Close any door and get three chirps

[Jackson out west]

After 15 months of ownership my 2019 GMC Denali 3500 started giving 3 chirps every time any of the four doors was closed.  In Setting/Vehicle there is nothing in the menu to catch this.  The Gm tech who called didn’t have an idea at this point.  I should add that the keys are outside the truck with me.  And, it chirps when I close the door when I’m inside with the key in the ignition and the truck running.

Mine does it if I leave the remote in the truck.

This alert can be modified in Settings I believe. I have keyless start and mine is set to do this if I exit the truck with the engine off and the keys left inside.

definitely remote in truck ... you dont have your second remote in there as well do you

Like mentioned above, mine will do this if I leave the remote in the vehicle.  Check to make sure your second remote isn't in the vehicle as well by leaving your primary set in the house while trying to enter and start your truck.  If your able to enter and start your truck while your main set of keys is in the house, then you need to start searching the truck for your second set.

No keys in the truck at all.  But, catch this, the problem stopped the next day!  Just posting on this site produces miracles, I guess.  Or, there is something in the alarm system (not he software) that I hit when poking around in and under the dashboard.  GM in the meantime didn’t have a clue.  Anyone out there figure it out?

It will do it with the engine running, key in pocket and you exit the vehicle.  The fix is in settings.

Just thinking out loud here.... batteries in remote going low?

its a warning the remote is in truck with two beeps, but could beep different with the second remote inside too.

Mines did the same thing, beeps 3 times even with the keys outside. I found a temporary solution. I disconnect the battery then reconnected. It'll come back like every 3-4 months tho
