"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."

"ADT is the best company 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."

"I had a bit of trouble with my molding around the doors vs how the system was designed. The tech guy hung with me for 39 minutes until it was perfect. I called customer service a couple times after that with questions that came up. The customer service team are professional and knowledgeable."

"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.

"Mike and Crystal were very professional from the first phone contact through the completion of the work. They showed up on time, their work was neat and they worked very efficiently. My windows were in pretty bad shape. They really took their time and prepped them very well which showed in the finished product. When asked to redo or touch up anything it was done without question. In the end we received a very good paint job on a timely basis and at a competitive price. I have already recommended Mike's Painting to others in my neighborhood and would use him again for future painting needs.

"There were many things wrong in my computer (my fault and letting grandchildren on computer) Robert was so helpful, gave me many good instructions to keep everything safe, which I have written down, feel like I have a new computer. He was so excellent and experienced, took his time and was meticulous about what needed to be done. He was a pleasure to work with and I will use this company again! Linda Disy"

Locksmiths FAQs, answered by experts

The cost-effectiveness of fixing or replacing a door lock depends on the severity of the issue. Repairing a minor problem, such as loose screws or a need for lubrication, is usually cheaper than replacing the entire lock. However, replacing the lock if it is severely damaged, outdated, or lacks security features may be a better long-term investment. New locks often have improved security features, enhancing your property's safety.

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.

Using a combination of tools (often store-bought plumbing tools) and brute force, a burglar can easily snap the lock on a door. Snapping a lock aims to gain access to the cylinder inside, which holds the locking mechanism. Once the thief snaps the lock, they can pick the cylinder open and walk right in.

Rekeying should be done when employees leave or keys are lost, while replacement may be necessary for outdated or damaged locks.

Door locks should be changed roughly every seven years. The average lifespan of a door lock is seven to 10 years, so it’s best to err on the side of caution and change them early, especially if they are showing signs of wear and tear. Examples of deterioration include visible rust and difficulty opening or closing the door. Some locks can work safely beyond 10 years, but it depends on how often they are used and whether they are exposed to damaging environmental conditions like precipitation or extreme temperatures.
