1. Your truck MUST already have standard power-folding mirrors. This programmer activates the auto-fold behavior on mirrors that already power-fold. It will NOT add power-fold to trucks that don't have it.
2. Have trailer tow mirrors (the extendable ones)? You'll need our add-on Trailer Tow Mirror Harnesses (one per side, under a minute each). Choose the Programmer + Trailer Tow Harnesses option below.
Auto-Fold Mirror Programmer
Make your 2015-2020 Ford F-150 or 2017-2019 Super Duty fold its mirrors in automatically every time you lock it — a factory-style convenience feature, unlocked with a quick OBD-port programmer from 4D Tech.
✅ Confirmed Fitment
• 2015-2020 Ford F-150
• 2017-2019 Ford Super Duty (F-250 / F-350 / F-450) Vehicle must be equipped with factory power-folding mirrors.
Lock It, Watch Them Fold
Press LOCK on your key fob, the exterior keypad, or the door lock button and your mirrors fold right in — perfect for tight garages, narrow trails, car washes, and busy parking lots.
They automatically unfold once you unlock the truck, get in, and shut the driver's door — so they aren't constantly folding and unfolding while you load up.
Program It in Minutes — Then It's Done
Installation is as easy as it gets: plug the programmer into the diagnostic (OBD-II) port below the steering wheel, follow the on-screen prompts, and unplug. No cutting, no splicing, no shop visit.
Because the tool programs your truck directly, it locks to the first vehicle it's used on and is non-refundable once used — so double-check your fitment above before you start.
Got Trailer Tow Mirrors?
Trucks with trailer tow mirrors (the ones that extend in and out) also need our two Trailer Tow Mirror Harnesses — one on the driver mirror, one on the passenger mirror.
Each side installs in under a minute. If you have tow mirrors, pick the Programmer + Trailer Tow Harnesses option so you get everything in one shot.

FAQ
Do I need power-folding mirrors already? Yes. This activates auto-fold on mirrors that already power-fold. It cannot add power-fold hardware to a truck that doesn't have it.
Will this fit my truck? It's confirmed for the 2015-2020 F-150 and 2017-2019 Super Duty with factory power-fold mirrors.
Is it refundable? It carries a 30-day return if unused. Once you program a vehicle it locks to that truck and becomes non-refundable, so verify fitment first.
Will it void my warranty or cause codes? No. It maintains your factory and extended warranties, causes no codes, and disables no features. It's fully reversible.
I have trailer tow mirrors — what do I need? Choose the Programmer + Trailer Tow Harnesses option. The two harnesses install in under a minute per side.
How do the mirrors unfold? Automatically, once you unlock the truck and open then close the driver's door.
