What separates great smart locks from ones that cause headaches

Three features that matter most when you're turning over dozens of guests monthly.

Automatic guest code generation from your PMS

The lock syncs directly with your property management system. Guest codes generate automatically at check-in and expire at checkout. No manual code entry. No codes that don't work. No guests locked out because you forgot to update the app.

Reliable battery life in real-world conditions

Specs say 12 months. Reality is different depending on traffic, temperature, and wifi strength. Smart lock claims often fall short. The best performers maintain consistent battery life across properties and climates, with clear low-battery warnings and easy replacement.

Installation that actually works without a locksmith

Some locks require professional installation. Others fit standard deadbolts and go in with a screwdriver. The difference is hundreds of dollars per property if you're installing across a portfolio. Compatibility matters. Fit matters. Installation support matters.

How to choose the right smart lock for your STR operation

A checklist operators use to evaluate locks before installing across properties.

Verify PMS integration with your specific system

Not all smart locks integrate with all PMS platforms. Check compatibility. Test the integration in a trial. Make sure automatic code generation actually works. Ask the lock company for a reference operator who uses your PMS.

Test installation on one property before rolling out

Order one lock and install it yourself. Does it fit your deadbolt? Can you complete installation without calling for help? Is the app intuitive? If installation is a struggle on one property, it'll be a struggle on ten.

Establish a battery replacement schedule

Know how often you'll need to replace batteries. Plan replacement before you get low-battery alerts. Some operators replace every 9 months as preventative maintenance. Others monitor and replace on demand. Pick your approach before you install.
