Mine is also "hard to push down".. but I go in the frunk probably once a week, and I close it pretty much how Cyclone described, and I've never had a problem. Just place pressure spread out over your entire palms and it just clicks down. If I ever felt the metal bending beneath my palms, I'd stop (that has never happened though).
I also think this is way overblown! If you're gentle and careful with it, I don't think anyone would have this problem. Just don't close it like a regular trunk, or drop it from 2-3 feet, and it will be fine. I don't think it's "high risk of damage"... it's a "slight to moderate risk of damage if you aren't careful."
To be clear, because yours is "hard to push down" I should disregard that mine is substantially harder to close than other vehicles its age, to the extent that the tech who took a look agreed? It wasn't only my opinion. There's just nothing they could do about it because there's no means to adjust the mechanism.
I will admit it's a little frustrating to see "If you're gentle and careful with it, I don't think anyone would have this problem." This is my third vehicle with an aluminum hood, and second with an aluminum frunk, and it's always been treated "gently and carefully." To someone who has babied this thing so much, that hurts, and it's especially frustrating that even asking if there's been any updates means we do it all again.
Maybe the issue is overblown, maybe it isn't, I don't know or care, but as someone who has a vehicle that seems to be at high risk (either due to design or owner) I wish it were possible to ask if there are any updates on the issue without rehashing who is to blame.
For fear of creating a dent, my wife has never used the frunk of our P85 (made Jan 2014). I'm worried about putting my hands anywhere near the crease zone so I close it with my hands all the way on the corners, like we saw all the workers doing it on our factory tour, but being shorter, she can't apply enough force with her arms spread that far.
Similar here. When I put her through "frunk training" about a year ago she couldn't get the leverage to close it using the new recommended wide arm stance. She had to put her hands closer together than mine to get the force necessary to close the frunk. Still in the green zone, but closer than I'd prefer.
One day last year when we were at the service center we walked past a dozen MS's in the parking lot and half had dents, so I sympathize with your idea of modifying your key to force people to use the screen to open the frunk. If you do it, post the details. One thing Tesla could easily add is a dashboard frunk disable option on the screen to prevent accidental frunk use.
It's been a little while now, but the TMC Connect in Monterey was similarly a horror show. I wanted to check at the TMC San Jose this year, but we were much more spread out in the convention center lot.
