Buying Advice: Match the Lock to Your Door

Five common situations, five clear picks. If you recognize yourself in one of these, that's your model.

💰

Tightest budget

→ DESLOC B200

At $59.99 it's the cheapest BHMA-certified fingerprint deadbolt worth installing. Add the $31.99 G2 Gateway later if you decide you need remote control.

🏠

Rental or Airbnb host

→ DESLOC K120

Landlord Mode handles group access, temporary codes and scheduling. 13-month battery means fewer site visits, and the 3D sensor keeps working on wet or worn fingers.

🛡️

Security first

→ DESLOC K140 Plus

Palm vein biometrics can't be spoofed with a lifted fingerprint, and everything is stored locally on the lock — nothing in the cloud.

🔋

Set it and forget it

→ DESLOC V150 Plus

Solar self-charging plus 8+ months of reserve battery. If the lock sits on a hard-to-reach door, this is the one you'll never climb a ladder for.

📶

No-hub smart home

→ DESLOC D110 Plus

True built-in Wi-Fi under $100. Remote lock, unlock and notifications straight through the app with nothing extra plugged into the wall.

Door fit check before you buy: all five models replace a standard US deadbolt and install with a screwdriver in roughly 10–15 minutes. The B200 is the only one that ships without batteries (it takes 4×AA) — every other model includes its rechargeable pack. If your door gets direct sun or driving rain, favor the IP65-rated K120 or V150 Plus over the IP54 B200.

Frequently Asked Questions

The questions we actually get asked about DESLOC, answered from the official spec sheets.

Are DESLOC locks any good?

For the price, yes. DESLOC (sold by DefendNet LLC, Dover, Delaware) backs its locks with a 30-day money-back guarantee, up to 24 months of warranty and 24/7 support, and the lineup averages 4.8/5 across 2,400+ verified reviews on desloc.com. The K120 and K140 Plus are the strongest performers: BHMA Grade 3 deadbolts with biometric false-accept rates published right on the official spec sheets.

Do DESLOC locks need a hub or gateway?

Not anymore. The D110 Plus, K120, K140 Plus and V150 Plus all have built-in Wi-Fi and connect straight to the DESLOC app. Only the entry-level B200 is Bluetooth-first — it needs the $31.99 G2 Gateway for remote access and voice control.

What happens if the battery dies?

Every model has a USB-C emergency port (the K120 has a built-in cable) so you can jump it with a power bank. AA models also keep a physical key override. The K120 drops into an Ultra-Save mode below 5% that stretches standby up to 12 more months, and the V150 Plus trickle-charges itself from ambient light.

Are DESLOC locks weatherproof?

The B200 is rated IP54 and operates from −22°F to 158°F. The K120 and V150 Plus step up to IP65 with BHMA Grade 3 certification — fine for exposed front doors in rain, snow and southern heat.

Which is better, fingerprint or palm vein?

Palm vein reads the vein pattern inside your hand, so it works when fingerprints fail — dry skin, wet hands, shallow prints — and can't be cloned from a touched surface. DESLOC publishes a <0.0001% false-accept rate for the K140 Plus versus <1/1,000,000 for the K120's fingerprint. Both store biometrics locally on the lock. If your budget allows, palm vein is the more future-proof choice.
