"Very well, the locksmith arrived n time and got to work right away in replacing the locking system. He then took the time to show me how to adjust the door in the future so it would not stick as the house moved. An absolute must if you need a locksmith."

I’m a reliable construction and maintenance professional with hands-on experience in residential repairs and renovations. I currently work as a maintenance technician for a large property, handling everything from small fixes like lighting and fixtures to larger projects such as laminate flooring, sinks, and vanities.\n\nPreviously, I was a project manager overseeing full kitchen and bathroom gut renovations, while also working hands-on from demo to installation. This gave me a strong understanding of doing jobs efficiently and to a high standard.\n\nI take pride in being detail-oriented and delivering quality results that last. I’m also honest and upfront—if something is outside my expertise, I’ll communicate that clearly. With strong customer service skills, I focus on making every job smooth, professional, and stress-free for the customer. \n\nIf you’re looking for someone reliable, hardworking, and committed to quality, I’m here to help get the job done right.\n\n

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.

Lubricating a door lock is an important part of door lock maintenance. It involves taking the lubricant of your choice (it’s best to use whatever the lock’s manufacturer suggests) and spraying it directly into the keyway. Push and pull your key in and out of the lock to make sure it’s all the way in. 

If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position. 

But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.

Keyless locks are often considered safer since they’re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you’ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year.

Regrettably, entirely pick-proof locks don't exist unless you opt for keyless varieties. Locks advertised as "pick-proof" are, in reality, more resilient against lock-picking and bumping attempts because of complex mechanisms consisting of pins and sidebars. These locks work like this—they assign two tasks to the key, enhancing security by making unauthorized entry more challenging.
