Mine works as designed, although I have a 2019 year model, so never has been an issue. I have it set up for 1 press lock all doors no horn honk, and 2 press horn honk. I will typically use the 1 press method but have seen the usefulness in the horn honk 2 press in a few scenarios.
1. When I'm home and in and out of the truck a few times during the day and at the end of the day I do not remember or just want to be sure the truck is locked for the night and am inside the house and just grab the fob and double click and listen for the horn honk to assure me the truck is secure.
2. When at an event like an LSU (Geaux Tigers!) football game, Saints (Who Dat!) football game, or Mardi Gras
(Laissez les bons temps rouler) and you park for a tailgate at let's say 10:00 A.M. and leave the game/party at say 11:00 P.M. with a FEW adult beverages in between and from the time you parked to the time you are about to leave, 100,000 other people have parked as well and you know the vicinity of the where-about that you parked but not exactly, when you get close, double press and follow the horn honk to your truck.
