Need help on horn honk

Does anyone have a truck that honks the horn when u lock and unlock the truck? Also, if u have an alarm, are u still using the oem key fob? I am wanting to add the horn honk to my truck

 

These trucks do no honk or beep or anything when you lock them.

The only time they do (from what I understand), is if you have a factory alarm.

If you don't have the factory alarm and want a beep, there is a writeup to ADD a beep.

If you use the search feature (upper right in the blue bar) and type in:

Honk on lock
or
beep on lock

You'll find all sorts of information.
