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: What is the best lubricant for a door lock?

• <div><p>It is best to use a dry lubricant, such as a Teflon-based option, for door locks. Unlike popular oil-based lubricants, dry lubricants leave a non-stick, water-repellent coating that does not attract dust, dirt, and other debris. Using an oil-based lubricant can cause these particles to build up inside the lock, making it difficult to operate or even damaging the internal mechanism. You can find dry lubricants, some of which are made specifically for locks, at most hardware stores.</p></div>

Q: How do you maintain a door lock?

• <div><p>Proper <a href="https://www.angi.com/articles/6-keys-proper-door-lock-maintenance.htm">door lock maintenance</a> includes keeping the locking mechanism clean and clear of dirt, dust, and grime buildup, lubricating the lock annually, inspecting and tightening the lock regularly, and treating the door with care. If your maintenance reveals problems, it may be time to replace the lock or have a professional inspect it.</p></div>

Q: How long does it take to copy a key?

• <div><p>When you take a key to a hardware store or a locksmith for copying, you can expect the key-cutting process to take as little as 30 seconds. The key copier will review your current key to decide on the correct blank. Then, your original key and the blank are inserted into a key duplication machine to cut an exact key copy.
