How to Set BMW Display Key to Chinese Language?

[Joshua]

Locate the BMW Smart Display Key, which can display various vehicle status information. Bring the Smart Display Key close to your BMW vehicle. Find and press the unlock button. Locate the lock button and press it, and you will notice that the BMW Display Key has switched to Chinese language. The 2.2-inch LCD Smart Display Key can display vehicle status, available fuel/electric range, and other information. When equipped with the Display Key, it may include Comfort Access features such as automatic unlocking when approaching the vehicle, starting the engine, etc.

I just helped my dad adjust this last week. First, we need to check your key model. Press the small square button on the side to unlock the key screen, then quickly press the BMW logo button at the bottom three times to enter engineering mode. A bunch of small icons will pop up—swipe left or right with your fingertip to find the globe icon and tap into it. The third option from the top is the language setting. Key point: For keys after 2018, simply select Simplified Chinese. But for older LCD keys, it might be hidden deeper—look for 'Chinese' or 'Simplified Chinese' in the English menu. After changing, don’t forget to hold the logo button for 10 seconds to restart the key, otherwise it might get stuck in the English interface. If the welcome message on the car is still in English after the change, you’ll need to re-pair the key in iDrive to sync the language.

Actually, the key's language follows the vehicle's infotainment system language. The real setting is adjusted on the central control screen. Sit in the car, power on without starting the engine, press the OPTION button on the left side of the steering wheel to enter the quick menu. Use the iDrive knob to scroll right and select the settings icon. Then go to General Settings, choose Language & Region, and change the display language to Chinese before exiting. The crucial step: simultaneously hold down the key's unlock button and the BMW logo button for 10 seconds until the key flashes red, then release. The key will reboot and re-pair with the car's system, and the display will automatically switch to Chinese. Note that BMW models before 2017 may not support the display key feature across all series, so confirm your vehicle has Digital Key functionality before attempting this method.

Yesterday, the auto repair shop taught me a trick: key methods really differ by year. For newer models with touchscreens, you can change it directly on the key: swipe down from the top of the screen to bring up the settings menu (just like a smartphone), find Language, tap it, and select Chinese. For older models with physical buttons, you need to simultaneously press the unlock button and the trunk button for 3 seconds, wait for the key to flash yellow, then quickly press the logo button 5 times to access the hidden menu and change the language. A heads-up: if the time display shows garbled characters after changing, you'll need to visit the dealership to connect to a computer and reprogram it for a complete fix. Messing with it yourself might disable the remote start function. It's recommended to take a photo of the original settings as a backup before making any changes.

The setup steps are super simple: 1. Press and hold the unlock button in the top-left corner while the key fob screen is lit. 2. Tap the gear icon at the bottom after the menu appears. 3. Select the second 'Setting' menu. 4. Choose the 'Language' option. 5. Scroll to Chinese and checkmark it. A little tip discovered during testing: If you can't find the language option, the key fob system version might be too old. In this case, place the key fob against the induction area on the right side of the steering wheel (marked with a key symbol), then select Vehicle Settings > External Devices > Key Language Sync Update in the iDrive system. After changing, remember to leave the key fob in the car for half an hour for automatic matching, otherwise it might revert to English upon next unlock.

I've encountered even more complicated situations: when the key itself doesn't have a Chinese language option, you have to rely on reprogramming. First, go to the 4S dealership and have the technician connect the BMW ISTA diagnostic computer to the OBD port. Then, enter the key programming module and select the 32ZH code (which represents Simplified Chinese). During the operation, the key must be placed on the charging pad in the cup holder to maintain full battery. The reprogramming process takes about 20 minutes—don't move the car. After the modification, a new issue may arise: the weather forecast function on the LCD key might locate to Taiwan Province. In this case, you'll need to change the location to Mainland China in the mobile app for it to display correctly. If you find this too troublesome, there's also an unofficial workaround: search for 'BMW key Sinicization' on Taobao, spend 150 yuan to mail it for modification. However, there's a risk of malfunction—the factory modification is the most reliable.
