This key was commonly used in the previous generation of BMW models, primarily found in older 5 Series, 7 Series, X3, X4, X5, and X6. Below are details about BMW's blade key: 1. Many newer BMW models feature this blade-style key design, which boasts refined craftsmanship and eliminates the need for aftermarket modifications. 2. BMW's latest smart blade key evolved from the original M3 color scheme upgrade. Meticulously engineered, this key combines ergonomic grip comfort with user-friendly operation while exuding luxury. Its moderate weight conveys premium solidity. Constructed from aluminum alloy and ABS materials with polished surfaces, it delivers exceptional tactile refinement. A special coating effectively prevents paint peeling and oxidation.

I've actually looked into this. The BMW blade key is particularly common among the M family. Performance models like the M5, M3, and M4 mostly come with this design, especially since the F90 M5 in 2017. Later, high-performance SUVs like the X5M and X6M also adopted it. It does feel flatter and sharper in hand compared to regular keys. However, newer models like the iX electric vehicle have started switching to card keys. If you want the traditional blade feel, it's safer to stick with the fuel-powered M Power models.
