Good, phone battery matters
Convenient keyless start. Just remember it relies on your phone, so keep it charged.

No more carrying keys
For a supported model this is brilliant. Walk up with the phone and drive. Setup by a pro made it painless.

Works offline, feels secure
It does not depend on the internet, which reassured me. Locking and starting over Bluetooth is smooth and fast.

Phone becomes the key
It pairs over the OBD port and my phone now unlocks and starts the car. No network needed, it works offline every time.
