Howdy folks,

When I bought my 06, the dealer offered an alarm system installed for a reasonalble price. The one thing I don't like about it is the horn sounds whenever you lock or unlock the doors. Anyone know how to turn off the horn for the lock/unlock function? Can you turn off the horn for the lock/unlock, or does it use the same feed for lock/unlock and sounding the alarm if somenone tries to get in? Another question about the alarm, I now have a small mico-switch installed next to the underdash hookup for the OBDII port. Any ideas what this is? Any ideas on who makes the alarm the dealer installed?

Thanks for the help

 

I'd say the "microswitch" could/would be your Valet switch. To disarm(turn-off ) the honking if you set it off getting inside the truck.

 

I'd say the brand is up to the dealer, but in my experience it’s usually Avital.
