Design

BMW key fobs used to be large black, clunky rectangles that looked a bit like an opener for bottles from a distance. They were simple but functional. Then BMW began to make them a little smaller and put a plastic case around the base of the key that made it look more attractive and a little less like an opener for bottles. This new design also minimized the rough edges of the keys that could poke through bags or pockets, and made the keys easier to hold.

BMW has since introduced the Display Key which puts all the functions of your car in your hand. The BMW key fob comes with small LCD screens which allows you to lock and unlock your vehicle, operate the air conditioning, and access the information about your vehicle. Even hybrid models can have remote parking!

If you're in need of an upgrade, you can get the same great function by using a BMW Digital Key. Simply use your smartphone to replace the BMW key fob and then unlock your car! This feature is available for 2021 and more recent BMW vehicles that are equipped with the iDrive 8 operating system.

Some BMW owners have reported that their cars were snatched by criminals using an amplifier for signal strength to boost the identification signals.
