Ok so don't kill the messenger...

The federal regulation for hoods is § 571.113. it classifies a hood as a piece of the vehicles body which covers a storage area as well as engine. So from that we can gather that it doesn't have anything to do with an antiquated engine rule.

The issue, from my perspective, is the double latch mechanism. The vehicle code mandates a double latch to prevent the hood from flying up in motion. If you pop the hood with FP or the 7-8 button you hear the release twice, hence the double latch.

This of course bypasses the double latch requirement, therefore I'm sure there's associated risk. Obviously, as others state, the car knows when it's in motion vs parked. I'm thinking it has something to do with a potential for malfunction or accidental release while in motion.

I could also see domestic abuse or other assault incidents where someone could prevent you from driving by popping the hood via 7-8 without the code. I could probably come up with a handful of other possible reasons but it would all be speculative, so I'll refrain. Point was made.

I'm actually shocked that they were able to get around the double latch when parked. So I'll count our blessings for now.

And get this ... When I turn the power on, meaning I get in the car, press the brake and push the round power on button, I can open the door, get out, put in my code and press 7-8 and the frunk will open while the vehicle is on... I'm curious if I can do this in drive! I'll need to have someone test that with me since I can't be in drive and outside the car at the same time.

Ok, so 7-8 opens the Frunk once the code has been entered. I’m waiting for my Mach E to be built, but I’m curious and was hoping someone can try this to confirm. 3-4 unlocks all doors and 5-6 opens the liftgate. If so, that is some seriously old school Ford tech that is still relevant (useful?) today. I can remember that trick from back in the 80’s on a Lincoln Towncar my grandparents owned. Naturally 7-8 didn’t do anything back then, but the fact that Ford added it on the Mach E as that button sort of leads me to believe that they have carried forward something that they started 30+ years ago.

I will try for you tomorrow morning.

Certainly not with that attitude!
Although I know you were joking ... this inspired me to actually think. I can just roll down the window and climb out it a bit. I got this!

But was I?

It can prevent the shift, but does it? I haven't tested that. I can tell you it cancels a remote start if you pop the frunk.
But as I found out it doesn't turn off an already turned on car when done via the keypad. I'll try shifting into drive with it open tomorrow and also try the 7-8 while in drive already.

Too late, my "accident attorneys" were provided with screenshots.

Sorry to take us a little off topic, but if there are codes to unlock and open things, what about rolling all the windows up after you exit the car? My cheap VW Jetta can roll up all the windows and sunroof when the key is inserted in the door and cranked and held to the right. I think you can open everything back up by cranking they key in the door to the left as well.

Very interested to see what @DevSecOps reports about the codes to unlock and open the hatch.

You can do this in the FP app. You might be able to by holding lock (for up) and unlock (for down) on the key fob as well. That's how it is with Audi. We have an atmospheric river over us right now so probably not the best time for me to try that one, but I'll get back to you on it.

3-4 unlocks all doors and 5-6 opens the liftgate.
I can confirm that neither of these key presses do anything for the MME - on my version of firmware.

@mkhuffman I was unable to get the windows to go up and down using the key fob, button hold. So it appears the only way to do this is via the FP app.

Ok so here's my last follow up based on what people have asked me to try.
  1. Via the keypad the frunk cannot be opened while in drive by executing the code + 7-8
  2. The frunk can be opened via the keypad while the car is "on", just has to be in park
  3. The car CAN be driven with the frunk open. It warns to this on the display, but you can drive it.
  4. The frunk pull release in the car can only be operated with the drivers door open, regardless of drive mode.
I think we've exhausted a bunch of things with this thread and the main conclusion is that with the newer firmware you can open the frunk with the keypad using your code and 7-8 unless the car is in drive. It will not work without your code and no other key combinations are active to do things such as window or liftgate operations.

Thank you for indulging us and going through all the permutations!

The owner manual says
“You can use the keypad to:
  • Lock or unlock the doors and liftgate.
  • Program and erase user codes.
  • Arm and disarm the anti-theft alarm.”
Obviously it is incorrect for the current GT firmware Since it is confirmed that the keypad does not operate the liftgate.

It doesn't say operate. It says unlock.
