Firstly, a digital key allows car owners to lock and unlock their vehicles using their smartphones. According to KBB, the phone is also a full-fledged key for many automakers. In short, that means it’ll lock, unlock, and start your car’s ignition. The phone becomes your key fob, which is perfect if you lose your keys all the time. Owners need to download the car manufacturer’s app to access their keys. Many are manageable through Apple, Samsung, and Google “wallet” systems on smartphones.

Why do you need a digital key on your phone? The main benefits are reducing your pocket load and in case of an emergency. Those who lose their physical key fob will often find it easier to use their phone instead of locating the key. This locking and unlocking technology is standard with some vehicles but not on many others. Usually, it requires owners to pay a monthly or yearly fee to use the service.

However, you’ll still have to be near the car as a safety precaution.

Additionally, owners don’t need to remove the phone from their bag or pocket to use the digital key. It’ll function just like a hands-free key fob for locking and unlocking. Other devices, like an Apple Watch, can also lock and unlock your vehicle. Models like the Honda Passport also allow users to remote start the SUV from their smartphone.
