"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."

"Front Door locks broken on my home. Had to take off work, no way to secure my home. Home Advisor put me touch with Colonial Lock Service, Inc. the gentleman on the phone tried to help trouble shoot the problem when that failed a locksmith was dispatched. The locksmith called and said I will be there in an hour. This young man showed up on time and said don't worry I hear to make it better. He had such great friendly personality and did a great job. He replaced both of my locks and said "Sir your new locks turn like butter now". Well that made my laugh but he was so right, my locks never worked so good. It appears when the door was replace 15 years ago the locks never really lined up right. The replacement locks were are not your local hardware style, much better quality. I was quoted a price which having never used a locksmith before I thought was high, however the quick response, great service, better then average hardware and most of all the locksmith had a great friendly attitude. The price was right. This young man shook my hand and thanked me. Right when I thought there was no more good customer service in this world, WOW!"

"Jeremy was punctual and professional. The appointment was easy to make with fast scheduling. I received an in-depth presentation and walk through of my home. He was very responsive to my questions and family's needs. There was no pressure to buy or add equipment I did not want or need. My new system was installed two days later. Larry the technical adviser was amazing. He was knowledgeable and friendly. He installed my system with no problems. He took the time to give us a lesson on how to use the app and new system. A few days later I had a question and he responded right away. I loved the system so much, that I referred my mother. Her system was installed a week later. I feel so protected knowing my family is safe using 1st Security Alarm company. I have the confidence of knowing that I can upgrade my system at any time. I can not thank Jeremy and Larry enough."

"I communicated with Rob Calbo for services of a background check with CSI Secure Solutions and he was fantastic.
He spoke with me in a very professional manner and put me at ease right away.
The process was seamless and my request was delivered very efficiently. Within just a few hours of providing them with information, I was able to get feedback. Rob took the time to speak with me and answered all of my questions. 
I will definitely be using them again in the future should the need arise, and I would definitely recommend them as being very efficient, professional and reliable.

Locksmiths FAQs, answered by experts

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.

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, many locksmiths offer 24/7 emergency services for business lockouts, broken keys, and security breaches.

Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.

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.
