways to add security to a sliding glass door. To start, install a rod or deadbolt lock instead of the flip-lock that comes standard with most sliding glass doors. Add a sensor to the door and monitor any activity through your home security system.

Finally, installing shatterproof window film will help keep the structural integrity of the glass if it cracks.

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.

You can cut a door knob off using a sawzall, but you risk causing additional damage to the door itself. You’ll also need to completely replace the door knob, costing you extra money and another trip to the hardware store.

Smart locks offer a similar level of safety to traditional or conventional locks because they often use comparable locking mechanisms, such as deadbolts. The primary difference is the access method: smart locks use a login or code instead of a physical key, which adds convenience. While not inherently safer, some smart locks have added security features that can deter intruders, like shutting down after too many incorrect code attempts or being harder to pick. For the best security, it's recommended to combine any lock with other home safety features like motion-activated lighting, security cameras, and window and door sensors.
