What is a Digital Key for a Car?
Your smartphone goes everywhere with you, including places that perhaps it should not. Given that it’s always present, some car companies are now offering digital key technology through their smartphone apps. A digital key for a car uses your smartphone to operate a vehicle’s door locks and to start the engine, which means you don’t need to carry the key fob with you.
Several automakers offer digital key technology. For example, BMW Digital Key is compatible with the Apple iPhone. Hyundai Digital Key works with Google Android devices. And Lincoln Phone as a Key plays nice with both Apple and Android smartphones.
Digital Key for cars remains uncommon. Lincoln offers the technology on its Aviator and Corsair SUVs, while BMW makes it available on nearly every vehicle it sells. You need not buy a luxury car to get digital key technology, though. Hyundai is expanding availability of its version of digital key, most recently to the redesigned 2021 Elantra, a compact sedan aimed at a youthful, tech-savvy audience.
