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 answers your apartment buzzer for you. When a courier or a friend buzzes, Enterkey can open the door, so you don't have to pick up and press 9. No hardware, nothing to install. Free for 14 days. HOW IT WORKS, IN 3 STEPS 1. Sign up. Enterkey gives you a phone number for your apartment. 2. Ask your property manager to point your buzzer at that number. It takes them a few minutes. 3. Make a key, like "Courier". Turn it on before a delivery. When the driver buzzes, the door opens. When no key is on, the buzz rings every phone in your home, the same as today. WHAT'S A KEY? A key tells Enterkey who to let in, and when. Turn one on for 1 minute up to 24 hours, give it a PIN for people you trust, or set it to turn on by itself at the same times every week. WHAT YOU CAN DO • Timed keys: turn a key on for any length from 1 minute to 24 hours. When the courier buzzes, the door opens without a call. • PIN keys: a standing key for the dog walker, the cleaner or the nanny, protected by a PIN they type at the panel. • Schedules: a key that turns itself on and off at the same times every day, on weekdays, weekends or the days you pick. • Your whole household: invite roommates and family with a link. Every buzz rings every phone, and anyone can let a visitor in. • Activity: see the time of every entry and which key opened the door. • Welcome message: a short greeting 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 • Deliveries: Amazon, UPS, DoorDash, Uber Eats, SkipTheDishes and every courier who has ever driven off with your order. • Hosting: turn a key on for the evening and stop running to the door at your own party. • Roommates and family: one buzzer that rings everyone. • Short-term rental guests, caregivers, cleaners, pet sitters 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. 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 14 days 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.

Verdict

The call

The clearest difference is rating: Protobuzz at 5.0 against Enterkey's 4.2. Protobuzz also leads on review sentiment (100% vs 84%) and iOS requirement (13.0 vs 15.0). Enterkey's advantage is monetization model (freemium vs subscription) and update cadence (every 3 days vs weekly). On price, ads, in-app purchases and device support there is nothing between them.
