This is so damn funny:
https://www.reddit.com/r/AutoHumor/s/Fb0grYBMm1She is visiting from out of town and borrowing her mom's car. She went some store and came out and got into someone else's car, just like her mom's, who left the key fob in it. So she was able to start the car and drive it away, despite it being the wrong car. She couldn't lock the doors, so she was buying batteries for her mom's key fob, thinking that's why her mom's fob would lock the doors on the wrong car she was in. That's when the police showed up, lmao.
