Assuming you have to take it off because of the orientation of the antenna. What about ‘knuckle bumping’ the car so that the orientation is proper? Does that work?
Hi Chris, yes if you “knuckle bump” the ring does work. I still find it easier to remove it but that’s just my preference I guess. Maybe if this was a more primary way to unlock the car, leaving the ring on might be easier? I use it as a back up only and it’s been great to have. Thanks for the question.
Thank you very much, for the idea. I have a question, do you remembet the dimension of the mini chip? I will buy a ring (channel & ceramic must ı understand) but ı dont want to sand the chip. 4mm or 6mm or 8mm ❓ Thanx
@Human Doing, thanks for the great video! I'm seeing a lot of questions as to why you had to take the ring off in order for it to work. I experimented with this and got a working solution which allows you to keep the ring on--if anyone would like to see a video on how this is done, let me know, and I'll make one.
Yes. I'd love to see it I am toying with the idea of using 38awg wire as the inlay. A base wrap at first then the antenna and chip. Then wrap until it's proud of the ring. And then sand and polish. Whatcha think? I believe it should help the antenna
Thinking of making one for myself but don't have to take the ring off every time in order for it to unlock. @phoenixhangar you'd experimented with this and got a solution. have you made any videos and/or any hints how to do it? please share. By the way, great DIY video by @humandoing9675.
@@phillippham9998 Kudos to you for aiming to make one for yourself! With everything else going on, I have not had time to make a video...yet, haha. However, I'd be more than happy to share tips on how to get it to work while still keeping the ring on. First let me say that based on the way @humandoing9675 wound his antenna, if you imagine a shaft running through the hole in the ring, that shaft would need to be pointing into the A-pillar. Thus, the ring has to come off, unless you can bend your finger really, really, REALLY far (and your fingers are absolutely tiny...). I'll make a video demonstrating this at some point, but maybe somebody else can get to it first (in which case tag me lol). But if you wind the antenna into a circle, pinch it to form a very skinny ellipse, then bend the ellipse around one side of the ring, you'll be able to unlock the car while still keeping the ring on. In order to avoid screwing this up, I recommend working with the winding configuration to first create a circle of wire capable of unlocking the car. The key is to avoid folding the antenna back over itself, as this disrupts the antenna's electromagnetic field. A method that worked for me was to: (PRE NOTE: You *may* have to CAREFULLY) fully unwind the antenna wire--I had mixed success this way, so maybe try it without, then, if that doesn't work, unwind it) 1. Take a short, rigid tube about one inch in diameter 2. Imagining the NFC chip as the top of the wire and the opposing curve as the bottom, pinch the halfway point on the wire against the tube 3. At this, you should treat the wire on the left-hand side of the tube as one part (not "side", but "part", as both sides should form circles at the end) of the circle, and the wire on the right-hand side of the tube as the other part of the circle. 4. Using one infinity/figure-eight twist per circle, twist the wire and push the circle that forms on to the corresponding side of the tube. 5. In the end, the original piece of antenna wire you were pushing against the tube should act as the midpoint for the set of newly-formed circles wrapped around the tube on either side of the mid-line. Now, you should have a circular antenna about one inch in diameter capable of unlocking the car. At this point, you'll want to pinch the side of the circle to form a very skinny ellipse, then bend the ellipse around the inlay of the ring. The result should be a loop/ellipse taking up about half of the ring's inlay. This configuration maintains the circular pattern needed by the antenna wire while also shifting the polarization to work with the human finger. Hope that helps somebody, and cheers!

Very cool idea. Any idea why you have to take the ring off for it to work? And just in case you were wondering, there ARE rfid rings you can buy with a RFID Reader Writer Copier for fair decent prices. I, like you, would likely take the DIY route as well.
As far as I’m aware. You need a longer antenna to allow the ring to work while wearing it from a distance. knuckle bumping the b pillar works while wearing it but I prefer to take it off. Not a big enough of a deal breaker for me to worry about it. It’s a back up key and not used often, but it comes in handy. Regarding other RFID rings, from what I’ve read, they don’t work with Tesla’s.
It probably depends on the frequency used, and encryption. Tesla is probably more secure than the joke "security" that exists for building access? But also, all the 125kHz* rings online are either black, or silly fake wood with the grain going perpendicular to the ring "flow." I see only like two companies in China making them on AliExpress/eBay/Amazon. All the same design, not that great. 😞 But this video is amazing for DIY ideas. * (mine is not for a Tesla)
I can try to do that in the future. I tried to show the ring blank in the video. You can use just about any type of CA glue, just make sure it isn’t the really fast drying type.

