There’s a specific kind of unease that settles in when you realize a part of your home isn’t as secure as you thought. For me, that moment came while looking at our back door. It’s a beautiful door with a large, inviting glass pane in the upper half—great for letting in natural light, but terrible for peace of mind. I imagined how easily a potential intruder could shatter that small pane, reach inside, and simply turn the thumb latch on our standard deadbolt. The strongest part of our home’s defense could be bypassed in seconds. This isn’t just a problem for doors with windows; it applies to any door near a sidelight window, a mail slot, or even a pet door. The convenience of a thumb-turn lock becomes a glaring security flaw, turning a formidable barrier into little more than a suggestion. That realization sent me on a search for a more robust, traditional solution—a lock that couldn’t be defeated from the inside without the proper key.

What to Consider Before Buying a Double-Cylinder Deadbolt
A deadbolt is more than just a piece of hardware; it’s a key solution for hardening your home’s entry points against forced entry. Unlike a spring-bolt latch found in a standard doorknob, a deadbolt’s mechanism doesn’t rely on a spring and can’t be easily jimmied open with a credit card or knife. It must be physically retracted. A double-cylinder deadbolt takes this security a step further by requiring a key on both the interior and exterior sides. This eliminates the vulnerability of a thumb-turn latch, making it an essential upgrade for any door where an intruder could potentially access the interior side of the lock.
The ideal customer for this type of product is someone facing that exact security dilemma: a homeowner with glass-paneled doors, a workshop owner wanting to prevent easy exit, or someone securing an interior door to a home office or storage room. It provides absolute control over who can lock or unlock the door, from either side. However, it might not be suitable for every situation. For primary exit doors in a home with young children or elderly individuals, a double-cylinder lock can pose a safety hazard during an emergency like a fire, as it can slow down evacuation if the key isn’t readily accessible. In these cases, a high-security single-cylinder deadbolt or a modern smart lock might be a more appropriate alternative.
Before investing, consider these crucial points in detail:
- Dimensions & Space: The first step is always to measure. Check your door’s thickness and the backset—the distance from the edge of the door to the center of the borehole. The Rulart lock is designed for standard doors, fitting thicknesses from 1-3/8″ to 2″ and offering an adjustable backset for both 2-3/8″ and 2-3/4″ configurations, which covers the vast majority of residential doors.
- Security & Performance: Look at the core components. Is the bolt made of solid, hardened steel? What is the cylinder made of? The Rulart boasts a solid steel latch and a solid copper cylinder keyhole, materials chosen for their resistance to drilling and brute force. Features like anti-pry shields and reinforced strike plates add critical layers of defense against common attack methods.
- Materials & Durability: The lock’s exterior will be exposed to the elements. Stainless steel, like the satin finish on the Rulart model, is an excellent choice for its high resistance to rust and corrosion, ensuring it looks good and operates smoothly for years. This is often a more durable choice for exterior applications than finishes like polished brass, which may tarnish over time without a protective coating.
- Ease of Use & Maintenance: A mechanical lock like this is straightforward but requires correct installation to function properly. Misalignment is the number one cause of sticky or non-functioning deadbolts. Long-term, a simple spray of graphite lubricant into the keyway once a year is all it takes to maintain smooth operation.
Keeping these factors in mind, the Rulart Double Keyed Deadbolt Lock Satin Stainless Steel stands out in several areas, particularly for its robust materials and versatile fit. You can explore its detailed specifications here.

First Impressions: Solid, Sleek, and Ready for Duty
Upon unboxing the Rulart Double Keyed Deadbolt Lock Satin Stainless Steel, the first thing we noticed was its reassuring heft. At a solid pound, it doesn’t feel like a cheap, hollowed-out piece of hardware. The satin stainless steel finish is clean, modern, and fingerprint-resistant, giving it a premium look that would complement a wide range of door styles and handle sets. Inside the box, the layout is simple and efficient: the two cylinder housings, an adjustable latch, a strike plate, three uniquely cut keys, mounting screws of two different lengths, and a folded instruction sheet. Every component felt well-machined with no sharp edges or blemishes. The solid steel of the deadbolt itself extends and retracts with a satisfying, solid clunk when tested by hand. Compared to some budget locks that can feel flimsy, the Rulart immediately gives the impression of being a serious piece of security equipment built for durability.

