JustIN Mobile user guide

Overview

Salto's JustIN Mobile technology allows you to use your phone as your key. The intuitive Salto JustIN Mobile app securely enables you to receive your key online, anytime and anywhere. When you arrive, for example, at a hotel, you can choose to go straight to your room and receive the room key on your phone, or you can ask for assistance at reception. It's your choice.

No key assigned

If no key has been assigned to your telephone number, the following message will display:

"This number has no key assigned to it. Contact your key issuer to receive a key. Your key issuer could be the hotel or apartment you're staying at, or the company whose office or building you're visiting."

The above message displays if you do not have a key assigned to your phone number

If you see this message, please check with the person or entity who issued your key. As previously stated, this could be the hotel or apartment you're staying in, or it may be the company you work at, or an office building, hospital or university you're visiting. You should also check that the phone number you enter is correct and that it corresponds to the phone number held by the key issuer in your name.

Key assigned

If your phone number does have a key assigned to it, the verification screen will be displayed. The verification code is sent to your phone via a text message. Enter it in the verification screen. Once verified, JustIN Mobile will be launched.

About JustIN Mobile keys

This section describes the following JustIN Mobile features:

• Phone number change
• Key cancelation
• Getting keys
• Using keys

Phone number change

See What happens if I change my phone number? for information about what to do in case you change your telephone number.

Key cancelation

If your key issuer cancels your key, you will no longer see it in JustIN Mobile, but you will still be registered in the app. However, the key list screen will be empty and will show a message informing you that no key is assigned to you.

Getting keys

Once the phone number verification process has finished, you will receive the key that's been assigned to you.

• Getting keys automatically

If push notifications are enabled for the app, keys will be sent automatically whenever a notification is issued by the cloud. You don't need to perform any further action. All the keys available will be displayed in the key selection screen. To use any of the keys available, refer to Use of keys.

Key notification example

• Getting keys manually

Instead of just waiting for keys to arrive, users can also explicitly request to check if there are any new keys available. To do so, swipe the list of keys from top to bottom. This method will be the only way to receive new keys if push notifications aren't enabled.

Swipe down to check if there are new keys available

Locking

After unlocking a door, most Salto locks will automatically lock again after around 6 seconds. You don't need to use the JustIN Mobile app to lock the door.

The exact timing may vary depending on your specific lock model.

Opening modes and locking behavior

The locking behavior may also depend on whether an opening mode has been applied to the lock. See the section on opening modes for more information about opening modes and their effect on locking behavior.

NFC unlocking

You can unlock doors using NFC without opening the app. Your phone must have NFC activated and be unlocked. Where possible, we highly recommend using this way of unlocking if your device meets the requirements indicated in the above table.

When unlocking with NFC and using an iPhone, make sure to hold your phone close to the lock's reader, as indicated in the screenshot below.

The iOS app includes a short animated tutorial on how to unlock with NFC

!iOS NFC unlocking options:

1. Side button/Action button method (Recommended for iPhone 15 Pro and later, also requires minimum iOS 18):

   • Similar to making a payment with Apple Pay
   • You can configure the Action button through Control Center

2. Control Center customization:

   • Customize through iPhone's Control Center settings
   • Add JustIN as a control for quick access

Language

The JustIN Mobile app is available in several different languages. The way you change the language of the app interface depends on your device's operating system.

Changing the language in iOS

For Apple devices, you can change the language of the app independently from the default language of your device's operating system.

To do so, go to your device's Settings app, select JustIN Mobile > Preferred Language and choose the desired language of the app.

Changing the language in Android

For Android devices, the app automatically detects the default language of your device. If your language is not supported in the app then the app will display in English.

To change the language of your Android device go to Settings > System > Languages & input > Languages.

This process may be different for specific models of Android devices.
