"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

As with any computer, smart locks can be hacked by someone with the technical skills to do so, but most people do not have that ability, making smart locks relatively safe. If you have any concerns about a compromised smart lock, opt for an encrypted smart lock, change your Wi-Fi password, and make sure that you only give out your password to trusted family and friends.

Keyless locks are often considered safer since they’re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you’ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year.

One of the best tools for removing a stripped bolt is a handy pair of locking pliers. Locking pliers can usually grip onto screws with a broken, rounded, or stripped head and lock in place so that you can loosen even the most stubborn bolt that would otherwise remain hopelessly jammed.

When the temps drop, sometimes you need to thaw a lock to regain access. Options include warming the key with warm water, applying a de-icing spray, or using a hair dryer on low heat. Avoid using boiling water to prevent damage. To prevent future freezing, consider installing a cover or shield over the lock to keep water and ice out. Remember to be patient and gentle during thawing to avoid damaging the lock or key. If all else fails, consult a professional locksmith.

It could be difficult to get in and out of a lock for several reasons, such as the keyhole needing additional lubrication. Particles, debris, and dirt can also get into a lock, making a key stuck (the lubrication can help with the removal).
