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. 

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.

Most jobs take 30 minutes to 2 hours, but high-security systems or multiple lock installations may require additional time.

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

Locksmiths typically recommend using a dry lubricant, such as a Teflon-based option, instead of the popular oil-based lubricants you can purchase at almost any store. Dry lubricants leave a non-stick, water-repellent coating instead of attracting more dirt and debris like an oil-based lubricant. You can find these at a hardware store; some are made explicitly for lock use.
