Tesla Model 3 owner implants RFID key card chip into her arm as ultimate hack to unlock door
Tesla owner, maker, and software engineer Amie DD has undertaken the ultimate hack: Implanting the chip from inside her Model 3 valet key card into her arm.
The idea for the Tesla bio implant, as described by Amie, came from an RFID chip she already has inside her hand that connects to her personal website and front door lock. “It’s just basic access control. If I were to tap my hand to your phone, it would automatically open a browser and go to my web page,” she explained in her video on the project. After pre-ordering her Model 3 and learning there was a key card with an RFID chip, she was inspired to connect her current chip to the new car.
Since Tesla’s chips are pretty secure, Amie had to adjust her original plan to copy its software onto her existing RFID chip and install the Tesla chip into her arm as a second bio implant. “I can get a lot of information about the Java Applet that it runs on, but I can’t take that information and write it to my current chip. So, it’s pretty secure. Good job, Tesla,” she explained. Of course, there were some challenges along the way, mostly with people doubting her ability to accomplish her goal.

“They [said] oh, you can’t like, start your car with that. It’s not secure, it won’t work. And it makes me want to do it more…because…it makes me question why. Like, why can’t you do it that way? What are the limitations?” she recounted. “And it actually makes me research it to be able to reverse engineer it, understand how it works, why it works that way…and then at the end, it’s like going to the candy store… I did it, it’s like the Sword of Destiny.”
To obtain the chip from the valet key, Amie dissolved the card’s plastic in acetone. She then had it encapsulated it in a biopolymer to make it safe for her body, calling in the expertise of Amal Graafstra of DangerousThings.com, a company specializing in “biohacking” and RFID chip implants. Finally, Amie’s chip was implanted by a studio experienced in body modification called Shaman Modifications. “I talked to a few doctors, and they were a little leery about doing this because it’s kind of a…questionable thing,” she noted.
Amie’s background goes well beyond turning her Tesla Model 3 valet key into a bio implant. She’s a self-described maker, builder, and “Magical Unicorn Software Engineer” whose projects include 3D printing, electronics, and cosplay costuming and accessory design. She regularly publishes video tutorials on those same topics and runs an Etsy store where she sells goodies like 3D printed cosplay items and unique LEGO gifts. Professionally, Amie has a background in Game Programming and Simulation and started her career at Marvel Studios, working on Captain America and X-Men Destiny. She later transitioned to Research and Development for development work on the Xbox and Playstation, as detailed on her website.
The full details and project diary for Amie’s Tesla Model 3 implant hack are additionally published on Hackaday, for anyone interested in either following along with her software/bioengineering or perhaps…interested in their own Tesla implant?

Tesla owner fixes common feature complaint with crafty DIY retrofit
Tesla owners have long griped about the wireless phone charger in the Model Y and other vehicles. It often turns smartphones into miniature ovens rather than reliably topping them up.
Software engineer and Model Y owner Michał Gapiński tackled this issue head-on with a clever DIY upgrade, swapping the cooled wireless charger pad from the China-made Model YL in for the one that came standard in his vehicle.
There are several key differences between the U.S.-built Model Y’s wireless charging pad and the one that Tesla has been installing in the Model YL. The one installed in U.S.-built vehicles lacks active cooling and relies on basic heat dissipation, leading to rapid temperature buildup during charging. In contrast, the Model YL integrates a small fan for active cooling.
Will it fit? Fingers crossed, I want a first YL charger deployed in the regular juniper pic.twitter.com/wWDqSNFVkW

This design maintains lower temperatures even in warm ambient conditions, though it does not support faster Qi2 charging on iPhones. The connector matches exactly, making physical swaps feasible on compatible consoles, but coding is required to enable full functionality.
Owners in the U.S. have complained about the wireless charging pad, with many reporting that overheating is fairly common. Within 20 or 30 minutes of placing a phone on the wireless charging pad, many have reported overheating messages on their phones, which halt charging and essentially turn the pad into a fancy place to rest your phone.
Many owners have opted to simply plug their phones into a charging cord. Tesla has acknowledged the problem by releasing several solutions for owners, including a relatively new feature that allows you to simply turn off the charging and simply act as a holder for your phone while driving.
Gapiński said that he sourced the cooled pad affordably from China, and it cost under $200 for the part.
He removed the existing console charger, swapped in the new unit, confirming a perfect connector fit, and handled the trim differences. Since the parameter isn’t fully secured, he enabled it through custom coding outside official Toolbox.
Connector is identical, she fits, now time to code it. https://t.co/Y9idgDrpCq pic.twitter.com/uwwgq6blg7

