Enabling Digital Key with Your Phone

Open or download the latest version of the app on your phone.
Confirm you’re using the latest device operating system.
- Apple: iOS 26 (to confirm this, go to Settings > General > About)
- Android: Android 16 (to confirm this, go to Settings > About Phone)
Select the “Add key to device Wallet” home tile.
- If you don’t see this home tile, tap the More* icon (four circles) to access Vehicle Settings > Keys, then tap “Add key.”
* On some vehicles, you must tap the Settings icon (a gear) to access Vehicle Settings.
To continue, make sure:
- Bluetooth®* is turned on.
- Your phone and key fob are in the vehicle.
- Your vehicle is on and in PARK with the doors closed.
Follow prompts to pair your phone with digital key*.
When successful, your key will appear in your device’s wallet.
Verify that digital key* works by exiting the vehicle and using your phone to unlock, lock or start your vehicle without the key fob.

Using Digital Key

After you set up digital key*, you can use your phone or watch* in place of your key fob. Here’s how:

To lock or unlock your vehicle:

Approach with your phone and press the button on the door handle or pull the door handle (depending on your model)—just like you would if you had your key fob with you.
    — With Passive Entry enabled in the Settings menu, the digital key* will be detected when your phone is within 2 meters (approximately 6 feet) of the vehicle’s door.
        ■ This also allows you to unlock and open the liftgate with the exterior button (or hands-free on vehicles equipped with the kick-sensor radar that activates the Hands-Free Power Liftgate).
    — With Passive Locking enabled, the vehicle will lock approximately 8 seconds after you leave with your phone.
        ■ To receive an audible signal that your vehicle is locked, enable “horn chirp” in the Settings menu.

Note: Presence-based hands-free function (AutoSense Power Liftgate) currently requires the key fob to activate.

To start the vehicle:

Press the brake and then press the Power button.
In vehicles with no physical Power button, start the vehicle by pressing the brake pedal.

—In some cases, Hands-Free Start enables the vehicle to start when the driver’s door closes.

Remote Commands* (Lock, Unlock, Remote Start) with Digital Key

Access key features from your device’s mobile Wallet when within Bluetooth®* range of your vehicle (approximately 30 meters or 100 feet):

Go to your device’s wallet.
Tap the icons on your phone’s screen to perform each function:
- Lock
- Unlock
- Trunk: Opens the liftgate
- Climate: Remote starts your vehicle and preconditions the cabin temperature.

Sharing Keys

With digital key*, you can add recipients through your mobile Wallet app, enabling access for up to 3 people. Here’s how:

Open your device’s mobile Wallet.
Apple Wallet: Select the Share icon at the top-right corner of the digital key* screen.
Google Wallet: Select the Share button at the bottom of the screen.
Samsung Wallet: Select the symbol at the top of the screen that looks like a V turned sideways. Tap “Share key,” then “Set options and share.”
- You can also share by showing a QR code to the person receiving the key.
● When sharing via QR code, access options are preset and can’t be changed.
- Enter the name of the person you’re sharing with and select access options (not available when using the QR code).
- If options are available, you can toggle on the setting to require a first-time security code with key acceptance.
Choose a method of sending the digital key* to a friend, family member, or other trusted person—just like sharing photos from your phone.
- These methods depend on what’s installed on your phone and may include text message, email, Airdrop, etc.

Note: Digital key* recipients must have a UWB-compatible device. They don’t need the myCadillac mobile app* to receive the digital key.

Removing Keys

The account owner can remove their key as well as shared keys. Key recipients can only remove the key shared with them. Here’s how:

Go to the device’s mobile Wallet app and select “remove key.”
For Samsung Wallet, select “Delete” at the top right, then confirm by tapping “Delete” again when prompted.
Contact an OnStar®* Advisor by pressing your blue OnStar button or calling 888-4ONSTAR (888-466-7827).

If your device is lost or stolen, you may receive prompts to “remove owner key” and to initialize key pairing on the new phone.

Using Your Key Card as a Backup

While digital key* can be the primary way of accessing and starting your vehicle, you can use the key card that may be provided with your vehicle for valet parking or as a backup if your phone loses battery or is lost or stolen.

For best results, be careful not to place the key card on the wireless charging surface in your vehicle. Plus, keep it away from other charging devices, as they might interfere with the card’s functionality.

You must bring your physical key fob to all vehicle service visits.

Note: One key card may be provided to you along with your key fobs. You can purchase up to 7 additional key cards from your dealer. Your dealer can also deactivate lost cards to help prevent unauthorized vehicle access.

Q&As

HOW DO I ENABLE DIGITAL KEY?

To begin the digital key* journey, you must accept the OnStar Terms and Conditions and Privacy Statement, have connectivity in your vehicle, and download and/or sign in to the myCadillac mobile app*.

WHERE CAN I KEEP MY DEVICE TO ENSURE DIGITAL KEY WORKS BEST?

For the best experience using digital key* on a phone when approaching the vehicle, it's recommended to have the device in either your hand or front pocket rather than in a purse, backpack or back pocket.

When using digital key inside the vehicle, keep your device in the front seat (driver or passenger side) to help ensure optimal function.

HOW MANY DEVICES CAN I SHARE MY DIGITAL KEY WITH?

You can share your digital key* with up to 7 additional devices. Recipients aren’t required to have the myCadillac mobile app*, but their devices must be UWB-capable.

WHICH DEVICES ARE COMPATIBLE WITH DIGITAL KEY?

