Apartment Buzzer for Airbnb & Short-Term Rental Hosts

If you host an Airbnb, VRBO, or short-term rental in an apartment building with an intercom, guest access is one of the hardest parts to get right. Your building's buzzer calls a phone number. Someone has to answer. And that someone is usually you — at midnight, during dinner, or while you're across town.

The Airbnb buzzer problem

Traditional apartment intercoms are designed for residents who live there full-time. They assume the person being buzzed is home, available, and knows who's at the door. Short-term rentals break all three assumptions:

• Guests arrive at unpredictable times — late flights, early check-ins, middle-of-the-night arrivals
• You're often not in the building when guests arrive
• Guests don't know how to use the intercom (which button, which unit number)
• You don't want to give your personal phone number to every guest
• Multiple guests may arrive at different times during the same stay

Current solutions and their limitations

Lockboxes and smart locks

Smart locks on the unit door solve access to the apartment itself, but not the building entrance. If your building has a locked front door with an intercom, a smart lock on unit 4B doesn't help someone standing at the street-level entrance. You need both: building access and unit access.

Sharing your phone number

Some hosts give guests their personal cell so the guest can call when they arrive and the host can press 9. This works but means you're on-call 24/7. You also end up with guests calling you for non-buzzer reasons, and your personal number is exposed in the Airbnb message thread.

Access code buzzer apps

Some buzzer apps like FreshBuzzer and Ringo let you create PIN codes that guests enter when they call the intercom. This works but requires the guest to remember a code, navigate an automated phone menu, and enter digits correctly — a surprisingly high-friction experience for tired travelers.

How BuzzBot handles short-term rental access

BuzzBot uses spoken passcodes instead of keypad PINs. Before the guest arrives, you create a passcode in the app — a label like "Airbnb Oct 15–18" and a short secret phrase like "North Star" or "blue elephant." You share the phrase with the guest in your check-in message (the same way you’d share a PIN). When the guest buzzes, BuzzBot asks who’s there, the guest says the phrase, and the door opens.

It’s the same concept as a PIN, but over voice instead of keypad. The passcode is a per-guest (or per-booking) secret you control from the app, not an identity match against a name list.

The flow for a guest arriving at your Airbnb:

• Guest presses your unit number on the intercom
• BuzzBot answers and listens, with English and Spanish prompts
• Guest says the passcode phrase you gave them
• BuzzBot matches the phrase against your active passcodes
• Door opens automatically
• You get a push notification showing which passcode was used

Setting up BuzzBot for Airbnb hosting

• Download BuzzBot and give your building the BuzzBot number (one-time setup)
• In Settings › Secret Passcodes, create a passcode for each booking: a name like "Sept 12 guests" and a phrase like "watermelon"
• Include the phrase in your Airbnb check-in message alongside the unit number and WiFi password
• Delete the passcode after checkout, or leave it and replace it next time — you can keep up to 20
• For cleaning crews and co-hosts, create a permanent passcode (e.g., "house keeper") that never expires

BuzzBot costs $3.99/month or $39.99/year after a $1.99 trial — less than a single lockbox replacement.

Common hosting scenarios

Late-night arrival

Guest’s flight lands at 11 PM. They arrive at your building at midnight. They say the phrase from your check-in message. BuzzBot matches it against your active passcodes and opens the door. You’re asleep and never need to be involved — you see a push notification in the morning telling you which passcode was used and at what time.

Multiple guests arriving separately

A group of three friends booked your place and they’re arriving at different times. You don’t need a passcode per person — one passcode for the booking is enough. Share the same phrase with all three, and each one gets buzzed in independently when they say it.

Cleaning crew between guests

Create a permanent passcode for the crew (e.g., label: "Cleaning," phrase: "polish"). They use it every cleaning day without you being involved. It’s separate from the guest passcode, so you can see in the activity feed whether a buzz came from the cleaner or a guest.

Non-English-speaking guests

BuzzBot prompts callers in English and Spanish. The passcode itself is language-agnostic — a phrase like "North Star" or an easy word in the guest’s own language works equally well, because the match is against the literal phrase you registered, not a language model.

Spoken passcodes vs. keypad PINs

Both are shared secrets. The difference is the input channel. A keypad PIN requires the guest to listen to an automated prompt, remember the number, and enter digits in the right order during a live call — at midnight, on a noisy street, often with luggage in one hand. A spoken passcode just requires the guest to say the phrase. Speech-to-text handles accents, mumbling, and surrounding words ("uh, it’s ‘watermelon’") gracefully.

Security is comparable. Both are shared secrets that a guest could in theory pass to someone else. The mitigation is the same in both cases: rotate the secret between bookings. BuzzBot lets you delete a passcode in one tap, so you can cycle the phrase per booking if you want.
