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.

    Easy to install. Not sure why it’s not programmable on the truck settings. Big Brother protecting us from ourselves?

    Fixes one of the most annoying features

    Posted by Nate on Jul 26th 2019

    Straightforward fix for the worlds most annoying feature. I like the fact that you can turn it on and off so simply. A little expensive for what it is, but again fixes a feature that I couldn’t stand without needing to do or learn any programming.

    Posted by Chris on Jul 1st 2019

    Super easy to install, plug it in, wait for green flash and then no more annoying horn honking when I get out with my key in my pocket. Now I can keep my key in my pocket all day.

    Very fast shipping for this product. I plugged this into my truck and it was a done deal in under 10 seconds. Extremely fast. Now I dont have to hear my horn honk when every door closed on my truck when I pull into a store.
