Horn honks 3 times on door close

Recommended Posts

I have a 2018 Sierra 2500HD that has recently started honking the horn 3 times every time I shut a door. It happens with every door, whether the truck is running or not. Any ideas as to what's causing this? I leave for work fairly early in the morning and I'm sure my neighbors don't appreciate it.

Any chance your extra key fob is in the truck?

Nope. I have 2, one is on my wife's keys up to 20 miles away, the other is in my hand.
