Keyless Check-In Is Now a Guest Expectation
Top picks compared — find your fit
The right smart lock eliminates key management headaches, enables self-check-in, and integrates with your PMS to auto-generate unique codes for every guest.
//01
Guests expect to check in on their schedule — not yours. A smart lock with automated code generation means your guests get a unique PIN an hour before arrival and it expires automatically at checkout. No lockboxes, no key handoffs, no phone calls at midnight when someone loses a key.
//02
Smart locks are one of the highest-ROI hardware investments in STR. A quality lock pays for itself within months when you factor in the time saved on key management and the uplift in guest satisfaction scores that comes with seamless self-check-in.
//03
The most important feature isn't the lock itself — it's the integration. A smart lock that talks to your PMS auto-generates unique guest codes, sends access instructions automatically, and alerts you if a door is left ajar. Connectivity and integration quality matter more than brand.

The criteria behind every VaultSTR ranking
//01
PMS and automation platform integration
Does it connect to your existing tools? Locks that integrate via direct API eliminate the need for middleware and reduce failure points.
//02
Code generation reliability
Do codes work every time, without fail? This is the most critical metric — a smart lock that generates unreliable codes creates a guest crisis at check-in.
//03
Battery life
How often will you need to change batteries? For remote properties, long battery life (12+ months) dramatically reduces maintenance trips.
//04
Connectivity
WiFi, Z-Wave, Zigbee, or Bluetooth? What hub is required? WiFi-native locks are simplest; Z-Wave offers more reliability but requires a hub.
//05
Tamper resistance and build quality
Will it hold up to heavy rental use? Commercial-grade locks stand up to the kind of traffic a successful STR property generates.
//06
Guest-friendliness
How easy is the keypad to use for first-time guests? Backlit keypads, large buttons, and clear confirmation feedback reduce check-in support calls.
Common questions answered
Most smart locks store guest codes locally, so doors will still unlock with the correct code even without an internet connection. The risk is that new codes won't generate and you won't receive alerts — which is why cellular-connected locks or Z-Wave locks with a hub are preferable for mission-critical properties.
The biggest guest support issue with smart locks is guests entering the code incorrectly. Set up your automated messaging to include a photo of the keypad and clear instructions. Most incidents resolve immediately once guests re-read the check-in instructions.
The major PMS platforms connect to most of the locks in this category via direct API or through an access management middleware like RemoteLock or Lynx. Check your PMS's integration directory before purchasing.
