Did you know that your car has multiple hidden functions that "90% of people don't know about"? Well, it turns out one of them is being able to access a secret key which will help you in an emergency. This will be news to many people, but the more you know about the safety features of your car, the faster you'll be able to act when you need them. Cong, who posts as @conggeshuoche on TikTok, shared some "how to's" when it comes to your motor - and the main one showed a "hidden mechanical key" that can be removed from your fob if your fob isn't working. He explains: "Insert it into this little hole under the doorknob, pry lightly", and then the handle will come off to reveal a keyhole which you can open the door from.