The antenna needs to be a little longer to work while it’s still on your finger. I’ve considered making one with a longer antenna but it isn’t an issue for me. This is a back up key and removal isn’t an issue. It’s really come in handy.

@@lowspeed2000 it possible? The reason I picked CA glue was because of how thin it is. It goes deep into the veneer and is easy to repair. It also dries clear.

You could easily make this into a necklace instead of a ring if you wanted, but you would need to get really close to the car to open the door and start the car. This is my back up key, my phone is what I use 99% of the time. Honestly, it’s been really convenient having the ring.
@Nanette Jackson great question, the ring needs to be taken off due to how the antenna wire was wound. Let me know if you'd be interested in a video explaining this and how I solved it, and I'll see if I can put one up.
@@dscarty I don’t mind though. The key cards are easy enough to get and while they aren’t cheap, they are still reasonably priced in my mind. And, the ring has been flawless so far.
I do take the ring off when I use it but because it’s a back up key it won’t be used often. Better than the key card for me at least. I don’t have a wallet or keys of any kind.
I just tried this and the chip was fully 4.7 mm wide and I was unable to take enough off the edges to fit in the 3.98 mm ring core. The wire lands came off the chip.
The wire leads are easy to break. I had one other person contact me about this. They were able to solder the wire back on and the ring works. I didn’t measure the chip, but I only needed to remove a small amount to get it to fit the 4mm space in my ring.
@@humandoing9675 0.7 mm is a lot to take off. 14%. My key card is a new one so I don't know if they are sourcing different chips. if it was just the broken wire i could have reattached it but the lands came off both ends before I even got close to it fitting. Cool project but I couldn't make mine work. if I could find a 5mm ring blank it would work fine.
I'll add a bit to this--the ring itself uses an NFC chip (NFC being a subset of RFID). As far as I can tell, Tesla's pretty stingy when it comes to adding keys, so your DIY ring will need to be built from an actual Tesla key (third-party NFC/RFID rings have been reported as incompatible according to my research). That being said, Robert Quattlebaum has done some fantastic work with designing a JavaCard/Applet Tesla key if you wanted to use something like that (ruclips.net/video/QBP_Hjlpwjs/видео.html). He also has a GitHub page detailing his work, so if you're trying to avoid Tesla keys, maybe check that out. Hope that helps, and cheers!
I wear it every day. I did apply more CA glue finish to touch up some spots on the finish that were chipping, but nothing really bad. Still works the same as the day it was made.
All model 3’s and Y’s use the same key card and Bluetooth connections. No fob needed, but you can buy one. The car unlocks as you approach with your phone. You don’t have to do anything but get in the car. The key card (or ring in my case) needs close contact to work. Like when you tap your bank card. It’s the easiest entry system of any car I’ve owned.
@@jas8238 this cost me $30 Canadian and I can make it look anyway I like. If you’re willing to take the 15 minutes to make one, go for it. If not, buying one works too. Good idea either way.
I included details on the ring blank that I used. 4mm channel. No issues with mine. I’ve made several now, all good. A larger channel will allow you to skip a step, but either should work.
apparently you don't have to take these rings the whole way off to unlock/lock your tesla. Instead you can just bend the finger its on and place that by the front window
This probably isn't much help if you already glued the wire in place (unless you put the ring in acetone again haha), but I might be able to help you with this. First, does taking off the ring and placing it flat against the B-pillar work? If not, how did you wind the antenna wire?
No, once the car reads the ring on the centre console once, you are good to go. Comes in handy for me when I want to swim. I can leave my phone in the car (off) and not have to worry about anything.

