"This is the second time we used John. Since he was so good on our first project, it was an easy choice to call him again. This project was to replace rotted wood posts and railings on our front porch. As usual, John’s work was excellent. His attention to detail clearly separated him from many other contractors. John is easy to work with, does what he says he will do, communicated well, consults with you on any decisions and handles unexpected issues with ease. We will use John again for sure."

"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."

"Torin and Jack were so easy to work with, and they did an excellent job with our basement. It?s clear that Torin is very passionate about his company and the work that they do. We had to re-finish our basement after a pipe burst, and Torin made it easy to meet the requirements of our insurance agency. He provided all of the paperwork we needed in a timely manner, and was able to recreate our previous setup to the satisfaction of the insurance company. We also appreciated Torin and Jack?s flexibility with our schedule. They were very communicative and always let us know when they had openings ahead of our scheduled sessions so that we could continue to make progress on the build. We felt very comfortable with them in our home so often had them come while we were at work. Torin was very easy to work with and we highly recommend his company and will be using them again for future projects. Bonus - Torin and Jack both like dogs, and were super sweet to our pup! She loved having them"

Locksmiths FAQs, answered by experts

Newer, electric-powered door locks generally have a life span of five years or less. That’s thanks, in large part, to a phenomenon called planned obsolescence, in which products are programmed to need replacing after a certain amount of time. That’s also why older, manual, push-key locksets can last up to 30 years with regular cleanings and maintenance. When it does come time for a new set-up, know that the cost to change locks ranges from $130 to $500 on average.

In some cases this is possible, but it’s not advisable as the screwdriver is likely to leave marks all over the wall and a noticeable dent on the door. Move slowly and carefully if you have to use this method, and consider calling an emergency locksmith right away instead of trying to break in.

Deadbolts are solid and durable as can be, but the pin and tumbler can still be forced open, thus making this type of lock susceptible to picking. Most types of deadbolts are harder to pick than a traditional spring-based lock, though. It requires a specialized lock pick and a tension wrench to align all of the pins, thus unlocking the door. 

You might assume that having two locks on one door will offer more protection than only one lock, but there may not be an advantage. While there’s nothing wrong with having two locks if you feel it’s best for your living situation, rest assured having one high-quality deadbolt installed correctly will offer a high level of protection.

Smart door locks are safe to use and are usually considered safer than traditional locks with keys. While all electronic devices can be hacked, that doesn’t happen nearly as frequently in real life as people may think. You can also invest in multiple locks of different types for enhanced security so you don’t rely solely on one smart lock.
