January 9, 2024

Welcome to our troubleshooting guide for rekeyed locks! We've all experienced the frustration of dealing with a malfunctioning lock at some point in our lives. Whether it's getting locked out of your house or struggling to turn the key, these issues can be incredibly annoying and time-consuming. But fear not! In this blog post, we will walk you through some common malfunctions that can occur in rekeyed locks and provide practical solutions to fix them. So grab your toolkit and get ready to become a lock-whisperer as we unravel the mysteries behind these pesky problems!


Rekeying a lock is the process of changing the internal pins and tumblers of a lock so that it can be operated with a new key. This is an effective way to ensure the security of your home or business, as it renders any old keys useless and prevents unauthorized access.


There are various reasons why you may need to rekey a lock – from moving into a new property to losing a key or simply wanting to upgrade your security measures. Whatever the reason may be, it's important to understand the basics of rekeyed locks in order to troubleshoot common malfunctions that may arise.  For enhanced security, consider having your locks rekeyed by our professional locksmiths.


How does Rekeying Work?


Rekeying involves disassembling the lock cylinder and replacing its existing pins and springs with new ones that correspond with a different key. This essentially changes the combination of the lock, making any previous keys ineffective. The new key will now be able to operate the lock without any issues.


A locksmith usually performs this process by using specialized tools such as pinning kits, plug followers, and master pins. However, if you have some DIY skills and access to these tools, you can also attempt rekeying your own locks at home.


Common Malfunctions in Rekeyed Locks

Rekeying a lock is a common practice for many homeowners and businesses, as it offers an affordable way to change the keys without having to replace the entire lock. However, like any mechanical device, rekeyed locks can experience malfunctions that may prevent them from functioning properly. In this section, we will discuss some of the most common malfunctions in rekeyed locks and how to troubleshoot and fix them.


1. Key Not Turning or Getting Stuck


One of the most frustrating malfunctions in a rekeyed lock is when the key does not turn smoothly or gets stuck. This can happen due to several reasons such as dirt or debris stuck inside the keyway, a damaged key, or misaligned pins inside the lock cylinder. To fix this issue, you can try using a lubricant such as graphite powder or WD-40 to clean out any debris from the keyway. If that doesn't work, try using a spare key to see if it turns smoothly. If neither of these solutions works, it might be best to call a professional locksmith for further assistance.


2. Difficulty Locking/Unlocking from Inside


Sometimes you may find that your rekeyed lock is difficult to operate from one side but works fine from the other side. This could be caused by loose screws on either side of the lockset or a misaligned latch bolt. Check all screws on both sides of the door and tighten them if necessary.

 

3. Key Jamming


It is a common issue that many people may experience with rekeyed locks. This occurs when the key gets stuck or refuses to turn in the lock, making it difficult or impossible to unlock or lock the door. It can be frustrating and inconvenient, especially if you are in a rush.


There are several reasons why key jamming may occur with a rekeyed lock. One possible reason is that there could be debris or dirt lodged inside the lock mechanism, preventing the key from moving smoothly. Another reason could be that the key itself is damaged or worn out, causing it to get stuck in the lock.


If you are experiencing key jamming with your rekeyed lock, here are some steps you can take to troubleshoot and fix the issue:


1. Clean and lubricate the lock: The first step to fixing a jammed key is to clean any debris or dirt that may have accumulated inside the lock mechanism. Use a dry cloth to wipe away any visible dirt, and then use a can of compressed air to blow out any remaining particles. Once cleaned, apply a small amount of graphite powder or silicone-based lubricant into the keyhole and on your key. This will help smooth out any rough edges on your key and make it easier for it to slide in and out of the lock.


2. Check for bent keys: If cleaning and lubricating do not resolve the issue, check your key for any signs of damage such as bends or twists. A bent or damaged key can easily get stuck in a lock. If you notice any deformities, it's best to replace the key to ensure smooth operation. Brothers Locksmith offers key replacement services, providing you with a new, well-functioning key tailored to your rekeyed lock.


