What didn't work:

thick clay, air drying
thin clay, air drying
thick sugru (mine was as thick as the first clay one so this may work if you can get it thin enough. I did not)
thick paper clay
baking soda/super glue
replacing the broken copper wire with new wire
leaving it on paper to enclose in final material
any bits of clear tape covering the wire when you seal it up

What did work:
super thin (1-2mm per layer) paper based eco friendly "clay" that dries into a foam-like material, sealed with a thin layer of Elmer's glue (probably any white glue would work?) for stability.
 
Ok, so first: super glue and baking soda = bad idea. LOL I made a huge mess that was hard to clean up and it reacted to the plastic (I tried it on a piece that had been removed before trying ti on the actual chip). I never got any actually epoxy, I couldn't find it and the hardware store guy pissed me off by asking "shouldn't I be talking to your husband about this?" Really dude? Just tell me where it is before I put a boot up your sexist @$$. Regardless, they were out, which is why I couldn't find it.
resin/epoxy/acrylic I would have to mold and allow to partially harden to work with anyway, which seems like a lot of babysitting to get the wire/ship in and then put it together at exactly the right time. I would encourage others to try it though.

I found some self-hardening paper based foam clay that is easier to roll out and also non-toxic on amazon. It is Japanese, but hey- if it works.... Ordered it and got delivery overnight.

Day 1: I placed the chip end in the acetone to dissolve a few layers of the plastic (remember I had left the hard plastic around the chip and the little antennae). tested the chip with the now thinner plastic casing & it still worked. The chip was still wet from the acetone bath and getting rinsed, so it is not the liquid causing the problem & it is not damaged from the acetone bath.. I rolled the clay out to 2 mm thick, laid out the wiring/chip, and cut around it for the shape, same as before except it was 100% as thin as I could get it. I set the back piece on and trimmed again. This time it is just barely thicker than the credit card. I sealed the edges of the clay like normal, did the decorative touches, and set it aside to dry.
The clay was so thin you could almost see through it in places, so I used the water and a small paintbrush to smooth it out and evenly cover everything to protect it, adding tiny pieces of clay as necessary to ensure full coverage.

Fingers crossed, this is as thin as it gets and will need hardened so the plastic doesn't poke through again.

Day 2: Clay is totally dry, gently test it on the car- it works!!! plastic is very obviously trying to poke through, time to rubberize it. I went back in and plain old Elmer's glue (basically duct tape for teachers). I put a few drops on the front side and spread it around so it evenly coated the clay and let it dry, then repeated with the back and edges. I now have basically a rubberized key ring that is strong enough to not rip or allow the plastic to come through. Time to test it agin

OMG SUCCESS! The key WORKS! yay for science/engineering, I will upload something later to show final product. I added a ring to it and a little laminated card (find a Mardel's- they laminate for you). I printed the card from M3OC here: https://teslaownersonline.com/threads/key-card-holder-cup-coaster-3d-print.6353/page-2#post-87688
Yay experimentation!

My only concern about the glue is that it has the potential to get reactivated/sticky if it gets damp (like being held in a valet's sweaty hand while running to/from the parking area). I wonder if clear nail polish would do the trick. But talk is cheap--I apparently suggested you make a mess and run into a sexist jerk. ;)

Looking forward to the pics.

ok so I have had a few people pm me asking if I can make one for them in various shapes. I am perfectly willing to do this for my cost- no profit, but it would require you to send me a key card programmed to your vehicle for me to put inside the key chain, or possibly a blank that you can then have programmed (I make no guarantees it will be able to be programmed after the fact though). Cost of materials is about $10-12 (include share of the paper clay, the acetone cost- it takes ~400 mL to cover the card, plus the key ring) depending on how many colors are used and the size of the object. I used about 1 tub for my wolf, the problem is you have to get all the colors so I have no grey left. I can use any of the other colors though, I figure it at ~50 cents a tub. I can probably put it in a baggie and mail it regular mail for the cost of a stamp so no worries on that.

Again, if you REALLY don't want to do it yourself I am willing to make one for you (we will need to talk about the shape to make sure my limited art skills can handle it- LOL). However, I put up my instructions posts b/c it is realistically something that you can do for yourself in very little time and expense. It also requires a LOT less trust than sending a stranger on the internet your address and a key to your shiny new Model 3. :)

Summary below:
What you need:
1. air dry clay that you know is able to be rolled VERY thin- about 1-2 mm is all the thickness it can have for each side. I used this kind: https://tinyurl.com/ya8mpgrn
2. Acetone (not nail-polish, you need the REAL stuff from the hardware store)
3. Some type of tool to shape and decorate if desired- you can do the shaping by hand or use whatever you have around the house- knife, toothpicks, paint brushes, etc)
4. a GLASS jar (the acetone will melt a plastic jar
5. small binder clip & pencil/toothpick/tweezers/etc or other contraption to hold the chip part out of the liquid
6. Creativity! (a pic of your desired shape helps for reference)

What you do:
1. fill a GLASS jar with the acetone, up the a point where it covers the card
2. put the binder clip on the chip part of the card (top right corner) and slide something through the ring ends.
3. Dip the card into the acetone and set it so the tweezers are across the top, keeping the chip part out of the acetone. *it helps to put the jar where it will not be disturbed and tilt it on edge so the acetone cover as much plastic as possible without covering the chip.
4. Let it sit for several hours until the plastic falls away easily. You may need to peel it back.
5. Rinse the acetone from the chip & antenna.
6. Check your chip/antenna to make sure it still works.
7. Roll out your medium to 2 mm thick or less. You will need a front and a back.
8. Cut out your shape (make back slightly larger the front to smooth together the edges)
9. Place your chip/antenna down on one piece of your shape. Gently press to hold it in place.
10. Make a hole somewhere for your key ring, be careful not to nick the copper. You can also just add some sort of string or twin at this point instead of making a hole and using a key ring, but I don't guarantee that this will hold up. :)
11. Place the other piece on top of the copper to sandwhitch it b/w the 2 pieces.
12. Create any texture/decorations on the outside.
13. Smooth together the edges to seal it up. Check it on your car to be sure it still works.
14. Allow to COMPLETELY air dry.
15. Place a few drops of white glue on one side and spread it around to make a thin layer covering the entire piece. This will seal it from weather and keep the plastic around the chip from poking through. Allow to dry.
16. Repeat step 15 on the other side.
17. Use scissors or a knife to separate the 2 parts of the key ring. you want the clay shape to slide easily through the gap so it doesn't tear. You may need a third hand for this step.

