This Horn Honk programmer allows you to disable and re-enable the double horn honk if you remove the keyfob from a vehicle that is still running (vehicles with push button start).  The programmer plugs into your vehicle's OBDII diagnostic port under your steering column. In a matter of seconds, the Flash will disable the double horn honk reminder on your vehicle. Want to re-enable it? Simply plug the programmer back in! Each time you plug the programmer in, it will toggle the features state.

    That’s what I’m talking about!

    I really love that 4DTech has taken the time to work out these incredibly helpful programming issues. I wish the auto makers would give us intelligent humans, who can make decisions on their own, an opportunity to manipulate simple programming such as the horn eliminator.

    Awesome! When I would start the truck and step out to do anything-- like scrape the windows-- the double honking would drive me b crazy! The honk eliminator fixed the problem in seconds. Thank you.

    Perfect solution. Easy to use - worked first time. Not getting yelled at by people who thought I was blowing my horn at them when I got out of the truck and closed the door. Stupid idea by Ford. Easy fix by 4DTech.

    Thank you for offering a solution to the really annoying double horn honk when step out of the car when it's running. Very annoying, and flat pissed my neighbors off when I go to work at 2 AM.

    This product is awesome. I have one for my F150 & my wifes was so aggravating the loud honking when getting out at gas station or running back into house to grab something. Plug it in & done in 5 seconds.
