Exterior Smart Lock Review
How to Choose the Right Exterior Smart Lock
Choosing the right smart lock for your home involves considering several key features to ensure it meets your security needs and lifestyle. Here’s a breakdown of what to look for:
Access Methods & Convenience
The core benefit of a smart lock is convenient access. Consider how you want to unlock your door. Many locks offer multiple methods, including fingerprint recognition, PIN codes, smartphone app control, physical keys, and even key fobs. Fingerprint locks (like the Philips Smart Lock with Handles or Yamiry Fingerprint Smart Knob) are incredibly fast and secure, eliminating the need to remember codes or carry keys. PIN code access is great for family members or trusted visitors, while app control allows remote access – a crucial feature for letting in guests or checking lock status when away from home. Consider how many users you need to grant access to and whether temporary, one-time use codes are important (TEEHO TE001 and DESLOC Smart Door Lock B200 offer such features).
Connectivity & Smart Home Integration
Smart locks vary in their connectivity options. Some, like the Schlage Encode Smart WiFi Deadbolt and eufy Security Smart Lock C30, have built-in WiFi, allowing direct connection to your home network and remote control via a smartphone app. Others require a separate gateway or hub (like the Sifely Biometric Smart Lock or DESLOC Smart Door Lock B200 with its G2 Gateway) to achieve remote access. If you already have a smart home ecosystem (Amazon Alexa or Google Home), ensure the lock is compatible for voice control and seamless integration. This allows you to lock/unlock your door with voice commands and potentially incorporate the lock into automated routines.
Security Features
Security is paramount. Look for locks with robust security features. Features like auto-lock (found in most models) automatically secure your door after a set time, preventing accidental leaving-unlocked situations. Encrypted communication is vital to prevent hacking. Some locks, like the Schlage Encode, boast BHMA certifications, indicating they’ve met stringent industry standards for security and durability. Consider features like tamper alarms (Schlage Encode) and anti-peeping PIN code protection (DESLOC B200) for added peace of mind.
Installation & Compatibility
Installation difficulty can vary. Many smart locks are designed for DIY installation, requiring only a screwdriver (TEEHO TE001, Philips Smart Lock with Handles). However, some may require more technical expertise or specific door preparations. Crucially, check your door’s compatibility (thickness, backset) before purchasing. Most locks fit standard doors, but it’s essential to verify. Consider the power source – most run on AA batteries, but battery life varies significantly (eufy C33 boasts up to 12 months) and look for models with low-battery alerts and emergency power options (DESLOC B200).

How We Tested Exterior Smart Locks
Our evaluation of exterior smart locks centers on a data-driven approach, combining publicly available information with detailed feature analysis. We prioritize locks with documented security certifications, such as BHMA grading, and scrutinize reported vulnerability disclosures. Performance data – including app ratings, user reviews from verified purchasers (Amazon, Best Buy, manufacturer websites), and independent testing results (Consumer Reports, Wirecutter) – informs our assessments.
We analyze connectivity reliability, focusing on WiFi signal strength tests and reported integration success rates with major smart home platforms (Amazon Alexa, Google Home, Apple HomeKit). Battery life claims are verified against user reports and, where possible, independent testing. Comparative analyses highlight key differences in access methods (fingerprint, keypad, app), encryption protocols, and physical construction.
While comprehensive physical product testing isn’t always feasible, we leverage detailed specifications, teardown reports (where available), and expert reviews to assess build quality and potential weaknesses of each smart lock model. This research-based methodology ensures our recommendations are grounded in evidence and prioritize both security and user experience. We specifically look for data relating to successful/failed lock attempts and reported instances of false positives/negatives to gauge real-world reliability.
FAQs
What is a BHMA certification and why is it important for an exterior smart lock?
BHMA (Builders Hardware Manufacturers Association) certification indicates that the exterior smart lock has been tested and meets specific industry standards for security and durability. This certification provides assurance that the lock offers a reliable level of protection against forced entry and manipulation.
Do I need a separate hub or gateway to use a smart lock remotely?
Not always. Some smart locks, like the Schlage Encode, have built-in WiFi and connect directly to your home network. Others, such as the Sifely or DESLOC models, require a separate gateway or hub for remote access and smart home integration. Check the lock’s specifications to determine its connectivity requirements.
What should I consider when checking compatibility with my door?
Before purchasing an exterior smart lock, verify your door’s thickness and backset (the distance from the edge of the door to the center of the bore hole). Most locks fit standard doors, but it’s crucial to confirm compatibility to avoid installation issues.
What are the benefits of fingerprint access on a smart lock?
Fingerprint access offers a fast, secure, and convenient way to unlock your door without needing keys or remembering PIN codes. It’s a highly secure method, as fingerprints are unique to each individual, enhancing the overall security of your smart lock system.
The Bottom Line
Ultimately, the best exterior smart lock depends on your individual needs and existing smart home setup. Prioritize features like robust security certifications, convenient access methods, and seamless integration with your preferred voice assistant for a truly enhanced and secure home experience.
Investing in a smart lock offers significant benefits, from keyless entry to remote access control and increased peace of mind. By carefully considering the factors outlined above – connectivity, security, and compatibility – you can choose a smart lock that provides both convenience and reliable protection for your home.
