Locksmiths questions, answered by experts

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.

Rekeying a lock is less expensive than replacing the whole unit. The cost to rekey is about $50 to $100 when you hire a pro or as little as $10 if you DIY. The cost to change a lock is $130 to $500, depending on the hardware you select.

Using a combination of tools (often store-bought plumbing tools) and brute force, a burglar can easily snap the lock on a door. Snapping a lock aims to gain access to the cylinder inside, which holds the locking mechanism. Once the thief snaps the lock, they can pick the cylinder open and walk right in.

It depends on what type of keyless entry it is and if the locksmith has the proper tools to remove a keypad entry lock since some are more advanced than others. However, locksmiths can typically work around keyless entries to vehicles, so it depends on what type of keyless entry system needs opening.

A deadbolt has a different design, construction, and security level than a regular lock. Regular locks are mostly used for interior doors around the home, like bedrooms and bathrooms, and they usually include a locking mechanism on the inside. While regular locks are easy to use and install, they provide little security. 

A deadbolt adds a layer of security and is most commonly used on exterior doors. The installation is typically more complicated, but they hold up to wear and tear.