  1. Assess the lock mechanism: Sometimes, the issue may lie within the lock itself. If the lock mechanism is faulty or worn out, it can contribute to key jamming. Brothers Locksmith's professional technicians are skilled in assessing and repairing lock mechanisms. Contact us for a thorough inspection to identify and resolve any internal issues causing key jamming.
  2. Professional Assistance: If all else fails, seeking the assistance of a professional locksmith is the most reliable solution. Brothers Locksmith specializes in rekeying services, ensuring precision and expertise in addressing key jamming issues. Our team can quickly assess the situation, identify the root cause, and implement effective solutions to restore the functionality of your rekeyed lock.


 4. Difficulty Turning the Key

Difficulty turning the key in a rekeyed lock can be frustrating and inconvenient, especially if it happens frequently. This issue can be caused by various factors such as worn out keys, damaged lock cylinders, or improper installation of the new key pins during the rekeying process.


If you are experiencing difficulty turning the key in your rekeyed lock, here are some steps you can take to troubleshoot and fix this common malfunction:


1.Check for debris or dirt in the keyway: Over time, dust and dirt can accumulate inside the keyway of a lock which can make it difficult to insert and turn the key. Use a small brush or compressed air to remove any debris that may be hindering smooth operation.


2.Lubricate the lock: Another common cause of difficulty in turning a key is lack of lubrication. If your lock feels stiff or resistant when trying to turn the key, adding some graphite powder or silicone-based lubricant can help improve its performance.


3.Inspect the condition of your keys: Keys that are bent, cracked, or excessively worn out can cause problems with turning them in a lock. Regularly check your keys for any signs of damage and consider getting new ones made if necessary.


4. Verify proper installation during rekeying: If you recently had your locks rekeyed by a professional locksmith, it's possible that an error was made during the process which could be causing difficulty with turning the key. Contact Brother's Locksmith and have them check their work to ensure that the key pins were properly installed and aligned. Brothers Locksmith takes pride in precision during the rekeying process, and our experts can swiftly identify and correct any issues related to improper installation.


  1. Examine the lock cylinder: The lock cylinder is a crucial component that plays a significant role in key turning. If the cylinder is damaged or worn out, it can impede the smooth operation of the lock. Brothers Locksmith offers thorough inspections of lock cylinders, and our skilled technicians can repair or replace damaged components to restore optimal functionality.
  2. Professional locksmith intervention: If the problem persists or you are unsure about identifying and addressing the issue, seeking the expertise of a professional locksmith is recommended. Brothers Locksmith specializes in diagnosing and resolving key turning difficulties in rekeyed locks. Our team is equipped with the knowledge and tools needed to tackle even the most complex lock issues, providing you with a swift and effective solution.


Key Doesn't Fit Properly:

If you have recently had your lock rekeyed and are experiencing difficulty with your key fitting properly, there could be a few potential causes. It is important to address this issue promptly as it can lead to further malfunctions or even prevent you from accessing your home or office.


Here are some steps to help troubleshoot and fix the problem of a key that doesn't fit properly in a rekeyed lock:


1. Check for Key Damage: The first thing to do is inspect the key for any visible signs of damage. This could include bends, breaks, or worn-down edges. If the key appears damaged, it may need to be replaced by a locksmith.


2.Clean the Key and Lock: Over time, dirt and debris can build up in both the key and lock, making it difficult for the key to slide smoothly into the lock cylinder. To clean them, use compressed air or a cotton swab dipped in rubbing alcohol to remove any buildup. Be sure to let both dry completely before attempting to use again.


3.Check for Pin Tumblers Misalignment: When a lock is rekeyed, new pins are inserted into the tumbler chambers according to the new key's pattern. However, if these pins are not aligned correctly with each other or with the corresponding cuts on your key, it can cause difficulty when trying to insert and turn the key. In this case, it is best to contact a professional locksmith who can realign the pin tumblers for you.


