How Many Types of BMW Car Keys Are There?
3 Answers
BMW offers four types of car keys: the three-button version, four-button version, LCD version, and card-style key. Three-button version: The three-button key is the most commonly used basic key type in BMW models. It is primarily used in the BMW 3 Series, 1 Series, and X1. The three buttons, from top to bottom, are for unlocking the vehicle, locking the vehicle, and opening the trunk. Four-button version: The four-button key is mainly used in BMW 5 Series and 6 Series models. The first three buttons have the same functions as the three-button version, while the fourth button is for a flashlight lighting feature. LCD version: The LCD key is a highly stylish version among BMW keys. It features a 2.2-inch LCD screen and integrates multiple functions, including locking/unlocking the vehicle, opening/closing the tailgate, lighting, parking ventilation, and remote parking. Card-style key: The card-style key is BMW's most advanced car key, primarily used in models like the 3 Series, 7 Series, and Z4. To unlock or lock the doors, simply place the card within 5 cm of the driver's door handle. To start the vehicle, place the card on the wireless charging pad.
I remember driving BMWs for decades, when the car keys were just ordinary metal keys with remote buttons. Now it's completely different. BMW keys have evolved into several common types: first, the traditional remote key for ignition insertion; then the comfort access key, which allows unlocking and starting without taking the key out; even more impressive is the display key, equipped on certain high-end models like the 7 Series, featuring a small screen to show car information; and there's the digital key, which enables unlocking and starting via a smartphone app. These key designs are quite thoughtful—the comfort access key makes daily use convenient by eliminating the need to take it out of your pocket, while the digital key is ultra-modern with just a phone. With more key options available, long-time owners need to adapt to these new features, but safety and reliability remain the top priorities.
BMW key features are really cool! Beyond simple button keys, there are now three to four mainstream types: the basic version is a smart remote key with unlock buttons; the upgraded version is a comfort access key that uses sensing technology to open the car door when you approach; high-end models like the i-series or X-series come with a display key that can check real-time vehicle status such as remaining battery level; the most cutting-edge is the digital key, which supports one-touch control via NFC on Apple or Android phones. Each key technology competes in convenience and security, such as the digital key being more reliable against loss. I think this reflects BMW's leadership in smart technology, and in the future, it might go fully digital, reducing the hassle of carrying physical keys.
