Headlights flashing sitting in the garage

[Apeacock]

So I was working in the garage on my truck with my 2019 Gt sitting alongside when I noticed the headlights flash. It happened several more times over the next hour or so. My remote is no where near the car and the battery is fully charged. Anyone ever have this happen to them? Can't figure it out and it's a bone stock pp2

Are you sure someone wasn't in the house pushing the button on the key fob just to mess with you as in a prank?

No I was the only one home at the time. I don't drive it much so I'm worried about it killing the battery
