Frequently asked questions about SoundKey

With any intercom or video intercom whose door-release button is a physical push button (it goes down when you press it): analogue, digital 2-wire and video intercoms from Fermax, Tegui, Golmar, Comelit, Urmet, Bticino, Auta and other brands. See the list by brand.

Not yet: compatibility with touch buttons and touch screens is in development. If your intercom has touch controls, join the waitlist and tell us; we'll let you know as soon as it's ready.

Nuki Opener and Ring Intercom mimic the intercom's electrical signals, and in 2-wire systems each manufacturer uses its own protocol. SoundKey doesn't mimic signals: it presses the door-release button. More details.

A version that lifts the handset automatically is in development. Mention it when you join the waitlist so we can let you know.

In the app you tap “Open” or switch SoundKey on for the next few hours. When the person rings the intercom, SoundKey hears the buzzer and opens the door. That way the door never opens with nobody in front of it.

Yes. In the app you create a link for that person (family, cleaner, a guest) and choose whether it works always, between two dates or only on certain days and hours. When they arrive, they open the link on their phone, tap “I'm about to ring” and ring the intercom: the door opens. You can turn the link off whenever you like. Every booking already has its own.

No. Only when you've switched it on or during a booking's arrival window. The rest of the time the intercom works as usual.

If it was already opening for an arrival, it keeps opening until that window ends. To switch on new openings it needs a connection. Your intercom and your keys keep working as always.

A normal 2.4 GHz WiFi network, the one at home or in the holiday let. Setup is done from your phone in a couple of minutes.

The app shows every time the buzzer has rung and every opening, with the time, as well as the battery level and WiFi signal.

You open the cover of the intercom in your flat and connect two wires to the door-release button's contacts; on some models they need to be soldered. SoundKey sits next to the intercom, in its own case. No building work and no new intercom.

No. It has a rechargeable lithium battery and charges over USB-C, like a phone.

We're measuring real battery life on devices running every day. We'll publish the figures once testing is finished, rather than quote a number we haven't verified. The app warns you when the battery is low.

SoundKey is installed on the intercom in your own home, without touching the building's shared installation, and does the same as pressing the door-release button. If your community of owners has its own rules on access, it's worth checking with them.

It's not on sale yet. The planned price is €10 a month with the device included and a 12-month minimum term, plus the GoToCheck.pro Premium plan free for the first year. It may change before launch.

GoToCheck.pro is our online check-in and guest registration software for holiday rentals, made in Granada.

With SoundKey you get it free for the first year.

Yes: the service includes the device, the app, the connection to your reservations and updates. In return, you don't pay for the device.

It's a fair question: other door openers such as Nello stopped working when their company closed. Your intercom never stops working, because SoundKey is simply added to the button.
