BMW Digital Key Setup: How to Use Your iPhone or Apple Watch as a Car Key | Ditch the Fob, Keep the Freedom
Picture this: You’re rushing out the door, hands full of coffee and work bag, and you realize your BMW key fob is somewhere in the abyss of your couch cushions. With BMW Digital Key, that moment of panic becomes a thing of the past. Your iPhone or Apple Watch can now unlock, start, and even share your car with others—no physical key required.
TL;DR: BMW Digital Key lets you use your compatible iPhone or Apple Watch as a fully functional car key. Set it up via the My BMW App, store it in your Apple Wallet, and use it to lock, unlock, and start your vehicle using Near-Field Communication (NFC) technology. With Digital Key Plus, you don’t even need to take your phone out of your pocket—just walk up and the car recognizes you. You can also share digital keys with up to 5 friends or family members and set driving restrictions for safety .
Key Takeaways
- No physical key needed: Unlock and start your BMW using just your iPhone or Apple Watch .
- Express Mode works even with a dead battery: Your iPhone can still unlock and start the car for up to 5 hours after the battery dies—Apple Watch users, take note, this feature isn’t available for you yet .
- Digital Key vs. Digital Key Plus: Standard Digital Key requires you to hold your device near the door handle. Plus uses ultra-wideband technology to unlock the car automatically as you approach .
- Share keys with ease: Send a digital key to up to 5 people via Apple Wallet. You can also set speed limits or restrict vehicle functions for young or inexperienced drivers .
- Wear it on your wrist: If your iPhone has an active Digital Key, it syncs automatically to your paired Apple Watch Series 5 or newer. Just hold your watch near the door handle to unlock .
- Must-have prerequisites: Your BMW must have the Comfort Access package, you need iOS 13.6 or newer, and you’ll need your physical key fob (yes, both of them!) for the initial activation .
What Exactly Is BMW Digital Key?
BMW Digital Key replaces your traditional key fob with a secure digital version stored in your Apple Wallet. It uses NFC technology—the same stuff that powers Apple Pay—to communicate with your vehicle . When you hold your iPhone or Apple Watch near the door handle, the car recognizes the encrypted key and unlocks the doors. Place the device on the wireless charging tray inside the car, and you can start the engine just like you would with a physical key .
Think of it as Apple Pay, but for your car.
Digital Key vs. Digital Key Plus: What’s the Difference?
This is where things get interesting. BMW offers two flavors of digital keys:
| Feature | BMW Digital Key | BMW Digital Key Plus |
|---|---|---|
| Availability | Vehicles from July 2020 onward | Vehicles from July 2021 onward |
| Unlocking method | Hold device near door handle (NFC) | Automatic recognition as you approach (UWB) |
| Starting the car | Place device on wireless charging tray | Device stays in pocket or bag—just get in and drive |
| Passive entry | No | Yes—welcome lights and unlock happen automatically |
| Device requirement | iPhone 11 or newer (varies) | iPhone 11 or newer (SE models excluded) for passive entry |
“Your BMW welcomes you as soon as you approach the vehicle. This function switches on the lights, starts a welcome animation and unlocks the doors.”
If you have a newer BMW with Digital Key Plus, you’ll experience something almost magical: the car senses you walking toward it, turns on the welcome lights, unlocks the doors, and loads your personal BMW ID profile settings—all without you pulling out your phone .
