I’m a car expert

AN AUTO wiz has revealed that car keyfobs have a secret way to allow drivers to get into their vehicles when the remote battery is low.

The TikTok creator shares car knowledge with her followers of more than 2million users regularly.

The car expert (@dongcheshijie) recently posted a video showing viewers what they should do if their car keyfob stops working because of a low battery.

She captioned the clip: "The car key is out of battery, how to open the car door?"

Hashtags were included in the caption like #howto, #cartok, #automotive, #driving, #skills, #knowledge and #tips.

The TikTok featured the car pro and her brother noticing someone seemingly trying to break into a car's window.

After she asked if the man was attempting to burglarize the car, he proceeded to show the woman a key and said: "This is my own car."

He explained that when he came back to his vehicle from the bathroom, his car door wouldn't unlock with his automatic key.

When the guy told the auto expert that he was going to break an expensive window on his car, she let him know she could help him get into his car using the keyfob and not spending a penny.

Showing a keyfob, the TikTok creator said: "There's a hidden mechanism behind our car keys."

"Just press and hold it to pull out the mechanical key inside," she explained.

The key port wasn't visible on the car's door handle so the woman demonstrated a technique of how to use the key to get inside.

Beneath the driver's door knob, she pointed out a tiny hole.

"Align [the key] with the small hole under the door handle," the TikToker said.

"Insert the mechanical key [and] pry gently."

After you remove the cover, you'll see a traditional keyhole for you to unlock the car.

From there, just insert the key, turn it and open the door using the handle.

The video has been viewed more than 80,000 times.

"Sister, I passed my test thanks to you," someone commented.

Another person added: "Sister gives some us some good practical advice!!"

A TikToker said: "So that's what that weird shaped fob key was for..."

"I was actually thinking about this happening to me the other day thanks sister," a user chimed in.
