"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

"The locksmith was here at the front end of the window.  I bought my own locks so there was no need to make new keys.  The locksmith provided exceptional service -- will definitely use again if I have a need.

"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

Changing door locks is a task that most homeowners can accomplish on their own. Standard door knobs are quite straightforward, and even more advanced locks, like electronic or smart locks, generally come with instructions. That said, the process can be time-consuming, especially if you plan to replace multiple locks around the house. It’s also a task that you want to complete correctly, considering that it affects the security of your house. That’s why hiring a pro is often best when changing your door locks.

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.

It depends on what type of keyless entry it is and if the locksmith has the proper tools to remove a keypad entry lock since some are more advanced than others. However, locksmiths can typically work around keyless entries to vehicles, so it depends on what type of keyless entry system needs opening.

Regrettably, entirely pick-proof locks don't exist unless you opt for keyless varieties. Locks advertised as "pick-proof" are, in reality, more resilient against lock-picking and bumping attempts because of complex mechanisms consisting of pins and sidebars. These locks work like this—they assign two tasks to the key, enhancing security by making unauthorized entry more challenging.

If your key breaks in a lock, first remain calm and avoid forcing the broken piece further in. You may be able to remove it yourself if a portion of the key is still protruding from the lock. To aid removal, lubricate the keyhole with a graphite-based spray. Then, try using tools like pliers, tweezers, a bobby pin, or even a jigsaw blade to gently grasp and pull the broken piece out. If these methods don't work, you can't reach the key, or you're concerned about damaging the lock, it's best to call a professional locksmith for assistance.
