"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"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."

Locksmiths questions, answered by experts

Rekeying door locks yourself costs a fraction of what you would expect to pay a locksmith. On average, it costs between $50 to $100 to hire a local locksmith to rekey your house, though labor costs may vary based on where you live. For a DIY solution, you can expect to spend $11 to $25 on a rekeying kit.

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.

Several types of deadbolts are available, including single-cylinder, double-cylinder, rim, smart, and electronic deadbolt locks. The most common type found in U.S. homes is the single-cylinder deadbolt, which uses a key on the exterior and a thumb turn on the interior. A double-cylinder deadbolt features two locking mechanisms and requires a key to be operated from both the inside and the outside.

The good news is that, yes, you can change locks yourself. Many people find it’s an easy DIY project that requires few tools and not much expense (depending on which lock you’re installing). If you have trouble with any part of an installation, you can always call a locksmith to help finish installing them.

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.
