"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."

"Im am very happy I found this company! Thanks Nick and Marshal for the outstanding work. Their quality/detail is unbeatable! They went above and beyond to meet my expectations. They had a tough job to fix a deck that someone else built so poorly. They explained what could be done, what could improve but also what couldnâ t be fixed entirely. The only thing was that my budged was tight, but I also requested other things outside the quote he gave me. The only thing I would do different next time was to purchase all the items in advance and ask them to install. That would create less trips for them to the store prior to initiate the service/project. Thanks Nick and Marshal with everything. I hope to hire you next time."

Locksmiths FAQs, answered by experts

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.

When it comes to how to get a stuck key out of a lock, the simplest way is to use some kind of lubricating substance. One option is to apply graphite powder while wiggling the key gently. As the graphite fills the lock, jiggling should loosen the key enough to allow you to pull it out.

If you also have a standard door leading to your garage, install a robust deadbolt lock and reinforce the frame with security plates. Then, secure any windows with shatterproof glass or film to deter break-ins. Consider a smart garage door opener for your car entrance, enabling remote monitoring and control through your smartphone. Motion-activated lighting around the garage to deter intruders is a great way to amplify these security efforts. Lastly, educate your family on security practices, such as keeping the garage entrances closed and locked.

Commercial locksmith services range from $75 to $500, depending on the job's complexity, such as key duplication, lock installation, or access control system setup.

A deadbolt differs from a regular lock in its design, construction, and security level. Regular locks are typically used for interior doors, such as for bedrooms and bathrooms, and provide minimal security. They are easy to install and use, often featuring a simple locking mechanism on the inside. In contrast, a deadbolt is one of the most secure locks you can install on an exterior door. Its internal construction is designed to withstand significant force, adding a crucial layer of security that can deter intruders. While deadbolts may be more expensive and complicated to install, they are cost-effective for the security they provide and are built to hold up to wear and tear.
