Protobuzz is your ultimate solution for seamless and automated entry management. With Protobuzz, users can effortlessly automate and schedule buzzer activities to grant access to visitors, deliveries, and guests right from their smartphones. Whether you're managing a residential building, office space, or gated community, Protobuzz revolutionizes the way you handle entry permissions. A Protobuzz Subscription is required in order to get a buzzer number assigned and to schedule it as needed. Alternatively, if you are joining a group with an existing Protobuzz Subscription, you can have another member of the group share the Group Invite Code with you. This code would be entered as part of the setup process instead of subscribing to a new buzzer number.

Enterkey is an apartment buzzer app. Your building's existing buzzer or intercom dials a virtual phone number Enterkey gives you, and Enterkey answers: timed keys let couriers and guests in automatically, PINs keep it secure, schedules cover the same hours every week, and your whole household can answer from anywhere. No hardware, no installer, one directory change by your property manager. HOW IT WORKS Sign up and Enterkey gives you a local virtual number near your own. Ask your property manager to point your unit's buzzer entry at that number. Buzzes now ring your phone as usual, and whenever a key is armed, Enterkey answers and opens the door for you. WHAT YOU CAN DO • Timed keys: arm the buzzer for 5, 15, 30 or 45 minutes, or 1, 2, 4, 8 or 12 hours. When the courier buzzes, the door opens without a call. • Permanent keys with a PIN: a standing code for the dog walker, the cleaner or the nanny, protected by a PIN they type or say at the panel. • Recurring schedules: the same window every day, on weekdays, weekends or the days you pick. • Shared household access: invite roommates and family with a link. Every buzz rings every phone, and anyone can let a visitor in. • Activity log: see the time of every entry and which key or schedule opened the door. • Welcome message: record a short greeting that visitors hear at the panel (one-time add-on). • Custom incorrect-PIN message: tell a visitor what to do if they get the code wrong. MADE FOR • Package and food delivery: Amazon, UPS, DoorDash, Uber Eats, SkipTheDishes and every other courier who has ever driven off with your order. • Hosting: arm a key for the evening and stop working the door at your own party. • Roommates and family: one buzzer that rings everyone. • Short-term rental guests, caregivers, cleaners, pet sitters, home-office clients, and kids getting home before you. WORKS WITH YOUR BUILDING Enterkey works with any buzzer, intercom, call box or telephone entry system that dials a phone number, including Mircom, Enterphone, TekTone, Linear, DoorKing and Aiphone models. It does not work with systems wired to an in-unit handset that never dials out. Available across Canada and the United States. PRICING New members get their first month free. After that, Enterkey Pro is $9.99 per month or $69.99 per year (about $5.83 a month), and covers your whole household. One building per account. Cancel anytime in your Apple ID settings before the trial ends, and you won't be charged.
