Great service and application. Love it. Even when I lock my keys in the car I can open my car remotely

Decent app but flawed

Not exactly a review but a general comment.
Wouldn’t it be great if this thing would tell me if it my doors are locked or not? Seems like something that should be automatic instead of me forgetting if II led it and going through the process.
