The car enthusiast said their BMW has a lock feature when it reaches 15 mph.

To activate the feature, the driver pressed the lock button on the driver’s side door for five seconds.

The tip works for drivers who may come to frequent stops and want to keep their cars locked throughout the drive.


The driver also changes the settings for their passenger side mirror when the car is in reverse.

To unlock the feature, the BMW driver put the car in reverse before changing the settings on the passenger side mirror.

The driver focused the mirror on the back-side tire to optimize parking visibility.

Immediately after adjusting the mirror, the driver placed the car in park.

The car will then adjust the mirror every time it is in reverse, the TikToker said.


The TikToker also adjusted the door unlock settings through the car’s key fob.

“Press and hold the unlock button and the lock button on the car key at the same time for five seconds,” the TikToker said.

When the feature is activated, drivers can adjust how many doors unlock when the fob is close to the door handle.
