Something new on the 2022's? The 3 time Honk Warning is the Warning you receive when You shut off your truck, and try to leave the keys in the vehicle. The vehicle horn Honks 3 times and the driver's door unlocks. (FYI, this warning only works 2 times, after that, you can lock yer keys in the vehicle). It is not a warning on the FOB leaving the vehicle, but when left in the vehicle. Are you possibly leaving the second "Key Fob" in the vehicle? That would be my only thought unless your BCM needs to be reflashed.
Preventing Inadvertent Locking Of Passive Entry Key Fob In Vehicle:
To minimize the possibility of unintentionally locking a
Passive Entry key fob inside your vehicle, the Passive Entry
system is equipped with an automatic door unlock feature
which will function if the ignition switch is in the OFF
position.
If one of the vehicle doors is open and the door panel
switch is used to lock the vehicle, once all open doors have
been closed the vehicle checks the inside and outside of the
vehicle for any valid Passive Entry key fobs. If one of the
vehicle’s Passive Entry key fobs is detected inside the
vehicle, and no other valid Passive Entry key fobs are
detected outside the vehicle, the Passive Entry System
automatically unlocks all vehicle doors and chirps the horn
three times (on the third attempt ALL doors will lock and
the Passive Entry key fob can be locked in the vehicle).
