Tahoe Alarm went off while I was cleaning the inside

[johnko05]

Today I was cleaning the inside of my 2025 Tahoe High Country (vacuuming, wiping down surfaces etc) and all of a sudden the alarm went off. Does anyone know of any possible reasons why this might happen? I had to go in the house to get the key fob in order to turn it off. Here is what I did:

1 - parked the Tahoe in the garage after running errands. I have it set for all doors to unlock when putting it in park. I go inside the house for a few hours

2 - I open the front passenger door and clean. No issues. Again, all doors were already unlocked from when I came home a few hours earlier. After I'm done I leave the door open

3 - I open the right rear door and do the same. No issues

4 - I open the hatch. No initial issues, but after like 5 mins or so the alarm goes off

Will the alarm activate if the doors are kept open for a long time? Thanks in advance for any help!

I haven't pin-pointed the particular sequence yet, but I've had the alarm go off when loading the car (tailgate or side door left open). It seems to me that it could go off after some time of doors being left open if maybe the unlock feature on the fob was used, and then the fob isn't in the vicinity of the truck thereafter while a door is left open... Or something like that. I don't know, either.

I, too, am interested in learning what the exact sequence of events is that can result in this. I'm sure someone will know.
