4Dtech 2021+ Bronco Double Horn Honk Eliminator 


The double honk can really get you when you have to step away from your vehicle for a minute and leave it running.  Usually it gets us right when we pass the hood.  It can be startling, annoying, and can disturb others.

This is a plug and play solution that eliminates this issue.

NOTE:  There are NO refunds or exchanges once this has been used as it marries the device to your VIN rendering it useless to any other vehicle.  The device is considered used once it has been removed from it's sealed baggy.

No More Double Honk

Worked perfectly on my 2023 Bronco Black Diamond. Easy to use just like in demonstration video. Highly recommended to get rid of that annoying double honk when exiting vehicle with key fob. Essential for winter when you want to leave it running with doors locked to do quick errands like paying for gas without double horn blasting like an idiot.

Bye Bye Double Honk

This did exactly as advertised. It took me longer to open the packaging than it did to plug in and remove the annoying double honk! Easy, fast, perfect! This was worth every penny if you hate the double honk as much as I did!
