Locksmiths questions, answered by experts

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.

A smart lock is a variation of a traditional lock, and since it uses similar locking mechanisms, it’s technically not any safer. The difference is that a smart lock requires a login instead of a physical key. Some smart locks have added safety features, like shutting down after too many attempts with the wrong code. Some smart locks are considered harder to pick than traditional locks, which can further deter intruders.

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.

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.

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.