Some compatible devices are: iPhones starting with iPhone 11, excluding iPhone SE, XR and 16e, Apple Watch series 6 and beyond and Apple Watch Series Ultra 1 or newer; Google Pixel 6 Pro or newer, Google Pixel Fold and Pixel Watch 2 or newer (excludes Pixel “a” devices); Samsung Galaxy S21+, Galaxy Note 20+, Galaxy Z Fold2+ and Galaxy Z Trifold. A full list of compatible devices is included at the beginning of this article. As additional UWB devices are launched, this list will increase.

HOW SECURE IS DIGITAL KEY?

Your digital key* is stored on a “secure element” on your smartphone, which provides standardized hardware and software security. Ultra-wideband (UWB) technology also offers a secure connection that makes signals more difficult to intercept. Additionally, if your phone is lost or stolen, digital keys can be remotely removed, which can help prevent unauthorized access to your vehicle.

HOW CAN I AVOID LOCKING MYSELF OUT OF MY VEHICLE WHILE USING DIGITAL KEY?

Be aware that the vehicle will lock if more than one key device (phone, key fob or key card) is present and one of them leaves the vehicle. For example, if your passenger has a second key fob in their backpack, and both driver and passenger exit the vehicle, it is possible that the driver's phone and/or key card could be locked in if left in the vehicle.

To avoid a situation where you're locked out of the vehicle with no way of unlocking it, ensure that you always keep at least one key device with you when you exit the vehicle.

WHAT HAPPENS IF I LOSE MY PHONE?

If you lose your device, you can remove your key from your digital Wallet by contacting your device manufacturer. After you’ve removed the key, you can complete the setup process to add digital key* to another phone. If your vehicle is equipped with a key card, you can use it to access and start your vehicle. Refer to the back of your key card for the location of the exterior key card reader, which varies by model.

If you purchase a new phone, you’ll receive prompts to remove your key and transfer it to the new phone.

HOW DO I REMOVE MY DIGITAL KEY?

You can remove a digital key* 2 ways:

From the device's mobile Wallet app, select "remove key” or “delete,” depending on your device.
Contact an OnStar Advisor at 888-4ONSTAR (888-466-7827) or by pressing the blue OnStar button.

Recipients of shared keys can only remove the key that’s been shared with them.

HOW DO I GET ALL MY DOORS TO UNLOCK WITH DIGITAL KEY?

Within the vehicle’s center display, navigate to Settings > Remote Lock*, Unlock* and Start* > Unlock Options. Under "Passive Door Unlock," there will be an option for “All Doors” or “Driver Door.” Select “All Doors” to enable all doors to unlock when you approach the vehicle with your digital key*.

HOW DO I GET MY DOORS TO LOCK WHEN I WALK AWAY?

First, turn on "Passive Door Lock" in your vehicle’s settings. Next, make sure the vehicle is turned off and every door, as well as the trunk, hood and tailgate, is fully closed. Then, when you walk away from the vehicle carrying your digital key*, the doors should lock.

If a door or closure is open, the system will not lock the vehicle automatically. Ensure you have “horn chirp” enabled as it will also be an indication for locking.

CAN I LOCK MY VEHICLE WITH DIGITAL KEY IF THE KEY FOB IS INSIDE?

Yes, you can securely leave your key fob inside the vehicle and lock it by walking away with your digital key*.

HOW DOES DIGITAL KEY DIFFER FROM THE REMOTE COMMANDS IN THE MYCADILLAC APP?

Digital key* allows you to perform some of the same short-range remote commands that are available in the mobile app* (climate, lock/unlock) when you’re within Bluetooth* range of the vehicle. The main differences are:

With digital key, these functions are accessed through the Wallet of your paired device.
Users of digital key can drive the vehicle without needing the key fob. This function is not available in the mobile app*.

CAN THE DIGITAL KEY OWNER RESTRICT FUNCTION FOR A SHARED KEY?

Yes, the key owner can set the shared key to only be capable of locking/unlocking the vehicle. In this case, the recipient would not be able to start the vehicle with their shared key.

CAN I USE DIGITAL KEY TO ACTIVATE MY AUTOSENSE POWER LIFTGATE?

No. The hands-free liftgate function can only be activated with digital key* in vehicles equipped with a kick-sensor radar (Hands-Free Power Liftgate).

CAN I USE VALET PARKING SERVICES WITH DIGITAL KEY?

Yes. For valet parking with digital key*, simply give the valet attendant your key card, the same way you would a key fob.

DOES USING DIGITAL KEY IN COMBINATION WITH THE BACKUP KEY CARD REPLACE MY KEY FOB ENTIRELY?

No. There are certain instances when you will have to use your key fob instead of digital key* or the key card. For example, it’s important to always bring the key fob to your vehicle’s service visits. This ensures technicians can properly access the vehicle.

WILL MY DIGITAL KEY STILL WORK IF I TAKE MY VEHICLE ON A TRIP?

Yes, your digital key* will work with your vehicle when you're out of town or on vacation. Please note that if it has been more than 10 days without interaction with your vehicle, you may have to "wake" the vehicle. Simply pull the door handle and press the small rectangular button on the door handle (if there is one). The vehicle will then connect with your device.

CAN I CONNECT A PROFILE TO MY DIGITAL KEY?

No.

CAN I CONNECT WITH OTHER VEHICLE FEATURES USING DIGITAL KEY, SUCH AS MEMORY SEATS OR TEEN DRIVER?

No. At this time, digital key* does not connect with any vehicle features beyond those included in this article.
