FAQ
Why doesn’t BetterKey include these automations?
Automations are personal and must be created on the device where they run.
Because of this, BetterKey can’t install them for you — but we guide you through setting them up in just a few steps.
How will I know the automation worked?
BetterKey will notify you when your car is locked or unlocked.
Make sure notifications are enabled in Settings › Features › Notifications to stay updated.
