Buying Guide for Smart Home Deals
Security and Access Options
When choosing a smart lock, consider how you want to unlock the door. Fingerprint recognition, PIN codes, app control, and voice commands each offer different levels of convenience. The DESLOC B200 and B200L models support multiple methods, including Alexa and Google Assistant, so you can tailor access for family, guests, or service providers.
For rentals or Airbnbs, the DESLOC C100 provides one-time codes that expire automatically, reducing the risk of unauthorized entry. If you prefer a simpler setup without Wi-Fi, the C100 stores data locally for enhanced privacy.
Installation and Door Compatibility
Most smart locks are designed for DIY installation, but you should verify your door’s dimensions. Standard US doors with a 2-1/8 inch bore hole and adjustable backset (2-3/8 or 2-3/4 inches) work with all DESLOC models. The B200 and B200L fit both left and right-handed doors and require only a screwdriver.
If you’re upgrading from a traditional deadbolt, the process takes about 15 minutes. For more tips on home improvements, read our guide on choosing a lightweight folding rollator for mobility needs.
Battery Life and Backup Power
Smart locks rely on batteries, so longevity and backup options matter. The DESLOC K120 boasts a 16-month rechargeable Li-ion battery, while the B200 and B200L use four AA batteries lasting up to 12 months. All models include low-battery alerts and USB-C emergency ports, letting you power up with a portable charger if needed.
For the budget-conscious, the C100 also offers Type-C backup, making it a reliable choice for secondary doors. Compare with other smart home devices like the hatch vs sunrise alarm clock to see how they fit your routine.
Weather Resistance and Durability
If you plan to install a smart lock on an exterior door, weather resistance is critical. DESLOC locks are rated IP54 (B200, B200L, C100) or IP65 (K120), meaning they withstand rain, dust, and temperature extremes from -22°F to 158°F. The K120 is also BHMA Grade 3 certified for 100,000 cycles, ideal for high-traffic entrances.
For interior doors like home offices or garages, the B200L’s handle-integrated sensor offers a sleek, weatherproof design. If you’re looking for grabbers to reach high shelves, see our reacher grabber guide for convenience around the house.
Final Thoughts
This Black Friday, you can secure your home without breaking the bank.