The fan activates quietly, blending with AC and seat cooling. He reported the installation was effective and the wireless charging pad worked perfectly; it even kept the phone cool as it stayed at just 86 degrees Fahrenheit. Many times, the wireless charging pad will bring the phone’s temperature well above 100 degrees, sometimes even being relatively hot to the touch.
The retrofit worked, no issues. First Model Y with a cooled wireless charger! No QI2/faster charging on the iPhone but it does not boil the phone even when it is 30 degrees outside.
The fan kicks in, it is not audible especially with the air conditioning and seat cooling. The… https://t.co/JOyR8Tb1Yo pic.twitter.com/kJcYhQIlYq

This retrofit highlighted an elegant, owner-driven solution to a factory shortcoming. It is expected that Tesla will begin installing the cooled charging pads into new cars in the U.S. soon, and hopefully, it will offer some sort of retrofit service or kit to owners here who want to use the charging pad effectively.
For those who love to tinker, it’s an accessible upgrade, proving that innovation thrives beyond the production line.

Tesla Model 3 pickup “Truckla” gets updates and a perfectly wholesome robot charger
Back in 2019, YouTuber Simone Giertz, the self-proclaimed “Queen of Sh*tty Robots,” created a one-off Tesla Model 3 build that took the automotive world by storm. Fondly dubbed as “Truckla,” Giertz noted that the vehicle was actually her dream car — as crazy as that may sound.
Now almost four years later, the YouTuber posted an update on Truckla. And just like every other big project that one probably started, Giertz stated that she actually stopped working on Truckla when the vehicle was about 80% complete. The car is driving though, but a lot of stuff was not really working very well.
Thus, for her Truckla update, Giertz shared how most of her Model 3 pickup truck conversion was essentially completed. Truckla got a lot of detailing done, she got a slight lift, and she now has a functional tailgate. One has to admit, Truckla’s tailgate is pretty darn cool.
The “Queen of Sh*tty Robots” also opted to give Truckla a friend in the form of an automatic robot charger. Unlike Tesla’s rather interesting snake charger from years past, Truckla’s charger would come in the form of a rover, thanks to her friends at robotics platform Viam. Giertz aptly named Truckla’s robot charger friend “Chargela,” which is an appropriate name for such an invention.
Also true to form for Giertz, Chargela’s first encounter with Truckla was just a tiny bit awkward. One could say that Chargela may have just been a little bit nervous on his first try without human hands helping him. Most importantly, the system did work, so Giertz would likely keep using Chargela for her Model 3 pickup.
Teslas are very tech-heavy vehicles, so projects like Giertz’s Truckla are always remarkable. The fact that the Model 3 works perfectly fine despite having a good chunk of it cut off and turned into a pickup truck bed is mighty impressive any way one looks at it. Overall, Truckla will always be one of the coolest Tesla DIY projects to date, so any updates about the vehicle are always appreciated.
Truckla’s nearly four-year update can be viewed below.

Tesla fan creating ‘CyberRoadster’ using Model 3 Performance parts in epic DIY build
A Tesla owner is taking his hobby and love for electric vehicles to new levels by creating what could only be described as one of the coolest EV-related DIY projects to date. The idea for the project is simple: what happens when you cross a supercar with the Cybertruck? You end up with a two-seater CyberRoadster.
Tesla owner David Andreyev, who goes by the username @Cyber_Hooligan_ on Twitter, has spent the last few months creating a Cybertruck-inspired version of the next-generation Roadster made from a salvaged Model 3 Performance. Starting with a Model 3 Performance is an inspired choice, considering that it is Tesla’s first vehicle that has a dedicated Track Mode.
A look at Andreyev’s YouTube channel, which can be accessed here, shows the meticulous build that the Tesla owner has implemented on the project car. What’s particularly cool about the CyberRoadster is the fact that it’s being built with parts that are also from other Tesla vehicles, like its front bumper that came from a new Model S. Recent videos suggest that the project car’s rear bumper will be from a new Model S as well.
The journey is long for Andreyev, so the completion of the CyberRoadster will likely take some more time. Despite this, seeing the Tesla owner’s DIY journey on such an epic build is more than satisfying. And considering that the CyberRoadster is evidently a labor of love from the Tesla owner, the final results would likely be extremely worth it.
There’s a lot of crazy Tesla modifications that have been done as of late. But some, as it is with a lot of things on the internet these days, have become more silly gimmicks than serious automotive projects. Fortunately, car enthusiasts like Andreyev, who just happen to also love electric vehicles, are taking it upon themselves to create one-of-a-kind EVs that would surely capture the attention of anyone on the road.
Check out the latest video in the CyberRoadster’s creation below.