Done!

PLEASE consider doing this yourself- it was not my intention to make this a business, just to help others. :) Have fun!
 
Are you able to post pictures of the result? This is very intriguing and I may try it myself...although I'm in the same "limited art skills" group as you :)
 
This custom Model 3 key fob might be a good fund raiser for a high school art class.
Probably don't want acetone in the hands of middle schoolers.
But I am favorably impressed with the abstraction of your Wolf's Head. It reminds me of a Picasso exhibit where Picasso paired the leather seat from a racing bike of the 1950s and the curved handle bars, hung on the wall, to imitate a bull's skull. It worked for me.
So I'd guess a significant number of model 3 owners would pay good money for some unique art that unlocks the car. Say $30 and the purchaser provides the card and an inspiration for unique art?
 
yep here ya go :) it works great, I had to drop my car off last night for them to check out a squeal when I go in reverse and they all had a fit over it and loved it. :)
With the instructions saying "place CARD here..." I think people would think the info card is the key, the charm is just a charm.

I will let the valet's know it is the charm, not the card, when I hand the keys over. The tesla guys figured it out pretty quick (it doesnt really make sense that it is the piece of paper), but others may not. I still plan to give a quick "do this dont do this" to the valet anyway b/c of the odd way to get out of the car, the card on it is really just there a a quick reminder if they forget how to do it.. :) I have found that most of my friends have figured out the button pretty fast though.
 
still not totally clear on the reasoning (besides just for the process of making something unique) what gain this provides. You still have a card (of similar size of the original key card) attached. Why not punch a hole in the top left corner and attach a ring (or ring plus charm)?

because I dont want it to say Tesla. I think it makes it an easy target for people to grab the key and go steal the car. They are easy to spot, so if it is easy to quickly recognize and grab the key as well, it makes it an easy target. They can spot the key from far away, walk by and lift it, casually stroll to the car and go. With others they have to know the spot number then the layout of the valet lot to find it. Still not hard, but takes a little more time/effort and they have no guarantee they wont get a 1981 volvo. lol I also like that it is unique, but mainly for the security of it.

also I don't always carry a wallet or purse so this is just easier for me on those days as well- less likely to slip out of a pocket & more noticeable if it does..

OMG I am not saying it will happen, just that it crossed my mind as a possibility.

I got it to work so I put it out there in case others liked the idea of personalizing it for WHATEVER reason so they could do it themselves.

No one is telling you that you have to do it. Don't do it if you don't want to (and as a mod you probably shouldn't troll threads).

I think I might buy one of these watches, take out the face, and try to mold the rfid and antenna into where the watch face was.

I might even have a face type piece 3d printed with soft tpu so it looks nice.

My plan is to wear this on my right arm so I can easy unlock on the pillar and console if my phone dies.
I love this idea, but I have to wonder if being recessed even that fraction of an inch will make the card not register since it's further away. I'm very curious if this works, and what types of faces could be placed in front of it (whether a watch face or just a blank) where it'd still work.
 
So, do they sell these cards individually, or is it automatically 2 at a time? I've seen a lot of references in this thread to "set of 2". I'm fine if its two (only an extra $5), but I'm curious. I'd told the local parts department that I was interested in a third card when I took delivery soon, but they didn't mention anything about coming in pairs. As such, I assume they're prepping only one, but I'm just a little curious if I'll actually get two. If I did, all the better, I can experiment a little more than I had planned :)

My initial plan is to try this inside my phone case. Was going to try it unmodified at first, but already sourced some thin silicone rubber material to sandwich it in, in case the card was too thick to fit between my slim case and phone (without damaging the phone).

They come in pairs- I asked for an extra key and they said I had to get a pair, which was fine. It is $10 for the pair (they gave me mine for free "due to the wait on the detailing team."

My 3 will unlock just fine by tapping my wallet against the sensor (the card is in the outermost pocket of the wallet). I also just tested this a bit further by putting the card inside a large book. It's able to unlock with about 0.75 inch of book between it and the sensor.

Good to know. Considering I'll have the two extras, maybe I'll do one integrated into my phone case and the other in a watch, like Tim suggested. Or maybe challenge myself to come up with some other neat implementation.

I took delivery today (which went well), but only got the 3rd key. I actually do wish they'd required it to be a pair, because I was also charged $25 to program it. Since I was paying that charge anyway, in hindsight I'd have just done two for $35 instead of one for $30.
 
it must just depend on your SC then. I didnt get charged anything to program them and they would only give them in pairs. That sucks you had to pay the fee.
I was afraid you'd confirm they didn't make you pay the fee. At the end of the day, $25 isn't the end of the world, but it's also annoying that they're not consistent about it. For that labor cost, I could've bought a few more.

Has anyone else here been charged a labor fee? If it turns out my local store screwed up here and it's not actual policy (either corporate or local), I may ask them for a refund or credit of that money.
