The best smart locks to recommend to STR investor clients

The right smart lock eliminates your client's key-handoff anxiety before they even close. Airbnb's native integrations with Yale, August, and Schlage Encode/Encode Plus automate guest code generation, so the lock writes its own check-in messages. Our pick for most clients is the Yale Assure Lock 2 — most widely deployed in professionally managed vacation rentals, 9-12 month battery life, Matter-compatible.

The picks

Yale Assure Lock 2 — Best overall

Best for: most STR clients

Starting price: ~$260

Native Airbnb integration via the Yale/August app. Built-in Wi-Fi (no hub required) on the Wi-Fi version. 9-12 months on four AA batteries. Matter compatible (Apple HomeKit, Google Home, Alexa). 250-code capacity, more than the Schlage models. Available in touchscreen and physical keypad variants.

Pros

  • Native Airbnb integration
  • No hub required
  • Matter compatible
  • 250-code capacity
  • 9-12 month battery life

Cons

  • Not ANSI Grade 1 rated

Skip if: your client wants ANSI Grade 1 (highest residential security rating) — Schlage Encode Plus is the answer there.

What to tell your client: "This is what the professionally managed vacation rental down the street is using. It just works."

Schlage Encode Plus — Best for security-conscious clients

Best for: security-sensitive urban or luxury properties

Starting price: ~$329

Built-in Wi-Fi, no hub. ANSI/BHMA Grade 1 (the highest residential rating). Native Airbnb integration. 3-year warranty (longest in the category). Apple Home Keys support.

Pros

  • ANSI Grade 1 security rating
  • Native Airbnb integration
  • 3-year warranty
  • Apple Home Keys

Cons

  • Higher price point
  • Fewer code slots than Yale

Skip if: your client wants the cheapest path to native Airbnb integration — Schlage Encode (standard) is $30 cheaper for the same core integration.

What to tell your client: "If the property is in a high-traffic urban market or stores expensive amenities, Schlage's Grade 1 rating is worth the upgrade."

August Wi-Fi Smart Lock (4th Gen) — Best for HOA/condo restrictions

Best for: HOA, condo, or historic properties

Starting price: ~$200 + ~$50-$80 keypad

Retrofits onto the existing deadbolt without changing the exterior — critical for condos, historic districts, and any HOA that restricts hardware changes. Native Airbnb integration (Yale/August share parent company). 6-9 month battery life.

Pros

  • No exterior change required
  • Native Airbnb integration
  • Easy retrofit installation

Cons

  • Requires separate keypad purchase
  • Slightly shorter battery life

Skip if: your client's property has no exterior restrictions — Yale or Schlage are sturdier.

What to tell your client: "If you can't change the door's exterior, August is the only good answer. Tell your HOA you're not modifying the hardware."

igloohome Deadbolt 2S — Best for properties without reliable Wi-Fi

Best for: remote cabins, beach houses, mountain properties

Starting price: ~$160-$200

Patented algoPIN technology generates time-sensitive offline codes — the lock never needs to be online. Critical for remote cabins, beach houses with spotty Wi-Fi, and mountain properties. ~12-month battery life.

Pros

  • Works offline with algoPIN technology
  • Longest battery life (~12 months)
  • No internet required

Cons

  • No native Airbnb integration
  • Less seamless than Wi-Fi locks when internet is available

Skip if: your client's property has reliable internet — a Wi-Fi lock is better.

What to tell your client: "If the property is off-grid or has unreliable Wi-Fi, igloohome is the only lock that doesn't break."

Schlage Encode (standard) — Best value with native Airbnb integration

Best for: cost-conscious clients who want native integration

Starting price: ~$299

Same core integration as Encode Plus, slightly lower spec on the security rating (Grade 2) and warranty (1 year). The value play when Grade 1 isn't a priority.

Pros

  • Native Airbnb integration
  • Solid build quality
  • Lower price than Encode Plus

Cons

  • Grade 2 (not Grade 1) security rating
  • 1-year warranty only

Skip if: your client wants Grade 1 — Encode Plus is the upgrade for the security-conscious.

Ultraloq U-Bolt Pro — Best budget option with fingerprint

Best for: cost-sensitive clients already on Hospitable or Hostaway

Starting price: ~$189

Six entry methods including fingerprint. No native Airbnb integration — requires a PMS-level integration through Hospitable, Hostaway, or RemoteLock.

Pros

  • Fingerprint access
  • Six entry methods
  • Lower price point

Cons

  • No native Airbnb integration
  • Requires PMS layer for code generation

Skip if: your client wants the simplest possible setup — the PMS layer adds a step.

What to tell your client: "If price matters and your PMS handles code generation, Ultraloq is real money saved."

Who should recommend what

Default for almost all clients: Yale Assure Lock 2. Security-sensitive urban or luxury: Schlage Encode Plus. Condo, HOA, or historic property where the exterior can't change: August Wi-Fi. Off-grid cabin or unreliable Wi-Fi: igloohome. Cost-sensitive client already running Hospitable or Hostaway: Ultraloq via PMS integration.

Bottom line

Smart locks are one of the highest-ROI hardware purchases an STR owner will make: $150-$330 one-time, no monthly fees, eliminates 30+ minutes per stay in key logistics. Yale is the safest recommendation. Schlage Encode Plus is the upgrade for security. The other choices are for specific constraints.

FAQ

Does Airbnb really auto-generate codes?
Yes, for native integrations with Yale (with August keypad), Schlage Encode/Encode Plus, and August lock + keypad. The lock generates a unique code for each booking, sent through Airbnb 48 hours before check-in, deactivates at checkout.
What happens if the Wi-Fi goes out?
All recommended locks support physical key backup. Most also support emergency 9V power. Your client should keep a spare key in a lockbox onsite.
How long does installation take?
~10 minutes for retrofit (August), 20-30 for full deadbolt replacement (Yale, Schlage). Most clients DIY without a locksmith.
Will the lock work in extreme cold or salt air?
For cold climates: Schlage Encode, lithium batteries. For coastal/salt air: Yale Assure Lock 2 Pro is built specifically for it.
