Luston Slim Smart Mortise Lock
ADVANTAGES
LIMITATIONS
The Luston Slim Smart Lock is a game-changer for multipoint locking doors, delivering a rare blend of precision engineering and smart versatility. With its 7-in-1 unlocking system—fingerprint, smartphone app, passcode, key fobs, mechanical keys, Apple Watch, and NFC—it ensures no more lockouts, no matter your scenario. Its standout feature is the mortise compatibility with the standard 3585 size, making it one of the few smart locks built specifically for heavy-duty, European-style swing doors that demand robust security and smooth integration. For homeowners tired of retrofitting round deadbolts onto incompatible doors, this lock is a precision-fit solution that just works.
In real-world testing, the Luston shines in multi-access environments—like family homes or rental units—where managing access is critical. The free, lifetime app allows remote generation of one-time codes, perfect for Airbnb hosts or cleaning crews, while the detailed unlock history log adds a layer of accountability. It handles outdoor installations with confidence thanks to its waterproof, stainless-steel construction, but be mindful: the 45-degree handle rotation limit means it won’t work if your door’s existing handle requires more downward pressure to fully retract all locking points. While Bluetooth control is solid, Wi-Fi functionality requires a separate gateway, which can be a hassle for users expecting full remote access out of the box.
Compared to the Lockly Secure Pro, the Luston trades universal Wi-Fi convenience for specialized door compatibility, making it less of an all-rounder but a top-tier specialist. It’s the clear choice over igloohome or Lockly if you’re dealing with a multipoint metal latch system—a common setup in modern steel or aluminum swing doors. Where Lockly wins on speed and igloohome on price, Luston dominates in mechanical precision and retrofit reliability for non-standard doors. If your door type aligns, this lock offers better long-term value than a generic deadbolt with adapter kits.
Lockly Secure Pro (2025 Version)
ADVANTAGES
LIMITATIONS
The Lockly Secure Pro (2025) is a powerhouse of smart security, engineered for those who demand lightning-fast, hack-proof access without sacrificing convenience. Its new-gen AI-powered fingerprint sensor unlocks in just 0.2 seconds with near-flawless accuracy, even with damp or partially worn fingers—something many rivals struggle with. The PIN Genie keypad is a brilliant anti-snooping innovation, reshuffling number positions after every use, making shoulder surfing futile. For families or busy households, the ability to store 99 fingerprints and 49 unique PINs makes it a true multi-user champion right out of the gate.
Performance-wise, the built-in Wi-Fi is a major leap forward, eliminating the need for a hub and enabling 98% faster remote access than older models. Whether you’re unlocking the door for a pet sitter from your office or checking lock status during a storm, the Lockly app responds instantly with real-time notifications and eKey sharing. The auto-lock feature is rock-solid, customizable from immediate to delayed, and the rekeyable cylinder is a godsend—no need to replace the entire lock if keys are lost. However, in extreme cold or humid conditions, the fingerprint sensor occasionally requires a second swipe, a minor hiccup in an otherwise flawless experience.
Positioned between the budget igloohome and the niche Luston, the Lockly Secure Pro is the best overall smart lock for standard deadbolt doors. It outperforms the igloohome in speed and security, and unlike the Luston, it’s plug-and-play with no compatibility guesswork. It’s ideal for homeowners who want set-and-forget reliability with premium features like Alexa and Google Assistant voice control. While it costs more than the igloohome, it delivers far superior remote functionality and peace of mind than any budget model can match.
igloohome Deadbolt Go Smart Lock
ADVANTAGES
LIMITATIONS
The igloohome Deadbolt Go is a stealthy budget hero that punches far above its price tag with smart engineering and elegant simplicity. Don’t let the low cost fool you—this lock delivers fingerprint access, tactile keypad input, and smartphone control in a sleek, ANSI-tested body built for daily durability. Its algoPIN technology is a standout, letting you generate time-limited, revocable remote PINs from anywhere—perfect for dog walkers or repair folks—while the physical keypad’s raised buttons make blind entry easy, even in the dark. For renters or first-time smart lock adopters, it’s a low-risk, high-reward entry point into keyless living.
In real-world use, the deadbolt operates smoothly with consistent Bluetooth response and reliable auto-relock (configurable from 5 to 180 seconds). Installation is a breeze with just a screwdriver, and the minimalist matte black finish resists smudges and scratches. However, full remote access requires the WiFi Bridge, sold separately, which undercuts the out-of-box experience—local Bluetooth only works within ~30 feet. While it integrates with select voice assistants, the lack of built-in Wi-Fi means you’ll pay extra for true remote control, a hurdle for tech-casual users.
Against the Lockly and Luston, the igloohome is the clear budget king, but it’s not a one-size-fits-all solution. It lacks the raw speed of Lockly’s fingerprint sensor and the specialized fit of the Luston, but for a standard door on a tight budget, it’s unbeatable in value. It’s perfect for apartments, second homes, or Airbnb hosts who want secure, code-based access without overspending. While it demands a bit more setup for full functionality, it offers more smart features at half the price of premium models.
Choosing the Right Smart Lock
Key Considerations for Your Smart Lock
When selecting a smart lock, focusing on how well it meets your security needs, convenience preferences, and existing door setup is crucial. Several features contribute to a smart lock’s overall value. Here’s a breakdown of the most important factors to consider:
1. Access Methods & Convenience
The core benefit of a smart lock is keyless entry, but how you access your home matters. Fingerprint recognition (like in the Lockly Secure Pro and igloohome Deadbolt Go) offers quick, secure access, requiring only a touch. Keypad entry (featured in all models) provides a backup and is convenient for guests or family members. Smartphone app control (all models) adds remote access and management capabilities. Consider how you and others will most frequently access the home – a mix of methods is often best. More access methods can be more convenient, but also potentially introduce more points of failure or complexity.
2. Connectivity & Remote Access
Remote access – the ability to lock/unlock your door from anywhere – is a major smart lock advantage. The Lockly Secure Pro stands out with its built-in Wi-Fi, offering faster and more reliable remote control without needing a separate hub. Other models, like the igloohome Deadbolt Go, often require a bridge (sold separately) to achieve this functionality, adding to the overall cost and complexity. If reliable remote access is a priority, a built-in Wi-Fi solution is preferable. Evaluate how often you anticipate needing remote access and whether the added cost of a bridge is justifiable.
3. Security Features
Beyond keyless entry, robust security features are paramount. The Lockly Secure Pro’s PIN Genie keypad, which randomizes PIN codes, is a strong deterrent against guessing. All reviewed models offer multiple layers of security, including physical keys as a backup. Consider the ANSI grading (igloohome) which indicates the lock’s physical security against forced entry. The ability to manage user access (granting temporary codes, etc.) is another vital security feature.
Other Important Features
- Battery Life: Smart locks rely on batteries. Consider the type (AA, etc.) and estimated lifespan.
- Door Compatibility: The Luston Slim Smart Mortise Lock specifically highlights mortise lock compatibility, crucial for certain door types. Ensure the lock fits your existing door and hardware.
- Smart Home Integration: Compatibility with voice assistants (Alexa, Google Assistant) adds convenience.
- Installation: DIY installation is possible with many models (like the igloohome), saving on professional fees.
- Rekeyability: The ability to rekey the lock (Lockly Secure Pro) allows you to change keys without replacing the entire unit.
- Audit Trails: Checking unlock records (Luston) can provide insights into who accessed your home and when.
