"Our dealings with Protect Your Home/ADT were delightful. We received a call back very fast after requesting a quote through Angie's List. We were able to complete everything on the phone; there was no paperwork or downtime. I had to call Customer Service with a question about the keypad, and they ended up telling me other helpful details on top of my original question."

"When I was locked out of my home I search on google for a local locksmith. Contacted Mr. Dominick from Safeguard locks, he is a very professional locksmith, punctual and charged me fairly. Before I decided to hire him I also contacted two other locksmith companies in Norwalk Ct but I decided to hire Mr. Dominick because his knowledge gave me confidence that he could do the job right. I was right, he was very respectful of my home, explain in details the job and the cost.. no surprises. If you live in Norwalk Connecticut or Fairfield County and you need a licensed locksmith for your home, car or truck look no further than Safeguard locks and ask for Mr. Dominick, he is truly the best locksmith I have ever worked with."

Locksmiths FAQs, answered by experts

Costs depend on lock type, service complexity, labor, emergency availability, and whether security system integration is needed.

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.

Smart deadbolts are a worthwhile investment for homeowners seeking more convenience, flexibility, and advanced features than a traditional deadbolt can provide. While a strong conventional deadbolt offers sufficient security for most, smart deadbolts provide significant upgrades.

Key benefits include keyless entry via smartphone, keypads, or biometric sensors, and the ability to lock or unlock your door remotely. You can also manage access for guests by creating temporary codes, eliminating the need for physical keys and the risk of them being lost or duplicated. Many models integrate with smart home systems and offer features like automatic locking, entry-exit monitoring, and tamper alerts with encryption for enhanced security.

However, there are downsides to consider. Smart deadbolts are more expensive than their traditional counterparts and rely on batteries and wireless networks to function. This dependency introduces potential vulnerabilities, such as hacking by skilled intruders and privacy concerns. Installation can also be more complex. Despite these drawbacks, the added layer of convenience and protection makes them a compelling option for many.

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.

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.
