I have a 2018 Acadia Denali. Recently, I lost my key fob and it was a nightmare because I was out of state and didn't have a spare key. It took several days to get a new key fob made and programmed by a dealer in the area. Is there any way to keep a spare key fob inside the car? I can use my phone to unlock the car and gain access to the spare fob. Problem is, if I leave a spare key fob inside the car, it disables remote start and the horn will beep every time I lock the doors with my main fob. Is there a "safe place" to store the spare fob inside the car that won't disable remote start? If I remove the battery from the fob, will that make the fob undetectable?
