Can You Drive Without the Key After OnStar Remote Start?

[Alexandra]

You cannot drive without the key after OnStar remote start. When the vehicle is remotely started via the mobile app, it needs to recognize the key to verify the owner. If the key is not detected, the vehicle will not start. Here are some additional details: 1. Some vehicles are configured such that when remotely started, the doors cannot be unlocked remotely—only the car key can unlock them. If the doors are opened in advance, the remote start function cannot be used to prevent unauthorized driving. 2. Even if the vehicle can be remotely started and the doors unlocked, driving is not possible without key detection. The dashboard will continuously display a "key not detected" message.
