New ‘Gen2’ Tesla Keyfobs and More Discovered in 2021.4.2 Update by Hacker

Following Tuesday’s “Quadrupeddie” animal animation discovery, Twitter user and Tesla operating system (OS) hacker @greentheonly kept digging and discovered a few other exciting updates.

On Wednesday, @greentheonly found the Tesla Model Y manual now contains information about the 7-seater configuration. Also, there are new user interface (UI) translations in Finnish, Malaysian, and Hebrew, as well as release notes translated to Norwegian and Slovenian.

In addition, Green also found a range update for the Model Y efficiency package and two new “generation 2” key fob supports added.

“Two “gen2″ keyfob types added. One with 3 buttons (3/y?) and one with 5 buttons (refresh s/x?)”, said @greentheonly. Recently, FCC filings revealed Tesla was granted approval for a new Ultra Wide-band B Pillar Endpoint device.

Ultra Wide-band is a wireless technology used currently by Apple, suggesting Tesla could support Apple CarKey, allowing iPhones and Apple Watches to act as your key.

Also found, “headlights leveller is being replaced with a “virtual pitch sensor””, says the hacker, while you can now “install firmware updates from USB stick,” and not just over-the-air.

Green’s discovery comes from Tesla’s recent update 2021.4.2. The update also saw a significant change in the way the company stores release notes, moving from plaintext to a new binary format. While Green didn’t have a chance to unpack the new format as of yet, they claim that they will get to it in time.

While the recent news from Green isn’t anything mind-blowing, it does give us a little extra insight as to what kind of information Tesla keeps buried within its UI, waiting to come out on the navigation screen in the right circumstance.

In any case, the hacker has been offering sneak peeks at things buried in Tesla’s OS for quite some time now, and they’re not likely to stop anytime soon, to the benefit of Tesla owners everywhere.
