In an age where digital convenience has become a staple, the need to carry a physical car key seems increasingly outdated. With smartphones now capable of storing everything from debit cards to transit passes, the question arises: why are car keys still a necessity?
The technology behind digital keys has been around for some time. Many vehicles, such as the BMW 5 Series, have allowed owners to unlock, start, and share access to their cars using smartphones since Apple introduced its Car Key feature in 2020. Brands like Audi, Kia, and Hyundai followed suit, integrating this feature into their vehicles. During the WWDC 2025 keynote, Apple announced that 13 more automotive brands, including Chevrolet, Cadillac, GMC, and Porsche, would adopt this technology by 2026.
Tesla Model 3 users have been utilizing digital key access since 2017, foregoing the fob entirely in favor of smartphone entry. Other companies such as Rivian and Polestar have joined the digital revolution, although Rivian has temporarily paused its digital key feature for further testing, with plans to reinstate it soon, according to a recent update.
Despite these advancements, some companies like Ford still see value in traditional keys. The automaker recently launched a $200 Truckle, designed to hold the F-150’s oversized fob, indicating a reluctance to fully embrace digital-only solutions.
Digital for All
Digital key functionality is not limited to luxury cars. Devices such as the MoboKey can transform nearly any modern car into a vehicle with digital key capabilities, whether it runs on gasoline or electricity. Similarly, KeyDIY offers a solution that allows almost any car to use digital keys by emulating the secure signals that traditional fobs use to prevent unauthorized access.
The Key to Meaning
While digital key technology is both mature and mostly secure, the attachment to physical keys persists. Sean Tucker from Kelley Blue Book explains, “Most people are reluctant to go without the physical backup of an actual key.” This sentiment is echoed by Stefan Gössling, a professor at Linnaeus University, who notes that car keys carry emotional and symbolic significance for many, serving as a tangible connection to their vehicle.