Lock Not Latching or Unlocking

One of the most frustrating issues that can occur with a rekeyed lock is when it won't latch or unlock properly. This can happen for a variety of reasons, but fortunately, there are some simple troubleshooting steps you can take to fix the problem.


1. Check the key: The first thing to do when your lock isn't latching or unlocking is to make sure you are using the correct key. If you have multiple keys for different locks, it's easy to get them mixed up. Also, check if there are any visible signs of damage on your key that could be preventing it from working properly.


2. Lubricate the lock: Over time, dirt and debris can build up inside a lock, causing it to become stiff and difficult to use. Try spraying a small amount of graphite powder or WD-40 into the keyhole and onto the key itself. This will help lubricate the internal components and may solve your latching or unlocking issue.


3.Adjust strike plate: The strike plate is the metal piece attached to the door frame that the latch hooks onto when you close the door. If this plate is misaligned or loose, it can prevent the latch from fitting properly into place. Use a screwdriver to adjust or tighten the screws holding in place.


4.Clean out debris: Sometimes, small pieces of debris such as dirt or lint can get caught in between the latch and strike plate, preventing them from connecting properly. Use a toothpick or small brush to remove any debris that may be obstructing the latch's movement. Ensure that the area around the strike plate is clear as well.

  1. Check for misalignment: Over time, doors and frames can shift, causing misalignment issues. Inspect the door and frame to see if they are properly aligned. If not, adjusting the hinges or seeking professional assistance to realign the door can resolve the latching problem.
  2. Examine the lock mechanism: If the lock mechanism itself is faulty, it can lead to latching or unlocking issues. Brothers Locksmith specializes in diagnosing and repairing lock mechanisms. Contact us for a comprehensive inspection to identify and address any internal problems affecting the proper functioning of your rekeyed lock.
  3. Professional locksmith assistance: If the troubleshooting steps mentioned above do not resolve the issue, it's time to seek the expertise of a professional locksmith. Brothers Locksmith has a team of skilled technicians who can quickly identify the root cause of the problem and implement effective solutions to ensure your rekeyed lock latches and unlocks smoothly.


Steps to Troubleshoot Malfunctions


When it comes to a rekeyed lock, it is important to know the proper steps to troubleshoot any malfunctions that may arise. Here are the key steps to follow in order to fix common malfunctions in a rekeyed lock:


1.Identify the Issue:The first step in troubleshooting a malfunctioning rekeyed lock is to identify the issue. This could be anything from a key not turning smoothly, difficulty inserting or removing the key, or a completely non-functional lock. Take note of all the symptoms and try to pinpoint what might be causing the problem.


2.Check for Obstructions: One of the most common reasons for a malfunctioning lock is an obstruction within the keyway. Before trying any other solutions, visually inspect your lock and key for any visible debris or foreign objects that could be preventing proper function.


3.Lubricate the Lock: If there are no visible obstructions, try lubricating your lock with graphite powder or silicone spray. This can help smooth out any rough spots and improve overall functionality.


4. Try Different Keys: In some cases, an ill-fitting or damaged key can cause issues with a rekeyed lock. If you have multiple keys for your lock, try using different ones and see if that makes a difference.


5.Use Key Extraction Tools: If your key is stuck in the lock or difficult to remove, consider using specialized tools such as broken key extractors or tweezers specifically designed for this purpose.

