Imagine walking up to your car and instead of rummaging through your pocket or bag for a key fob, you simply tap your smartphone or smartwatch, and the doors are unlocked. No more lost keys, no more obnoxious keychains. Just simple convenience, security, and modern technology literally at your fingertips. This is not a futuristic dream anymore; this is the reality of 2025. Car manufacturers are equipping their vehicles with digital key technology, so it’s not a matter of whether you will have digital car keys; it’s a matter of when.
This article will walk you through everything you need to know about digital car keys in 2025, how they work, which cars support them, and what you should consider if you are thinking of upgrading. Whether you are a tech lover or just someone who wants simpler solutions in daily life, this guide will help you explore the growing trend of digital keys.
What Is a Digital Car Key?
A digital car key is what it appears to be – a digital version of your traditional car key. Instead of using a physical key or a key fob at the door and to start the vehicle, you use a smartphone app, smart watch or other smart device to unlock and start (sometimes drive) the car. The digital car key is simply stored in your phone’s wallet app, similar to how you store credit cards or boarding passes.
Most digital car keys use Bluetooth, NFC (near field communication), or UWB (ultra-wideband) as the technology to communicate with the vehicle. Some digital keys also have a key sharing feature, so you can share access with a friend or family member even when they live in a different time zone.
Why Are Digital Keys Gaining Popularity?
In 2025, digital car keys will no longer be a luxury, they are quickly becoming the standard. Here’s why:
- Convenience: No more forgetting your keys or locking them inside the car. Your smartphone becomes your key.
- Security: Digital keys are encrypted and often require biometric verification (like a fingerprint or Face ID). This makes them harder to steal than traditional keys.
- Key Sharing: Easily send a digital key to someone else, perfect for family use or lending your car without handing over anything physical.
- Integration: Some apps let you check your car’s location, fuel level, or even set the temperature, all from your phone.
Cars That Use Digital Keys in 2025
1. BMW
Now, let’s discuss the cars that feature this technology in 2025. Most of the large manufacturers have been rolling out digital key capability; in fact, some models now include it as standard.
BMW was one of the earliest adopters of digital key technology. As of 2025, most of the new BMW models, including the 5 Series, 7 Series, i4, and iX all come with BMW Digital Key Plus. It also uses ultra-wideband technology for added security, and supports Apple Wallet and Samsung Wallet for quick access.
2. Hyundai / Genesis / Kia
Hyundai, also known for its luxury model called Genesis, has led in digital access. The Hyundai IONIQ 5, Genesis GV60, and the Kia EV6 support digital keys on both Android and Apple formats. The key can be shared, made with different authorized users, and even controlled remotely!
3. Mercedes-Benz
Mercedes has advanced the technology with the Mercedes Me Connect App, which is being supported in their high-end models, like the EQS and the S-Class. Aspects such as unlocking, locking, and starting the vehicle can now be done as easily as picking up the phone and using the App. It even provides the ability to view vital vehicle information.
4. Tesla
Tesla has used keyless tech for years. In 2025, all Tesla models, including the Model 3, Model Y, Model S, and Model X come with key card and smartphone key access by default. Their app is one of the most advanced, offering remote climate control, charging stats, and vehicle tracking.
5. Ford and Lincoln
Ford’s Phone as a key technology, found in vehicles like the Mustang Mach-E and Lincoln Aviator, allows owners to unlock and start their cars using Bluetooth. The Ford Pass app makes the experience smooth and user-friendly.
6. Audi and Volkswagen
Audi and VW continue expanding their digital key options, especially in their EVs like the Audi Q4 e-tron and VW ID.4. Digital keys can be stored in your smartphone wallet and accessed without needing cellular service.
Is It Safe to Use a Digital Car Key?
Yes, it’s safe, but like with any tech, there are best practices to follow. Most digital keys use encryption and require user authentication, such as a fingerprint or Face ID. Plus, in case your phone is lost or stolen, you can often revoke or disable the key remotely.
Still, if your phone battery dies or you lose internet connection, you might run into trouble. Many cars come with a backup key card or allow emergency access in such situations.
And of course, for emergencies or lockouts, a car locksmith in Chicago, IL can still come in handy, especially when your phone isn’t cooperating, or you accidentally disable your digital key.

Digital car keys are no longer a nice-to-have. They are quickly becoming a must-have for car buyers who want convenience, safety, and a smarter way to drive. With more automakers embracing this tech, and phones playing a bigger role in our lives, it’s no surprise that the key to your car might soon live in your pocket, virtually.
