Access your car, home, workplace, and hotel room with keys in Wallet on Apple Watch
In the Wallet app 
on your Apple Watch, you can store keys to your car, home, and hotel room.
Unlock and start your car (Apple Watch Series 5 and later)
Unlock, lock, and start your car just by being near a compatible car. Ultra Wideband provides precise spatial awareness, ensuring that you won’t be able to lock your iPhone or Apple Watch in your car or start your vehicle when iPhone or Apple Watch isn’t inside.
To add car keys to your Apple Watch, follow these steps:
Add the car keys to the Wallet app on the iPhone that’s paired with your Apple Watch.
Open the Apple Watch app on your iPhone.
Tap My Watch, then tap Wallet & Apple Pay.
Tap Add next to the card for your car key.
To unlock and start your car, do one of the following:
Apple Watch Series 5: Hold your Apple Watch near the car’s door handle to unlock it. Hold your watch near the car’s key reader, then press the car’s start button.
Apple Watch Series 6 or Apple Watch Series 7: If you have a car that supports Ultra Wideband technology, approach your car while wearing your Apple Watch to unlock it. Press the car’s start button to start the car.
Note: If the car doesn’t support Ultra Wideband technology but can use a car key stored in the Wallet app, unlock and start the car just as you would with Apple Watch Series 5 or later.
See the Apple Support article Use your iPhone or Apple Watch as a car key.
Unlock your home
Some lock makers provide the ability to unlock your door with a home key in Apple Wallet on your compatible iPhone and Apple Watch (Series 4 and later). You add a home key to Apple Wallet with the Home app on your iPhone.
When you have a home key on your iPhone or Apple Watch, just place your device near the lock to unlock it. You can use the Home app to share access with other people.
To set up a home key, follow these steps:
Add the lock to the Home app on your iPhone.
Choose an unlocking option.
Express Mode: Unlock the door just by holding your iPhone or Apple Watch near the lock.
Require Face ID or Passcode: Hold your device near the lock, then use Face ID or Touch ID to unlock it.
Choose automations such as Lock After Door Closes and Lock When Leaving Home.
If the lock you add supports HomeKit, all residents of your household receive the home key automatically.
See Unlock your door with a home key on iPhone in the iPhone User Guide.
Access your workplace
If you work at a participating corporate office, you can add your corporate access badge to the Wallet app. To access locations where your badge is accepted, place your iPhone or Apple Watch near the badge reader.
Unlock your hotel room
You can add a hotel key to Wallet from the participating hotel provider’s app, use it to check in without going to the lobby, and use your iPhone and Apple Watch to unlock your room. Wallet automatically archives your pass after you check out to keep passes organized as you travel.