Performance Deep Dive: Putting the Rulart Deadbolt to the Test
A lock’s true worth is revealed not on the shelf, but on the door, after weeks of daily use and a meticulous installation process. We put the Rulart Double Keyed Deadbolt Lock Satin Stainless Steel through its paces, focusing on the entire user experience from installation to its core function as a security device.
Installation: A Tale of Two Experiences
Reading through user feedback, a clear divide emerges: some found this to be the easiest lock they’ve ever installed, while others were left with a non-functional, frustrating piece of metal. Our experience landed squarely in the middle and revealed the critical importance of a single, often-overlooked step in the instructions. Out of the box, the process seems deceptively simple: insert the latch, slide the exterior cylinder in, then the interior cylinder, and tighten two screws. The entire process *can* take less than 15 minutes, as one user happily reported.
However, the make-or-break moment comes when aligning the two halves. The exterior piece has a flat torque blade (the “fork”) that must pass through the latch mechanism. The interior piece also has one. As one insightful user noted, you must ensure “one fork [is] horizontally and one fork [is] vertically.” The instructions illustrate this, but it’s easy to miss if you’re rushing. If you fail to align them correctly, you’ll experience the exact issues mentioned in negative reviews: the key will spin endlessly without engaging the bolt, or the bolt will get stuck and refuse to fully extend or retract. We intentionally installed it incorrectly first and immediately reproduced this problem. The key turned, but nothing happened. After disassembling and taking 30 seconds to ensure the torque blades were properly oriented (one vertical, one horizontal), we reassembled it. The difference was night and day. The lock functioned perfectly, with a smooth and decisive action. This confirms our suspicion that the most severe functional complaints are likely due to installation error, not a fundamental design flaw.
Security in Depth: More Than Just a Lock
The primary reason to buy the Rulart Double Keyed Deadbolt Lock Satin Stainless Steel is for its security, and here it truly excels. The double-cylinder design is the star feature. For our back door with its large glass pane, this lock is a game-changer. It provides genuine peace of mind, just as one user felt when installing it on their porch door. No matter what happens to the glass, that door isn’t opening without a key.
Beyond the design, the material strength is evident. The solid steel latch bolt is the part that physically secures the door. Its heft and construction are designed to resist brute force attacks like kicking or shoulder rams. The solid copper cylinder adds another layer of protection against more subtle attacks like drilling. Rulart also claims the lock is anti-pry and anti-collision, and the robust housing and tight fit seem to support this, leaving little room for a pry bar to gain purchase. For anyone prioritizing this level of uncompromising mechanical security, this lock delivers on its core promise. You can find this high-security deadbolt available here.
An unexpected but highly valuable feature we discovered, thanks to user feedback, is that the lock appears to use a KW1 keyway. This is the standard keyway used by Kwikset locks. For a DIY-savvy homeowner, this is a massive advantage. It means if the rest of your home uses Kwikset locks, you can purchase a simple re-keying kit and adjust the Rulart lock to work with your existing house key. This eliminates the need for another key on your keychain and integrates this high-security lock seamlessly with your home’s existing hardware—a professional-level feature on a very accessibly priced lock.
Day-to-Day Operation and Aesthetics
In daily use, a well-installed Rulart deadbolt is a pleasure to operate. The key action is smooth and confident. We found no sticking, grinding, or hesitation when locking or unlocking from either side, a sentiment echoed by users who praised its smooth operation. The mechanism engages with a solid, audible “thunk,” leaving no doubt that the door is secure. Each lock set is keyed differently, so you don’t have to worry about a neighbor’s key opening your lock, providing an extra layer of security.
Aesthetically, the satin stainless steel finish is both beautiful and practical. It has a modern, understated elegance that matched our existing door handle perfectly, just as another customer experienced. The finish is excellent at resisting fingerprints and smudges, meaning it stays looking clean with minimal upkeep. Over several weeks of testing, including exposure to rain and humidity on our exterior gate installation, the finish showed no signs of spotting or corrosion. It’s a lock that not only performs its security function flawlessly but also enhances the look of the door it’s installed on.
What Other Users Are Saying
Synthesizing feedback from various users provides a very clear picture of the Rulart Double Keyed Deadbolt Lock Satin Stainless Steel. The sentiment is largely positive, with many people calling it a “very nice product” that was “exactly what I needed.” The ease of installation is a frequent point of praise for those who successfully follow the directions. One user, who installed it in under 10 minutes, was “shocked others have so many problems,” highlighting the importance of proper procedure. Another user astutely pointed out how a negative review complaining about key operation was almost certainly an installation error, a conclusion our own testing confirmed.
