BMW keys come in a total of 4 styles, namely the three-button, four-button, LCD screen, and card-style keys. Additional information: Three-button: The three-button key is the most basic and commonly used type of key in BMW vehicles and model introductions, mostly used in BMW 1 Series, BMW 2 Series, BMW 3 Series, and BMW X1 models. The functions of the BMW 3 Series key include: unlocking the car, locking the car, opening the trunk, etc. The mechanical key is inside the remote key. Four-button: The four-button version of the car key is mostly used in BMW 5 Series and 6 Series cars. The functions of the BMW 5 Series key include: opening the car door—long press can lower the windows; closing the car door—long press can raise the windows; opening the trunk; making the car lights flash and the horn sound. LCD key: The LCD key is mainly used in BMW 5, 6, and 7 Series. The BMW 7 Series key is large in size and features a display screen on the surface. Its functions include scheduling the air conditioning to turn on, checking the vehicle's locking status, and viewing the remaining range, among others.
Well, regarding the classification of BMW keys from the 1 Series to the 7 Series, I think we can discuss it from a technical perspective. The 1 Series, as an entry-level model, typically comes with a standard remote key—the kind with basic buttons, maybe a bit plasticky, simple and practical, but without many fancy features. The 3 Series, on the other hand, gets an upgrade, mostly featuring the Comfort Access smart key, which supports keyless entry and start, automatically sensing your approach to unlock the car—super convenient. The 5 Series, positioned as a mid-to-high-end model, often has more refined keys, possibly with a metallic finish and more comprehensive functions, like remote locking via an app. The 7 Series, as the flagship, uses the Display Key with a small screen, capable of showing vehicle status, remotely starting the air conditioning, or planning trips—extremely practical. Nowadays, BMW is also pushing digital keys, using smartphones to replace physical keys. For example, the 1 Series might support a basic version, while the 7 Series already comes standard with the advanced Digital Key Plus. In short, the key classification basically escalates with the series level, from basic to smart to luxury features, reflecting BMW's overall design philosophy—those who want hassle-free options can stick with the lower-end models.