Hey please i want to know: does the ring need to be an NFC or RFID ?? Or both ?!
I’m not sure what you are asking? The Tesla key card is RFID, but the ring blank itself is just ceramic.
I'll add a bit to this--the ring itself uses an NFC chip (NFC being a subset of RFID). As far as I can tell, Tesla's pretty stingy when it comes to adding keys, so your DIY ring will need to be built from an actual Tesla key (third-party NFC/RFID rings have been reported as incompatible according to my research). That being said, Robert Quattlebaum has done some fantastic work with designing a JavaCard/Applet Tesla key if you wanted to use something like that (ruclips.net/video/QBP_Hjlpwjs/видео.html). He also has a GitHub page detailing his work, so if you're trying to avoid Tesla keys, maybe check that out.
Hope that helps, and cheers!
the material you chose were Tungsten and ceramic, do you think the steel also could work? not interference to chip and wire?
I suppose it could if you isolate the antenna wire?
How is the ring holding up after 1 year of having it? Have you experienced any problems?
I wear it every day. I did apply more CA glue finish to touch up some spots on the finish that were chipping, but nothing really bad. Still works the same as the day it was made.
@@humandoing9675 Awesosm thanks!
Darn. I only have stainless and titainium blanks. Unfortunately I have to make my own because I wear a 14.5 ring. let me see what i can order. lol
You could make the entire ring from wood.
I was gonna recommend a ceramic blank, but the largest size they have is 14--sorry man, hope you found something! : )
Wait, so these newer models don’t have keyless entry?
All model 3’s and Y’s use the same key card and Bluetooth connections. No fob needed, but you can buy one. The car unlocks as you approach with your phone. You don’t have to do anything but get in the car. The key card (or ring in my case) needs close contact to work. Like when you tap your bank card. It’s the easiest entry system of any car I’ve owned.
Can you make a silicone ring? I'll definitely pay you! 😆
@@courtneyduncan-byer360 I haven’t tried that. I’d be worried about the antenna breaking.
Right now, an actual smart ring or bracelet is less than $100 bucks. No need to MacGyver it. Still a cool video.
@@jas8238 this cost me $30 Canadian and I can make it look anyway I like. If you’re willing to take the 15 minutes to make one, go for it. If not, buying one works too. Good idea either way.
This does NOT work with a 4mm channel ring, once you shave off a "few THOW" it renders the chip to not work. I had to use an 7mm inlay ring for mine.
I included details on the ring blank that I used. 4mm channel. No issues with mine. I’ve made several now, all good. A larger channel will allow you to skip a step, but either should work.
apparently you don't have to take these rings the whole way off to unlock/lock your tesla. Instead you can just bend the finger its on and place that by the front window
This works for me as you said. I don’t use the ring often, but it has come in handy.
Sort of--it does depend on 1) how you wound the antenna wire, 2) how long your finger is, and 3) what type of ring you have (DIY vs Tesla-produced).
How long did the acetone take to disintegrate the card?
I gave it about an hour. It may take less time though.
@@humandoing9675 ok thanks
Awesome job but I think I would just pay the $60 to buy one🤷🏻♂️. Thats a lot of work.
I can make the pretty quickly and it’s fun. To each their own.
Please sell these!
I would make them for anyone interested. You would need to buy the ring blank however just to make sure they fit.
@@humandoing9675 could I buy one from you ? really...
@@itswei88 sure . Send me an email and we can work out the details. Fozzdidit@gmail.com
I’m so disappointed. My ring doesn’t work and I feel like I ruined a perfectly good Tesla card. I’m thrilled about how my ring turned out though.
I went through two cards before I got one to work. The chips are delicate but I’m sure you can get it done. Just make sure to test as you go.
@@humandoing9675 at $38.00 for 2 cards, I hope I can sell a couple and recoup some lost money.
This probably isn't much help if you already glued the wire in place (unless you put the ring in acetone again haha), but I might be able to help you with this. First, does taking off the ring and placing it flat against the B-pillar work? If not, how did you wind the antenna wire?
Do you make other rings that can't be shown here? JK, great job. Very cool idea.
Not yet, but I have thought about making some for other Tesla owners.
Don't you need to take it off to drive the car too, and keep it on the center console? Not very advantageous over the card.
No, once the car reads the ring on the centre console once, you are good to go. Comes in handy for me when I want to swim. I can leave my phone in the car (off) and not have to worry about anything.
Damn I paid $120 for the ring on amazon
All good. They come in handy. You can always make a spare!
All that effort to then have to take the ring off 😂😂😂 bro use the phone!
You don’t have to take it off, but I find it easier. Up to the user. Keep in mind, it’s my back up key.
bummer you have to take the ring off to use it.
@@TimGray you don’t have to take it off. But I do prefer to.
Tesla is that cheap for not including the ring.
I don’t think they thought of making a ring. Maybe it will be an option in the future?
So Amazon Is selling this ring for the tesla so I really hope u got this idea copyrighted!!
I wasn’t the first. But doing it yourself saves money and you can customize it to your liking.
Too bad it needs to be taken off to use it.
You don’t need to take it off. However I do find it easier to use when I remove it. As a back up key, I think it’s an excellent solution.
Dumb
To each their own. I’ve enjoyed having it.
Why would you.... It's actually not dumb, and even if it was... why be that mean person?
