Types Of Home Locks And Their Repair Methods
Jun 08, 2023
Securing your home is of utmost importance in today’s world, and a significant part of that security comes from the locks you choose. For this, it is vital to know the various types of home locks available, their unique features, and the repair methods used when they malfunction. Whether you’re a homeowner looking to upgrade your security or you’re stuck with a broken lock, this guide will equip you with all the necessary knowledge to make informed decisions.
This article delves deep into the various types of home locks and their repair methods.
Deadbolt locks stand as a testament to modern home security. Predominantly found in residential properties, these locks are designed with a unique mechanism that sets them apart from their counterparts. Unlike spring bolt locks, which can be easily retracted by applying force to the bolt itself, deadbolts require the actual key to open. This design ensures a higher resistance against forced entry techniques such as picking, bumping, or using a shim.
While deadbolt locks are renowned for their security, they are not immune to issues. Here are some common reasons they might fail or malfunction:
Misalignment: Over time, the door or frame may warp due to weather changes, causing the bolt not to align properly with the hole in the door frame.
Wear And Tear: Continuous use can lead to the wearing out of the internal mechanism, making the lock stiff or unresponsive.
Frozen Mechanism: In colder climates, the internal parts of the lock can freeze, preventing the bolt from moving.
Dirt And Debris: Accumulation of dirt and debris inside the lock can obstruct the smooth movement of the bolt.
Broken Key: Instances where a key breaks off inside the lock can render it inoperable.
Addressing issues with your deadbolt lock promptly can ensure the continued security of your home. Here’s a detailed guide on how to repair common problems:
Check The Alignment:
Use a straight edge or level to check if the door and frame are aligned.
If misaligned, adjust the door hinges or consider using a file to enlarge the hole in the door frame slightly.
Lubricate The Mechanism:
Before applying lubricant, ensure the lock is free from dirt and debris. Use compressed air to blow out any obstructions.
Apply a graphite-based lubricant to the keyhole and bolt mechanism. Avoid oil-based lubricants as they can attract more dirt.
Replace Damaged Parts:
Disassemble the lock to inspect for worn-out or damaged parts.
Replace any components that show signs of wear. It’s often more cost-effective to replace specific parts rather than the entire lock.
Addressing A Frozen Lock:
Use a hairdryer or a specialized lock de-icer to warm the lock. Avoid using open flames as they can damage the lock or door.
Extracting A Broken Key:
Use needle-nose pliers or a broken key extractor tool to carefully remove the broken piece from the lock.
If unsuccessful, consider calling a professional locksmith to avoid further damage.
Knob locks, a staple in many homes, are characterized by their door-opening mechanism: a turnable knob. Typically found on exterior doors, they often work in tandem with deadbolts to provide an added layer of security. Their design is both functional and aesthetically pleasing, making them a popular choice among homeowners.
Knob locks, while reliable, can encounter several issues over time:
Loose Knob: Continuous use, coupled with time, can lead to the knob becoming loose, making it difficult to turn or potentially causing it to fall off.
Jammed Mechanism: Dirt, debris, or a misaligned latch can cause the knob lock to jam.
Worn Out Internal Components: The internal components can wear out or break, leading to the lock becoming non-functional.
Key Issues: The key may not turn, may get stuck, or even break inside the lock.
Addressing knob lock issues ensures the security and functionality of your door. Here’s how to tackle common problems:
Tighten the Set Screw:
Locate the set screw on the neck or base of the knob.
Using a screwdriver, turn the screw clockwise until snug. Avoid over-tightening to prevent stripping the screw.

We have addressed some of the most commonly asked queries to provide you with a better understanding of the types of home locks and their repair methods.
Lever handle locks feature an ergonomic horizontal handle design, which requires a simple downward push to disengage the latch. This intuitive mechanism eliminates the need to grip and turn, making it especially beneficial for individuals with disabilities, arthritis, or any condition that affects hand strength and dexterity.
In commercial settings with high foot traffic, it’s recommended to inspect and maintain lever handle locks every 3-6 months. This proactive approach ensures optimal performance and longevity. For areas with less frequent use, a thorough annual inspection and maintenance routine should be sufficient to keep the lock in prime condition.
While lever handle locks are predominantly designed for interior doors, there are specialized models built for exterior use. These exterior models come with enhanced security features to withstand external threats. However, always ensure the chosen lock is rated for exterior use to guarantee durability and security.
A stiff or unresponsive lever handle lock often indicates a need for lubrication or cleaning. Applying a graphite-based lubricant can restore smooth operation. If lubrication doesn’t resolve the issue, it’s possible that dirt, debris, or internal wear is the culprit, and a more thorough examination or professional consultation might be necessary.
Lever handle locks provide a level of security that’s on par with many traditional locks. Their primary advantage lies in accessibility and ease of use. For areas demanding heightened security, it’s advisable to use lever handle locks in tandem with other security measures, such as deadbolts or electronic access systems.
Many lever handle locks are designed with user-friendly installation processes, making them suitable for DIY installations. However, to ensure the lock is fitted correctly, aligned properly, and offers maximum security, it might be beneficial to enlist the expertise of a professional locksmith or installer.
While there are various types of home locks and their repair methods, each with its unique features and benefits, regular maintenance and timely repairs can ensure they function effectively for a long time. Always consult with a professional locksmith if you’re unsure about the repair process or if the lock is severely damaged.
