Keyless Entry System

These tiny, wireless devices can be tricky to use properly and often require a bit of education to master.

These functions aren't always clearly labeled on the fobs, so they can be confusing for new drivers. These features can be turned off so that they don't activate accidentally.

The process of setting up the digital key is a fairly complex procedure, and one that BMW assists with as part of its new vehicle delivery service. Senior Editor CR Knizek took around an hour to install the digital key on his BMW M440i xDrive. He had to remove his iPhone to complete the set-up.
