"After a couple of unexpected incidents of vandalism in my neighborhood, I decided it is finally time to get serious about security. Angie's List led me to ADT; Fisher (last name) came over to my house the same day I called and walked through my entire place to give suggestions on the security system that best fit my needs. He is helpful and knowledgeable without a hint of pushy sales person. Fisher also secured a next day installation for me. The next day, Hector came to install, it was complex with a wifi camera and a bunch of sensors. Hector was polite, knowledgeable, super helpful and very neat in his installation. He provided a great demonstration and training on how to use the equipment and gave some great suggestions. I had some trouble with the camera the 1st night and I called Hector at 8:30pm, he trouble shoot my problem and resolved it in less than 30 minutes. Overall, a flawless experience. Fast, caring and professional - I would recommend them to anyone looking for a security system. To top it off, the pricing was very reasonable and there are always specials for installation. Two big thumbs up for Fisher and Hector!"

"I sent Art an email asking about his services.  He was extremely prompt in his response and I decided to schedule an appointment.  He was able to get me on his calendar quickly and performed an initial security assessment.  I had all kinds of ideas of what I wanted and I was impressed that Art had a solution for everything.  He's highly knowledgeable in the products and does not try to oversell you anything.
I'm technical and was interested in remote monitoring capabilities and home automation.  While I am technical, you definitely do not need to be to use this security system (or the home automation functionality)...it's all quite simple.  
Due to the nature of a security system, I cannot disclose details on the specific system or the cost.  I can say that it is thorough, complete, and exactly what I wanted.  The solution was customized to my exact needs based on what I wanted, not anything I was pushed towards.
Art is a man of integrity.  He's extremely professional and personable.  Security is not a t-shirt, so why chose a small-medium-large option like the other vendors?  Talk to Art and design the system that best fits your needs.  He will be able to address your questions and give you peace of mind.

"Frank is a really superb guy who's a gifted locksmith. And, furthermore, I really trust him. Let me be honest with you. I've always been anxious about hiring a locksmith. Frank, to me, had superb ratings on Angie's List. He engaged quickly during my quick call to him. We then communicated by text continually. He showed up in a quite impressive, branded commercial truck with all of the fixings! Great guy, very personable. He ably replaced the locks. Frank also checked out my other, external doors. He reinforced all lock plates with extremely long screws. I was impressed! I just wish I had more doors! (Just hire him!!)"

"Both times both technicians at Pocono locksmith were courteous prompt and professional they had comparable pricing and I have definitely recommended them to friends and neighbors if they needed anything in that area. They definitely offer a variety of services from the way it was explained to me on both occasions in case I ever needed any type of services in the future."

"I was accidentally locked out of my bathroom that morning.    
Everything went very well with M&D when I called for their help.  The customer rep who answered the telephone had great customer service skills.  M&D were quick to respond and they managed my expectations around the locksmith's time of arrival.  M&D sent a very competent worker named Daniel who assessed the situation and described all my options and prices before moving forward.  Of course, I would have liked the total price to be lower but the locksmith was so professional that I decided to replace other old/missing locks in the house as well.  
Daniel went back to the store, collected the additional door knobs and locks and returned to complete the rest of the job. He moved quickly and efficiently and was very pleasant to interact with.  In addition, he gave me quick tutorials on a couple of the new locks.  I was very pleased to have so much work done after having postponing the lock changes for so long.  M&D turned my bathroom lock-out accident into a positive experience!

Locksmiths FAQs, answered by experts

Rekeying your own locks is a low-cost task that prevents you from having to replace the locks themselves completely. The first couple of times you rekey a lock may be challenging because this is an intermediate DIY task. You can purchase a rekey kit from most hardware stores, but make sure you’re buying the kit from the brand of lock in your home that you’re going to rekey. 

If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position. 

But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

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.

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.