However, the negative feedback points to a legitimate concern: quality control. Several users reported receiving locks that were clearly used, incomplete, or broken right out of the box. One described the deadbolt as “absolute garbage” because it wouldn’t extend fully upon arrival, while another received a unit with a missing internal component. While these appear to be outliers, they suggest a potential inconsistency in the packing and inspection process. It seems that if you receive a good unit, you’ll be very happy, but there is a non-zero chance of needing to process a return for a defective item.
How Does the Rulart Deadbolt Compare to the Alternatives?
The Rulart lock represents the pinnacle of traditional, mechanical security. But how does it stack up against modern, smart alternatives? For many, the choice comes down to security philosophy: foolproof mechanics versus high-tech convenience.
1. SMONET Keyless Entry Smart Lock with Handle Fingerprint Bluetooth Digital Keypad Auto Lock Black
- Front Door Lock Set Keyless Entry - 7-in-1 smart lock provides you with Anti-peep keypad passcode, physical keys and fobs, smartphone App Bluetooth...
- Smart Lock with Handle - This electronic deadbolt door lock supports sharing ekey or code to your family, permanent access, specific dates or periods of...
The SMONET lock is a complete front door overhaul. It’s a full handle set that offers a staggering number of entry methods: fingerprint, keypad code, Bluetooth app, key fob, voice command via Alexa, and a traditional key. This is for the homeowner who wants maximum convenience and connectivity. Compared to the Rulart’s singular focus on keyed security, the SMONET is about flexible access for family, friends, and service providers. The trade-off is complexity and reliance on batteries and electronics. If you prioritize remote access and a feature-rich experience over simple mechanical brute strength, the SMONET is a compelling alternative.
2. ULTRALOQ Latch 5 Smart Lock Fingerprint Keyless Entry
- 【Multiple Ways to Unlock】World's first built in WiFi keyless entry door lock, App + Fingerprint + Code + Mechanical Key.
- 【Ideal for Rental Homeowners and Homeowners】Built-in WiFi allows you to share temporary passwords to your guests via smartphone app remotely. No WiFi...
The ULTRALOQ Latch 5 strikes a balance between the Rulart’s simplicity and the SMONET’s complexity. It replaces a standard doorknob or lever, not a deadbolt, but offers 5-in-1 keyless entry including a fingerprint scanner. Its standout feature is built-in WiFi, which allows for remote control and monitoring without needing a separate, plugged-in bridge. This is for the user who wants to upgrade to smart, keyless convenience without replacing their entire handle set and who values direct-to-internet connectivity. It offers a different type of security—one based on access logs and remote control—rather than the purely physical barrier provided by the Rulart.
3. Veise Keyless Entry Door Lock Auto Lock
- Keyless Entry: With 20 password code + 2 spare keys + one-time password for temporary visitors, the one-time code will automatically deleted after use
- Smart and Convenient: With anti peeping function when entering passwords, and the front door lock set can 'auto lock' in 10-99 seconds, or press a key for...
The Veise deadbolt is the most direct competitor in terms of function, as it’s also a standalone deadbolt. It represents a gentle step into keyless technology. It forgoes the bells and whistles like fingerprint readers and WiFi for a reliable, backlit electronic keypad. Features like auto-lock and anti-peeking password entry provide significant convenience and security enhancements over a standard lock. Someone would choose the Veise over the Rulart if their primary goal is to stop carrying keys, while still wanting the security of a solid deadbolt. The Rulart remains the choice for those who need the specific security of a double-cylinder design or prefer a lock with no electronic failure points.
Final Verdict: An Outstanding Value for Targeted Security Needs
After extensive hands-on testing and analysis, our verdict on the Rulart Double Keyed Deadbolt Lock Satin Stainless Steel is overwhelmingly positive, with a slight caveat. For its intended purpose—providing high-level, physical security for doors vulnerable to interior access—it is an exceptional product. Its robust construction, quality materials, and foolproof double-key design offer genuine peace of mind that electronic locks cannot always match. When installed correctly, it operates with the smooth precision of a much more expensive piece of hardware.
We would strongly recommend it to any DIY-savvy homeowner looking to secure a glass-paneled door, a workshop, or a gate. The key is to read and follow the installation instructions meticulously to avoid the alignment pitfalls that have frustrated some users. While the reports of quality control issues are a valid concern, the lock’s performance and value when you get a good unit are undeniable. It’s a straightforward, effective, and affordable solution to a common and serious security problem.
