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.

    4d tech takes over where some lazy designer at Ford got tired and quit on a Friday afternoon. This is the best hundred bucks I have spent on my truck.
    At the risk of losing my man card, it took longer to read the instructions than to use the product.
    Stop reading and buy it, you won't be disappointed.

    Thank you.

    I just installed this on my vehicle. It worked perfectly.

    4d Tech makes a decent vehicle excellent. They takeover where a half botched design(er) quit. The honk eliminator makes the pickup what it should have been in the first place. This is the best $100 I ever spent on this truck.

    Not only did the product do what it stated it would do, it was simple to use. It worked exactly as advertised.

    It is rare to find something that works as well as these 4D Tech products. This is a demonstration of yankee ingenuity.

    Finally rid of that annoying feature.

    First of all, I love my Ford Superduty. But the double honk safety feature was driving me crazy. I would forget about it and get out of the truck to do something while the motor is running and HONK HONK!!!,. Usually this would happen at 6 AM while hitching the trailer at a quite campground or in my driveway before leaving for work. I understand why Ford incorporated the feature but there is no way that I won’t notice that my Diesel engine is running, and I don’t park in a garage. First I thought about getting Forscan and a OBCD II reader but decided that is too much technical stuff for me. Then I found the 4D Tech product and ordered it. Install could not be easier, just plug it in and watch the lights as the instructions state. Finally I am free of the double honk! No more jumping in the air when the horn surprises me, no more guilt and questioning looks for disturbing others. “Hey man, why are you honking your horn?” If you have this problem, get this device right away and get instant relief.
