Designed for homeowners, renters, and busy professionals, it replaces traditional keys with a responsive tactile keypad, Bluetooth, and Wi-Fi control. With a 4.5-star rating from over 500 reviews, it has quickly become a popular choice for those seeking a reliable smart lock without the premium price tag.
Standout features include the backlit keypad with up to 200 customizable codes and an anti-peep password that lets you add random digits before and after your real code. The Tapo app provides remote lock/unlock, real-time notifications, and detailed activity logs. Auto-lock with adjustable timing and a PIN attempt limiter add extra peace of mind. Users consistently praise the fast Wi-Fi response and the convenience of managing access for family, guests, and service providers.
Build quality is solid with a metal exterior that feels durable and a BHMA Grade 3 certification for long-lasting performance. The IP54 weatherproof rating means it can handle rain, dust, and temperature extremes from -22°F to 158°F. Installation is straightforward on standard doors, though a few users note that the interior unit is plastic and may require minor adjustments for a perfect fit.
One common drawback is battery life: while rated for up to 200 days on Wi-Fi, some users report faster drain, especially with constant Wi-Fi connection. The included batteries are basic, so using high-quality alkaline or lithium cells is recommended. The Tapo branding on the exterior is subtle but may not appeal to everyone.
Overall, the Tapo DL100 offers excellent value for money. It combines essential smart lock features with robust security and ease of use. If you are looking for a dependable, keyless deadbolt that integrates with Alexa, Google Home, or SmartThings, this is a strong contender. Just be prepared to monitor battery life and possibly tweak the installation for your specific door.
Buying Guide: What to Look for in a Smart Lock Without WiFi
Security and Build Quality
The lock’s physical durability matters. Look for BHMA certification (Grade 1 is highest; Grade 3 is adequate for standard homes). A metal construction and a sturdy deadbolt deter forced entry. Both the Schlage and Tapo locks we reviewed carry Grade 3 certification, ensuring long‑term reliability. Also consider features like an alarm for tampering or forced entry attempts.
Access Methods Without WiFi
Even without WiFi, you need reliable ways to unlock your door. A backlit keypad allows code entry day or night. Bluetooth lets you unlock with your phone when nearby. And physical backup keys ensure you’re never locked out. The Schlage Encode offers a touchscreen keypad plus a physical key; the Tapo adds tactile buttons and Bluetooth. Both support up to 100 to 200 custom codes, perfect for family or guests.
Battery Life and Emergency Power
A lock that dies mid‑use is a hassle. Choose models with at least six months of battery life under normal use. The Tapo DL100 boasts up to 200 days in WiFi mode and 300 in Bluetooth mode. Both use AA batteries and include low‑battery alerts. Emergency power via a USB‑C port (Tapo) or a 9V battery backup (many models) is a smart fallback.

Installation and Compatibility
You want a lock you can install yourself without calling a locksmith. Both the Schlage and Tapo fit standard doors (1.375 to 1.75 inches thick) with 2.375 or 2.75 inch backset. The Schlage’s Snap ‘n Stay feature holds the lock in place while you secure it; the Tapo includes clear instructions. No hardwiring required, just a screwdriver.
Final Thoughts
Both the Schlage Encode Smart WiFi Deadbolt Lock and the Tapo Smart Wi-Fi Deadbolt Door Lock excel as smart locks that work reliably without WiFi. The Schlage offers premium build, a scratch‑resistant touchscreen, and Alexa/Google voice control, making it ideal for tech‑savvy homeowners who want the option of WiFi but don’t need it to lock and unlock. The Tapo delivers exceptional value with its long battery life, tactile keypad, and Bluetooth access, perfect for renters or budget‑conscious buyers who prioritize offline versatility. Whichever you choose, you’ll get a dependable lock that keeps your home secure even when your network goes down.
Frequently Asked Questions
Can I use a smart lock without WiFi at all?
Yes, many smart locks are designed to work offline via a keypad, Bluetooth, or physical key. Even WiFi‑enabled locks like the Schlage Encode and Tapo DL100 can be used without an internet connection for everyday locking and unlocking. WiFi is only needed for remote control or notifications, not for core access.
Do these locks have backup keys?
Both models include traditional backup keys. The Schlage Encode comes with one physical key, and the Tapo DL100 includes two. This ensures you can always enter your home if the battery dies or if you forget the code.
How long do the batteries last in offline mode?
Battery life varies. The Tapo DL100 lasts up to 300 days in Bluetooth‑only mode and up to 200 days with WiFi enabled. The Schlage Encode typically provides about six months of battery life under normal use. Low‑battery alerts in the app and on the keypad help you plan replacements.
Are these locks weather resistant for outdoor use?
The Tapo DL100 has an IP54 rating, meaning it resists dust and water splashes, making it suitable for covered outdoor installs. The Schlage Encode is designed for interior use but its fingerprint‑resistant touchscreen withstands typical door exposure. For best results, install under a porch roof or overhang.
