Security is important to all businesses – from large corporations to locally owned mom-and-pop stores. Business owners have many responsibilities, security being a major concern for all. Businesses throughout the country benefit greatly from key control, a popular method of maintaining more control over your commercial property. Key control is essentially a system of tracking which employees have keys and what areas they have access to with those keys.
What is Key Control and Why Should My Business Care?
March 6, 2023
Employees account for over 40% of occupational fraud and $3.7 trillion in lost revenue each year for all businesses, according to the 2014 Global Fraud Report. Much of this fraud and lost revenue occurs because keys are issued to employees and never returned when the employees leave the company.
A key control system is critical to not only the security of a facility, personnel and equipment, but can also save you money. Key control, which ensures that certain keys are only used by authorized people, involves strategies for keeping tabs on which keys are carried by employees. Key control also involves the implementation of strategies that prevent employees from giving away duplicate keys to unauthorized users.
If you don’t have a key control system in place already, consider one for your business to increase employee safety, decrease workplace crime, and give you peace of mind.
What Are The Types of Key Control Systems?
With key control, there are mechanical systems and electronic systems. The differences between the two are as follows:
- Mechanical systems are an effective form of key control that enhances your facility’s overall security when used correctly. Simply put, these systems consist of a key with a plastic peg attached. The pegs are unique to each employee, serving to prevent keys from being removed unless the employee has the peg with specific clearance to remove it. The keys are also locked in a numbered port, and can only be removed after an access peg has been inserted. Mechanical systems help track which employees have accessed the keys, as their individual peg cannot be removed until the borrowed key is returned.
- Electronic systems are a more advanced form of key control that involve the newer technology of microchips . Keys are assigned to unique chips that are then inserted into a reader. The reader records when an authorized employee takes a key, and when it was returned. This advanced kind of key control system also lets others know which employee has a key if they request it and creates an audit trail of every key used and who used them.
What Are the Five Security Levels of Key Control?
The five security levels to key control are:
Level 5 – Key control systems with Level 5 security rely mostly on the honor system. This system has the lowest level of security and consists of unrestricted keys that employees are simply told not to make copies of. Employees are also warned not to give their keys to others and are trusted to comply with these rules, but there is no way for employers to track compliance.
Level 4 – Systems with Level 4 security involve unrestricted keys, however they are marked “do not duplicate.” This disclaimer is only semi effective, as the keys technically could still be copied anywhere. However, the majority of reputable locksmiths and key professionals will not copy them. The Associated Locksmiths of America, a nationwide trade organization for locksmiths, calls the “Do Not Copy” disclaimer a misleading tactic because it provides a false sense of security.
Level 3 – Systems with Level 3 security involve the use of restricted keys. These keys provide higher security as they can only be obtained through a single supplier. Restricted keys cannot be found at retailers, as they have to be obtained through the original source. The supplier of the key has rules set forth to prevent unauthorized duplication, giving business owners a certainty that only the keys they hand out will be able to access the designated restricted area
Level 2 – Key control systems with Level 2 security contain an even more restrictive set of keys. These are keys are patented, giving an extra boost of security as they are protected by patent law. If an individual attempts to sell or duplicate this key without getting permission from the patent holder, they could face legal penalties.
Level 1 – Systems with Level 1 security provide the highest level of security possible with a key control system. This level of security involves factory-only patented keys used to restrict access to designated areas. These keys have no possible way to be cut locally. In order to make copies, users have to send an authorization request to the original factory to have keys cut. In Level 1 systems, strict records are kept of who has access to each key, and when each key was used.

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.
As our homes get smarter, so do the tools we use to protect them. Smart locks have emerged as one of the most popular upgrades in modern home security—offering keyless convenience, remote control access, and sleek integration with smart home systems. But with any technology that connects to the internet, the looming question arises: Can smart locks be hacked?
Shared rental properties offer a unique living arrangement—blending affordability, flexibility, and social connection. But with these benefits come distinct challenges, especially when it comes to security. Unlike single-family homes or personal apartments, shared rentals often involve multiple people coming and going, limited privacy, and blurred boundaries of responsibility.
One of the most crucial decisions for landlords and property managers in these setups is choosing the right lock system. It’s not just about preventing break-ins; it’s about ensuring every tenant feels safe, trusted, and respected—while still allowing property access when needed.
Your front door is more than just a way in or out—it’s your first line of defense. It's where your home's security begins and often, unfortunately, where it ends. Despite having sturdy locks and alarm systems, many homes remain surprisingly vulnerable to forced entry. That’s because, in most break-ins, the problem isn’t the lock—it’s the door itself.
This is where door reinforcements come into play.
Whether you're in a bustling city apartment or a quiet suburban home, door reinforcements can drastically boost your overall safety. But how do they actually work? What kinds are available? And how can you install them effectively?
Lock bumping is a clever and disturbingly simple method used by burglars to unlock pin tumbler locks using a specially crafted “bump key.” While it sounds like something only professionals could pull off, the reality is that almost anyone with minimal knowledge and tools can do it—and that should concern every homeowner.

When it comes to securing your home, installing a deadbolt is one of the best decisions you can make. Deadbolts add an extra layer of protection that regular door locks often lack. However, if your door is made of metal rather than wood, you might be wondering if the installation process is even possible.
The simple answer is yes — you can install a deadbolt on a metal door. But as with many things involving metal, it takes the right approach, the right tools, and a careful hand to get it right.
