Q: What should I do if my key breaks in the lock?

• <div><p>If your key breaks in a lock, first remain calm and avoid forcing the broken piece further in. You may be able to remove it yourself if a portion of the key is still protruding from the lock. To aid removal, lubricate the keyhole with a graphite-based spray. Then, try using tools like pliers, tweezers, a bobby pin, or even a jigsaw blade to gently grasp and pull the broken piece out. If these methods don't work, you can't reach the key, or you're concerned about damaging the lock, it's best to call a professional locksmith for assistance.</p></div>

Q: What is lock bumping?

• <div><p>Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most <a href="https://www.angi.com/articles/types-of-deadbolts.htm">types of deadbolts</a>. It involves inserting a specially crafted key, or bump key, into the lock and tapping or &quot;bumping&quot; it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.</p></div>

Q: Why is my lock not opening with the key?

• <div><p>First thing first: Make sure you&rsquo;re using the right key. If it&rsquo;s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you&rsquo;re still locked out, call in for help. </p></div>

Q: How often should door locks be replaced?

• <div><p>Door locks should be changed roughly every seven years. The average lifespan of a door lock is <b>seven to 10 years</b>, so it&rsquo;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.</p></div>

Q: How much does it cost to get a door lock service?

• <div><p>A door lock service is performed by a professional locksmith, and <a href="https://www.angi.com/articles/keys-home-locksmith-assistance-and-costs.htm">the cost of hiring a locksmith</a> for these kinds of repair tasks usually runs in the <b>$100 to $250 </b>range.

"Rodney and his assistant (his name escapes me) were awesome. When he initially came he found that the door and frame we'd already purchased weren't the right size for our door. He advised us what to buy and when it came in, he went the extra mile to pick it up for us, and he also made a trip to get a new piece of framework we needed. They were quick with the installation, fixed any issues that popped up and did a great job. I'd hire them again for sure."
