Locksmiths questions, answered by experts

Rekeying your own locks is a low-cost task that prevents you from having to replace the locks themselves completely. The first couple of times you rekey a lock may be challenging because this is an intermediate DIY task. You can purchase a rekey kit from most hardware stores, but make sure you’re buying the kit from the brand of lock in your home that you’re going to rekey. 

You should replace door locks when you move into a new home since you don’t know who has copies of the key. Other reasons to change your locks include an attempted break-in, when someone moves out of your home, or if you lose a key with an address attached to it.

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

Proper door lock maintenance 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.

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.
