To use a Marriott mobile key, open the Marriott Bonvoy® Mobile Application, tap the "Mobile Key" button located just under the image on the screen, and hold your device near the door lock. This digital key replaces a physical key card for your room and common areas at participating properties, making your stay more seamless and contactless.
What is a Marriott mobile key?
A Marriott mobile key is a digital feature within the Marriott Bonvoy® Mobile Application that allows you to unlock your guest room and access common areas using your smartphone instead of a traditional plastic key card. It uses Bluetooth technology to communicate with door locks, elevators, fitness centers, and parking garages, providing a convenient and secure way to move through the hotel without stopping at the front desk.
Check if your hotel offers mobile key
Mobile Key is only available at select participating Marriott properties. To verify availability before booking or arrival, open the Marriott Bonvoy® Mobile App and navigate to the hotel's details page. Look under "Property Details" or "Key Amenities." Alternatively, on the Marriott website, check under "Featured Amenities on Site" then "Property Details." If Mobile Key is listed, you can use it for your stay.
Download the app and sign in to your Bonvoy account
You must install the Marriott Bonvoy® Mobile Application on your smartphone and be logged into your Marriott Bonvoy® Account to receive your key. This is one of the most essential mobile apps you must download in 2022 for a frictionless hotel experience. Ensure the Bonvoy account number linked to your reservation is the same one you use to sign in, as that number must be on the reservation for Mobile Key to work. Your Marriott Bonvoy® Account Number must be on the reservation to enable Mobile Key use.
Enable Bluetooth and trip notifications
Two critical settings must be active for your mobile key to function. First, Bluetooth must be enabled on your mobile device, because the app uses it to communicate with the door lock. Second, trip push notifications must be turned on under the "Communication" settings in the Marriott Bonvoy® Mobile App. These notifications alert you when your key is issued and when your room is ready, ensuring a seamless experience.
Request your mobile key before arrival
Your mobile key generally becomes available within two days of your arrival. Mobile Key generally becomes available within two days of your arrival. You will receive a push notification confirming its issuance once your room is ready. In certain regions, Multi-Factor Authentication (MFA) may be required to request a Mobile Key, involving a one-time verification code via email or SMS. Complete this step promptly so the key is active when you arrive.
Use your phone to unlock your room and common areas
When you reach your door, open the Marriott Bonvoy® Mobile Application and tap the "Mobile Key" button just under the image on the screen. Hold your device near the door lock until the door unlocks. Mobile Key can open any door normally accessed with a physical key card, including your room and common areas such as elevators, fitness centers, and parking garages. Note that this process is unrelated to unlocking carrier phones from Verizon, AT&T and T-Mobile; it is a dedicated hotel access feature.
Share your mobile key with other guests
The primary guest on a reservation with an active Mobile Key can share digital access with up to three additional registered guests. To share a key, open the Marriott Bonvoy® Mobile App, tap the "Key" icon, select the "Share Key" button on the Mobile Key screen, and choose the Registered Guest from the list. Guests receiving a shared key must be 18 or older, Marriott Bonvoy® Members, have the Marriott Bonvoy® Mobile App installed, and be registered on the reservation. Each registered guest can only hold one active Mobile Key at a time across the entire Marriott portfolio.
Check out and what happens to your key
You can check out digitally through the app to settle your bill and bypass the front desk. After checkout, all shared and primary mobile keys automatically expire. All shared keys automatically expire at checkout. This ensures no one can access your room after your stay ends, and the digital key is removed from your device.
Troubleshooting and backup options
If your mobile key is not working, first ensure Bluetooth is enabled on your device and that trip notifications are on. Close and reopen the app to refresh the connection. If the issue persists, you and your guests can still request traditional physical key cards from the Front Desk at any time, even if you are using Mobile Keys. Physical cards are always available as a reliable backup.
