Users need to pair their iPhone or smartwatch with the car's key function; Hold the Apple device near the car's NFC reader; It involves an authentication step with Face ID or Touch ID to unlock the car; You can also use the quick mode in the app to skip the authentication process and unlock the car; The digital car key can also be shared via messages, allowing friends or family to unlock the vehicle.
When I first got my car, I also found the digital key quite novel, but it’s actually super easy to use. First, you need to download the brand-exclusive app on your phone, log in to your account, and then place your phone near the door’s sensor area to pair it. Once successfully linked, the car will automatically unlock as you approach, and you can start it by stepping on the brake. For daily errands like grocery shopping or walking the dog, you don’t need to carry the physical key—just bring your phone. One time, a friend needed to borrow my car temporarily, and I simply shared access via the app, setting a specific time window for convenience. Just remember to keep your phone charged and Bluetooth enabled. If your phone runs out of battery, you can still use the backup NFC card as an emergency option. After using it for over half a year, my bag feels lighter without the extra keychain, and paying at gas stations with my phone is much smoother without fumbling for car keys.
Digital key, in simple terms, turns your smartphone into a car key. The experience boils down to three key operations. First, complete Bluetooth pairing between your phone and the vehicle by selecting 'Add New Key' in the car's system, then hold your phone with the app open near the center console for 30 seconds to finish authentication. The most seamless daily feature is touchless unlocking – the car door automatically opens when you approach within 1 meter with your phone in your pocket. To start the engine, just press the brake and ignition button, and the system will automatically recognize your phone's authorization. A handy tip: if your wet phone struggles with recognition during rain or snow, tapping 'Start Engine' in the app still lets you drive away. When sharing access with family, you can precisely control permissions – like granting only passenger door access or setting time restrictions – offering higher security than physical keys.
Last week while camping in the rain, using my phone as a car key was way more comfortable than fumbling with wet metal keys. Digital key pairing is simple: open the car brand's APP, find 'Add Key' in vehicle management, place your phone on the wireless charging pad and wait for the vibration prompt. Daily use is convenient - approach within 2 meters and the lights flash three times to unlock, which is three seconds faster than traditional keys. Note that compatibility varies by brand: my Tesla unlocks with the phone in my pocket, while my BMW requires placing the phone against the center console. For lending your car temporarily, just select a contact in the APP to send a virtual key - much safer than mailing physical keys. Remember to unbind from old devices when upgrading phones to avoid false 'key lost' alerts.
