Which BMW Series Comes with the Blade Key?

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.

Just helped a friend pick up a used M8 last week and paid special attention to this. BMW's blade-shaped key is primarily used in top-tier performance vehicles, especially coupes and SUVs tuned by the M division. Current models like the G80 M3 or F92 M8 come with it as standard, and even mid-size performance SUVs like the X3M/X4M are equipped with the same key. The most distinctive feature is the metal casing with M tricolor stripes, being almost half as thin as regular keys. It's worth noting that some standard 5 Series with optional M packages can also be fitted with it, but this is an aftermarket customization, not a factory standard.

A master technician with 10 years of BMW experience tells you: Look for the M badge. All M Power models under the G-generation platform now come with blade-style keys, such as the new M4 Competition and X3M, where the edges of the sports version keys are made as sharp as a blade. However, note that since 2019, top-end regular 7 Series and X7 models have also quietly switched to similar slim keys, just without the M badge. The easiest way to confirm is to check if the key has the tri-color M emblem—if it does, it's definitely an M family member; if not, it might be a modified regular version.

As a car enthusiast, I've collected seven blade-style keys. From the new M2 to the older M6 models, the most iconic is the original F10 M5 version with a display. Currently, most authentic M cars available in dealerships come with them, including the newly launched XM hybrid SUV which continues the blade design. Among non-M models, only the 7 Series 760Li and i8 sports car have used similar versions. The second-hand market can be particularly confusing, so here's a tip: genuine ones always have the M logo engraved on the side, while counterfeit versions tend to have shallower diamond patterns.

When I was researching car purchases, I checked official website data. The blade key is considered a performance identifier within BMW's system. Currently sold models like the M3 Touring and M4 Convertible in the coupe series all come with it as standard. It's about 20% shorter in size than regular keys, with noticeably prominent edges when held. However, starting from the 2022 X5 model, even the top trim has eliminated physical keys. So if you want to experience the metallic blade feel, I'd recommend prioritizing older platform performance cars like the M5 that haven't been updated yet, or simply look for a used F82 M4.