Locksmith’s Guide to Securing Sliding Windows

By Youmna Rehman • April 29, 2025
Sliding windows bring in light, fresh air, and a sleek aesthetic to any room. But they also bring a hidden risk—one that many homeowners overlook until it’s too late. Unlike standard windows, sliding windows often rely on simple latches for closure, making them an easy target for break-ins if not properly secured. As locksmiths know all too well, sliding windows can be a weak link in a home’s overall security. The good news? You don’t need to sacrifice ventilation or style for safety. With a few smart upgrades and a deeper understanding of how sliding window mechanisms work, you can protect your home from unwanted entry and keep your peace of mind intact. In this locksmith’s guide, we’ll take you through the vulnerabilities of sliding windows, how to address them step by step, the risks of ignoring the issue, and practical, expert-backed ways to secure your home for the long haul. How do door reinforcements work for added security? Why Sliding Windows Are Often Overlooked in Home Security Sliding windows are common in many homes, especially in kitchens, bathrooms, and ground-floor rooms. Their simplicity and ease of use make them a favorite for ventilation and visibility—but those same features can be exploited if the windows aren’t properly secured. Unlike casement or awning windows that lock into the frame with a mechanical arm, sliding windows typically use a latch mechanism that can be jimmied open with a bit of pressure or a tool. And because they don’t open outward, there’s less friction or resistance to stop an intruder from sliding the pane open quietly. The risk becomes even greater when windows are left slightly open for air. Without additional security measures in place, even a two-inch gap can be enough for someone to pry the window fully open from the outside. It’s a quiet entry point. A vulnerable one. But it doesn’t have to stay that way. Common Security Flaws in Sliding Windows There are several factors that contribute to the security weaknesses of sliding windows, and most stem from design limitations rather than user error. The most prevalent issue is flimsy locks. Many sliding window locks are built for convenience, not protection. They're often made of plastic or lightweight metal and can loosen or break over time. Worse, they can sometimes be forced open from the outside using nothing more than a screwdriver or coat hanger. Gaps in the track are another vulnerability. If the window slides too smoothly or the frame is slightly off alignment, it may not close as tightly as it should. These gaps give room for tools to wedge in and manipulate the latch from the outside. Then there’s the issue of false confidence. Many homeowners assume a locked window is a secure window, when in reality, most sliding window latches are more of a deterrent than a true barrier. To truly secure a sliding window, you need more than the factory-installed hardware. You need strategy—and the right upgrades. Step-by-Step: How to Secure Your Sliding Windows Step 1: Inspect the Lock and Frame Start by examining the condition of your current window locks. Open and close the window several times to test the latch. Does it stick? Does it click securely into place? If the lock feels loose or if the window can still move when it’s latched, it’s time for a change. Next, look at the track and frame. Make sure the window fits snugly into the frame and there aren’t any misalignments. An ill-fitting frame can make even the best locks ineffective. This initial inspection helps identify the baseline security level and any physical weaknesses that might need repair before enhancements are added. Step 2: Add a Window Pin Lock or Auxiliary Lock Standard latches are rarely enough. Installing a pin lock or an auxiliary locking mechanism gives your sliding window the kind of resistance that can deter forced entry. Pin locks work by drilling a small hole through both frames of the sliding pane and the stationary one. A metal pin or bolt is inserted through this hole, effectively locking the window in place and making it impossible to slide open without removing the pin from inside. Auxiliary locks, like double-bolt or keyed locks, attach to the frame and prevent sliding even if the latch fails. These are particularly effective for windows on the ground floor or those that face public walkways. Installation is usually quick, and a locksmith can do it professionally if you're not comfortable with drills and screws. Step 3: Install Window Security Bars or Rods Security bars aren’t just for high-crime areas. They’re a practical and visible deterrent for any sliding window—especially if you want to keep a window cracked open for airflow without sacrificing safety. You can place a removable metal rod or wooden dowel in the track behind the sliding pane. This physically blocks the window from opening beyond a certain point—even if the latch is broken or bypassed. Make sure the bar fits tightly in the track and can’t be lifted out easily. Adjustable bars are ideal because they allow you to tailor the opening depending on your