I have an Acura MDX 2022 and I wonder if there is a way to auto-lock a car in more cases.

Typical problem is my wife and son come from shopping, my son opens the back to unload the stuff and my wife goes and enters the house. My son finishes unloading the car, closes the back but since the fob is with my wife and away, the car refuses to auto-lock.

Is there a way to tell the car to lock automatically if the fob is away and all doors/tailgate are closed? Maybe after some time of inactivity?

Thanks.

 

Other than using the smartphone app the short answer is no
