Remember when buying a new car meant getting two sets of keys? It was a small reassurance—a backup for forgetfulness, a courtesy to your partner, or just a symbol of ownership. But for MINI, that tradition is being phased out. As of 2025, all new MINI models—Cooper, Countryman, Aceman—will ship with just one physical key fob.
At first glance, it seems like a corner-cutting cost reduction. But there’s more to the story. MINI isn’t just subtracting a second key; it’s replacing it with something more modern, more secure, and—if it works right—more convenient. It’s called Digital Key Plus, and it’s quietly reshaping how you unlock, start, and share your MINI.
This isn’t just a gimmick. It’s a shift in how MINI expects owners to interact with their cars—less mechanical, more digital. And while some might bristle at the change, the technology has matured to the point where it’s actually… good. For instance the NFC powered CarKey function will work for up to five after after your iPhone is dead.
Let’s take a look at what’s behind MINI’s move, what you lose by giving up that second fob—and what you gain.
According to MINI representatives, the brand’s decision to eliminate the second physical key across the lineup isn’t intended to punishing buyers and simply save cost—it’s about how people use their cars today.
According to MINI, most owners never touch the second key. It sits in a drawer or glove box until the first one goes missing. Meanwhile, the cost of producing that second fob—north of $300 when you factor in hardware, software, and coding—is passed on to every buyer whether they use it or not.
There’s also the environmental and supply chain angle. Cutting production of redundant electronics means fewer raw materials and less e-waste. In a world where sustainability plays into brand identity as much as design or performance, that matters.
But the biggest reason for the shift is confidence in a replacement: the smartphone in your pocket.
This isn’t MINI’s first run at phone-based key access. But with Digital Key Plus, the system finally feels fully realized.
Using Ultra Wideband (UWB) and secure NFC, Digital Key Plus knows where you are—literally. It doesn’t just detect that your phone is nearby; it knows whether you’re standing outside the driver’s door or sitting behind the wheel. That precision allows for true passive entry and start. No buttons. No unlocking apps. Just walk up, get in, and drive away.
The system works with iPhones (XS or newer) and a growing list of Android phones that support UWB. Setup is handled through the MINI app and your phone’s wallet (Apple Wallet or Google Wallet), and once configured, your phone becomes a full-function key.
You can also share access with others—send a digital key to a partner, friend, or valet via text message. That second key that used to live on the hook by the door? It’s now shareable in seconds, and revocable just as fast.
The one physical key MINI still gives you isn’t going away—it’s just no longer center stage. And in fact, the latest version of the MINI key fob is arguably its best yet.
A teardown of the redesigned unit from earlier this year showed a more compact design, upgraded materials, and—finally—a rechargeable battery. It’s nice to hold. It works well. And it’s still the best fallback when your phone dies or you’re lending the car to someone less tech-savvy.
For even deeper backup, MINI now includes a credit card-style key card with every new vehicle. It won’t win any awards for user experience, but it can unlock and start the car when everything else fails. And it fits in your wallet.
The quick answer is both a lot and very little. But let’s get into the details and also throw in the standard MINI Digital Key and the MINI Key Card into the mix.
| Feature | MINI Digital Key Plus | MINI Digital Key | MINI Key Card | Traditional Key Fob |
|---|---|---|---|---|
| Technology | Ultra-Wideband (UWB) + Bluetooth | Near Field Communication (NFC) | NFC | Radio Frequency (RF) |
| Unlocking | Hands-free (automatically unlocks as you approach) | Requires holding phone to door handle | Requires holding card to door handle | Remote unlock with button press |
| Locking | Hands-free (locks when you walk away) | Requires holding phone to door handle | Requires holding card to door handle | Remote lock with button press |
| Starting the Car | Phone just needs to be inside the car | Phone must be placed in the smartphone tray | Must be placed in the smartphone tray | Push-button start when fob is inside the car |
| Personalized Welcome Scenario | Yes (lights, profile, settings load automatically) | No | No | Yes (lights, profile, settings load automatically) |
| Phone Battery Dead? | Works for up to 5 hours (iPhone Express Mode) | No function | No function | NA |
| Shareable Key? | Yes, via text (also offers usage restrictions available) | Yes, via text | No | No |
| Security | High (UWB most secure as it prevents relay attacks) | Moderate (NFC requires physical contact) | Moderate (NFC requires physical contact) | Moderate (RF signals – least secure & can be intercepted) |
| Best Use Case | Hands-free, high-security, seamless daily use | Basic digital key alternative | Backup for valet or service appointments | Traditional physical key for all functions |
Digital Key Plus is the most advanced option, offering hands-free access, personalized settings, and the highest security.
Digital Key is a step down, requiring a tap-to-unlock approach but still offering digital convenience.
Key Card is best as a backup solution for valet or service situations.
Traditional Key Fob is the most similar to the Digital Key Plus in the way it works day to day but offers less flexibility to share and is much less secure.
In short, Digital Key Plus is the next-level experience—hands-free, automatic, and packed with personalized features. It beats out the standard key fob in its flexibility to share and robust security. The standard Digital Key and Key Card is more of a tap-to-unlock solution replying on NFC.
Using Digital Key Plus isn’t hard, but it does require a little upfront setup. Here’s a simplified overview based on MINI’s official guide:
The process is smoother than previous generations, and once set up, it’s nearly invisible in daily use. If you’ve ever used Apple Pay or tap-to-unlock hotel keys, you’ll feel right at home.
Let’s be clear: not everyone will love this. If you’re the kind of person who keeps a spare house key duct-taped inside a planter, the idea of losing physical redundancy might be unsettling.
But for most people, the benefits are real. You get:
You also get a glimpse of where the industry is headed. Tesla started here. BMW refined it. Now MINI is making it standard.
MINI’s shift to a single physical key is less about cost and more about confidence—confidence that the phone in your pocket can now do the job better, faster, and more securely than a key fob ever could. It’s not without trade-offs, but it’s also not a downgrade.
In fact, once you get used to your phone unlocking and starting your MINI automatically, the old fob might start feeling like a relic—something you keep in a drawer, just in case.
Which, ironically, is exactly what the second key always was.
