A smart lock is the modern default for hassle-free arrival, letting you skip key handoffs entirely and check in on your own schedule. It's closely related to but distinct from Airbnb's "self check-in" filter — self check-in also covers lockboxes and keypads that require a physical code, whereas a genuine smart lock (app-based or keypad-integrated) tends to be more reliable and easier to manage for group trips where multiple people need access.
When you open Airbnb's search filter panel, you'll see options for basic amenities like "Wifi" and "Pool." But for more specific features like Smart Lock, the filter may not appear at all — or it's buried so deep that most travellers never find it. Airbnb has assigned an internal amenity code to Smart Lock (code: 52), but their UI simply doesn't expose it.
This forces travellers into one of two bad options: read through every listing description hoping the host mentioned it, or book somewhere and discover the amenity isn't available after you arrive.
How CustomBNB Lets You Filter by Smart Lock
CustomBNB aggregates all of Airbnb's internal amenity codes — including Smart Lock (code 52) — and surfaces them through a simple, searchable interface. When you click the search button, CustomBNB generates an Airbnb URL with the amenity code appended, sending you directly to pre-filtered results on Airbnb's platform.
You're not leaving Airbnb's ecosystem — you're just arriving with your filters already set. CustomBNB requires no account to try, and takes under 30 seconds. For a deeper look at how Airbnb's hidden filter system works, read our complete guide to Airbnb's hidden amenity codes.

Tips for Booking an Airbnb with Smart Lock
Verify the Smart Lock before you commit
Airbnb amenities are self-reported by hosts. Before booking, scan the listing photos for the Smart Lock, check that recent reviews mention it positively, and read the "Things to know" section for any caveats. A filter match is a starting point — not a guarantee.
Message the host to confirm if it's a dealbreaker
If Smart Lock is essential to your trip, send the host a quick message before booking to confirm it's available and in working order for your dates. Most hosts respond within a few hours. Getting it in writing also protects you if there's a dispute after check-in.
What else to look for in the listing
Ask the host exactly how the code or app access is delivered, and when — some send it only hours before check-in, which is a problem if you're arriving very early or very late. Confirm whether the lock works without an internet connection or app, since a fully app-dependent lock can strand you if your phone dies or the property's wifi is down when you arrive.
