Turns out your key fob might be smarter than you are. A TikTok clip from car creator Dom Giovanni (@car_connoisseur) has gone ballistic, racking up over 16 million views after revealing a hidden “remote start” sequence most owners have no idea exists.
In the video, Giovanni presses unlock once, then hits lock twice, holding the button on the second press. Suddenly, the car fires up, first on a Porsche, then on a Mazda and a Mercedes. The kicker? It seems to work across multiple brands, which is why drivers everywhere are now trying it on their own rides.
Does The Trick Actually Work?
Giovanni’s demo looks legit, and plenty of owners have confirmed the same sequence on forums for Toyota, Chevy, and GMC. In some cases, drivers even discovered their dealer never mentioned the function, assuming they needed a paid app to activate remote start. Others say their fob needed to “wake the car up” first by unlocking and relocking, but the end result was the same engine running from the driveway without stepping inside.
Of course, not everyone has had success. One bloke joked his Range Rover now just flashes “Go visit your dealer.” Others reported their older Civics and Daihatsus weren’t having it, which probably says more about their cars than the hack.
More Than Lock and Unlock
Key fobs have always carried hidden tricks. Consumer Reports notes that many can roll down every window with a double unlock, fold mirrors in by holding the lock button, or even reveal a mechanical key for when the battery dies. Tesla takes things further with Summon mode, parking itself while you stand outside looking smug.
The point is, most of us barely scratch the surface of what these little gadgets can do and the fact a random TikToker has to reveal it proves how much carmakers hold back from owners.
Why We Care About This
Owning a luxury car isn’t just about badge value or engine size anymore. The secret features built into your fob add real-world convenience and bragging rights.
Knowing them puts you one step ahead at the pub and means you’re not missing out on tech you already paid for. In a world where status is in the details, this is one hack worth testing.