needs. Step 4: Apply Window Sensors or Smart Alarms For those who like tech-driven solutions, consider adding smart sensors to your sliding windows. These small devices attach to the window frame and alert your phone or alarm system when the window is opened or tampered with. While sensors don’t physically block access, they offer the advantage of immediate awareness—especially if you’re away from home or asleep. Many systems are compatible with existing smart home hubs and can be easily installed with adhesive backing. When combined with physical security upgrades, alarms add a psychological barrier for would-be intruders. Step 5: Reinforce the Glass if Needed Even with a strong lock, the glass itself can be a weak spot. If you live in a high-risk area or just want added peace of mind, consider reinforcing the windowpane. You can use shatter-resistant security film, which holds broken glass in place even if it's smashed. This buys you time, creates noise, and discourages quick entry. For maximum protection, some homeowners opt for laminated or tempered safety glass, which is harder to break than standard panes. Risks of Ignoring Sliding Window Security Failing to secure sliding windows can have real consequences—financially and emotionally. Many home break-ins happen through unlocked or weakly secured windows, especially those at ground level or hidden from street view. And unlike doors, sliding windows can be opened with minimal sound or effort if the lock is compromised. An intruder can enter your home unnoticed, taking valuables, personal information, or worse. But it’s not just about theft. Weak windows also pose a safety risk for children and pets, especially if located on upper floors. A window that opens too easily can be dangerous for curious toddlers or adventurous pets. Securing sliding windows isn’t just about preventing crime—it’s about protecting everything you love. Challenges and What to Do About Them While securing a sliding window sounds simple in theory, homeowners often run into unexpected challenges along the way. One common issue is compatibility. Not all security bars, pin locks, or sensors fit every window type. Custom-sized windows or older models might need modifications or specialty hardware. If you're unsure about compatibility, a local locksmith can help assess your options and suggest the right tools. Another challenge is balancing ventilation and security. Many people like to keep sliding windows cracked open for fresh air, especially in mild weather. To maintain airflow without sacrificing safety, install adjustable locks or stoppers that allow limited opening but prevent full access. And finally, budget constraints can get in the way. Fortunately, many of the most effective sliding window security upgrades—like dowel rods, pin locks, or security film—are inexpensive and easy to install without professional help. The key is to start small and build your defenses one layer at a time. Expert Advice: Locksmith Tips for Long-Term Protection Seasoned locksmiths often recommend approaching window security in layers. It’s not about finding the one perfect lock—it’s about combining several methods to create a system that’s too time-consuming or noisy for any intruder to risk breaching. Consistency is also vital. Don’t secure just one window and leave the others vulnerable. If one window is easy to open, that’s the one a criminal will target. Experts also advise scheduling annual checks of your locks, tracks, and frames to make sure everything is still in working order. Weather changes and everyday use can loosen screws or warp materials over time, so a yearly inspection is a smart habit. If you’re unsure whether your sliding windows are truly secure, book a consultation with a local locksmith. A short visit could make a world of difference. Preventive Measures to Keep Your Windows Secure Once your windows are properly secured, it’s important to maintain that security. Keep all window locking mechanisms clean and lubricated to avoid jamming or corrosion. Regularly inspect the tracks for debris or warping. If you make renovations or move furniture near a window, recheck the locking devices afterward. Even a slightly shifted frame can throw off alignment and reduce security. And finally, teach all household members how the security measures work—especially children or elderly family members. A secure home only stays secure if everyone knows how to lock up properly. Conclusion: Don’t Let Sliding Windows Be Your Weakest Link Sliding windows don’t have to be a vulnerability. With the right combination of physical locks, smart sensors, and ongoing maintenance, they can be just as secure as any door in your home. It all starts with awareness. Once you understand how sliding windows are built—and where they fall short—you can take proactive steps to fortify them against intrusion. Security isn’t about living in fear. It’s about feeling confident, knowing you’ve done everything within your power to protect what matters most. So don’t wait for a break-in to take action. Secure your sliding windows today, and let the light in—without letting the danger in too.
