Why Smart Locks Are Essential for Airbnb
Handing off physical keys is one of the biggest operational headaches in short-term rentals. Guests lose them, arrive at 2am when you're asleep, or check out without returning them. I've seen hosts spend $150 rekeying a property after a single lost key incident. Do that twice and you've already paid for a decent smart lock.
Beyond the cost, the bigger issue is the guest experience. Listings with self check-in consistently outperform those without it on Airbnb. Guests prefer flexibility. They don't want to coordinate their airport delay with your schedule. A smart lock solves that problem entirely.
If you're serious about running your property like a business, keyless entry is non-negotiable.
Best Smart Locks for Airbnb by Budget
Not every property needs a $300 lock. Here's what I actually recommend at different price points.
Budget Pick: Wyze Lock Bolt ($80-90)
The Wyze Lock Bolt is fingerprint and keypad entry, no subscription required. For hosts who want to get off physical keys without spending much, this is a solid starting point.
The downside: no Wi-Fi on the base model, which means you can't change codes remotely without a separate hub. For a single property you manage yourself and visit regularly, that's workable. For remote management, it becomes a problem fast.
Mid-Range Pick: Schlage Encode Plus ($200-230)
This is what I'd put on most properties. The Schlage Encode Plus has built-in Wi-Fi, no hub required, and works natively with Apple Home. It holds up to 100 access codes, has a solid build quality, and Schlage has been making locks for over 100 years. The thing feels substantial when you touch it.
The Encode Plus also supports HomeKit, which matters if you're building out any smart home integration. Code changes take about 10 seconds from your phone. For a host managing 3-5 properties, this is the right tool.
Premium Pick: Yale Assure Lock 2 with Wi-Fi ($240-270)
The Yale Assure Lock 2 is what I recommend when hosts ask me about integrating with property management software. It plays well with most major platforms: Hospitable, Guesty, OwnerRez, and others. You can set codes to auto-generate and auto-expire based on your booking calendar, which eliminates nearly all manual code management.
It's also one of the cleaner-looking locks available, which matters more than people admit. A bulky lock on a nice front door sends a subtle signal that the host is winging it.
Also Worth Considering: August WiFi Smart Lock ($200-220)
August works differently from the others. It installs on the inside of your door and uses your existing deadbolt. That makes installation faster (15 minutes, no tools needed beyond a screwdriver) and it preserves the exterior look of your door. If your HOA restricts exterior modifications or you're in a rental yourself, August is often the cleanest solution.
The tradeoff: it's less robust than a full deadbolt replacement, and the battery life can be annoying to track.
Code Management Best Practices
The hardware is the easy part. Where most hosts make mistakes is in how they manage codes.
Use unique codes per guest, not a rotating monthly code. I've seen hosts use the same 4-digit code for months. If a guest takes a photo of it, writes it down, or shares it, you've permanently compromised your access. With Schlage or Yale, generating a new code takes 20 seconds.
Set expiration times that match checkout. If checkout is 11am, the code should stop working at 11am. Not noon, not "sometime that day." This creates a clear boundary and prevents ex-guests from wandering back in during your cleaner's window.
Never use obvious codes. 1234, 0000, or the last four digits of your phone number are not secure. I use a random 6-digit generator and paste it into my messaging platform. No pattern, no logic.
Keep a master code. This is a permanent code only you know, different from guest codes. Your cleaner can have their own separate code too. Don't mix these up or share the master code with guests.
A clean code structure looks like this:
- Master code (owner only, permanent)
- Cleaner code (permanent, 4-6 digits, different from master)
- Guest code (unique per booking, expires at checkout)
- Maintenance code (temporary, delete after each use)
Backup Entry Methods
No matter how reliable your lock is, you need a backup plan. Technology fails. Batteries die. Guests will arrive after a long flight with a dead phone and no code written down.
Keep a lockbox nearby with a physical key. Not visible from the street, not under the mat. I prefer a combination lockbox mounted somewhere discrete, like inside a fence or behind a planter. Give guests the lockbox code only if the smart lock fails. Don't lead with it.
Have a local contact. This could be a neighbor you trust, a property manager, or a co-host. Someone who can physically be at the property within 30-45 minutes if there's a genuine lockout. Post this person's number in your house manual and in your automated messages.
Check battery levels before every check-in. Most smart locks send low-battery alerts through their app. I check battery status as part of my pre-check-in routine, same day or day before arrival. A dead lock battery is a 5-star review killer. Schlage and Yale locks typically run 6-12 months on AA batteries with normal use.
Test the code yourself before messaging it to guests. This takes 30 seconds and prevents the most common lockout scenario: a host who set the code wrong and didn't realize it.
Integration with Property Management Software
If you're managing more than two or three properties, manual code management will eat your time. The better approach is connecting your smart lock to a property management system (PMS) that auto-generates and auto-expires codes based on your reservation calendar.
The Yale Assure Lock 2 and the Schlage Encode Plus both integrate with most major platforms. Hospitable (formerly Smartbnb) has solid lock integration for hosts running a smaller portfolio. Guesty and OwnerRez are better for larger operations.
When it's set up correctly, here's what happens automatically:
- A reservation is confirmed on Airbnb
- The PMS generates a unique access code
- The code is pushed to the lock and added to your pre-check-in message template
- The code expires at the checkout time on the booking
No manual steps. No risk of accidentally giving a guest last month's code. I've seen hosts save 3-4 hours per week once this is running properly, and that's not a stretch for someone managing 8-10 properties.
If you're not ready for a full PMS, most smart lock apps have basic scheduling built in. It's more manual but still better than physical keys.
How to Write Guest Instructions That Actually Work
Even a perfectly set-up smart lock will generate support messages if your instructions are unclear. I've dialed this in over hundreds of check-ins.
Your check-in instructions should include:
- The exact lock location. "Front door" is not enough. "The black keypad lock on the main entrance door facing the parking lot" is better.
- Step-by-step entry sequence. For most keypads: press the Schlage button to wake the keypad, enter your 6-digit code, press Schlage again. Write it out exactly like that.
- What to do if it doesn't work. One sentence: "If the code doesn't work, text me at [number] and I'll respond within 10 minutes."
- Checkout instructions. Guests often forget to lock the door. "Pull the door closed and press the lock button on the keypad" is clearer than "please lock up."
Send these instructions the day before check-in, not at time of booking. Guests skim booking confirmation messages. A day-before message gets read.
One more thing: take a photo of the lock from the guest's perspective (standing at the door) and include it in your instructions. This sounds minor but it eliminates a surprising number of "I can't find the lock" messages.
These recommendations work for most properties, but the right lock setup depends on your specific situation. A single condo in a managed building has different constraints than a standalone cabin 40 minutes from town. And the lock is just one piece of your listing's overall guest experience.
If you want someone to look at your full listing setup and give you specific feedback on your check-in process, photos, description, and pricing, a STRAudits listing audit costs $49 and comes back in 48 hours. It's the fastest way to find out what's actually holding your listing back.
