I just helped a friend research this a few days ago. The charging port for the BMW 730's LCD key is hidden along the bottom edge of the key. If you feel carefully, you'll notice a small indentation. You can use your fingernail to pry open the cover, revealing a USB-C port inside. Actually, it's much more convenient to use wireless charging normally—just place the key on the induction area in front of the cup holder, which is easier than searching for the port. Also, a reminder: never use a fast-charging adapter. I've seen someone use a 30W charger and end up swelling the key's battery. A standard 5V1A phone charger is the safest option. When charging, the key's screen will light up to display the battery level, which looks pretty cool.
When I first got my car, I also spent a while looking for the charging port. Later, I found it at the very bottom of the key, on the same side as the car key's switch button. Specifically, when you hold the key with the logo facing up, there's a black rubber strip about 5mm long at the bottom. Pry it open to reveal the Type-C port. I recommend keeping a short cable in the car, plugged into the USB port in the center console for easy charging. Actually, I later discovered an even more convenient method—using the car's built-in wireless charging feature. Just toss the key into the groove in front of the center armrest. If the key is completely out of power, the mechanical key is hidden beneath the side button of the key; just pry it open to retrieve it.
I remember last year when camping, my key fob ran out of battery and I was rummaging through the car. Turns out the charging port is at the bottom of the key—you need to pry open the protective cover with your fingernail to see it. Charging takes about an hour, and once fully charged, it lasts around 10 days. It's best to develop a habit: just toss the key on the wireless charging pad behind the gear shift while driving, saving you the hassle of finding the port. This design is genuinely practical, especially in winter when wearing thick clothes—no need to fish out the key. If yours is an older mechanical key, there's no charging port, and you'll need to replace the coin cell battery yourself, but the 730 should come with an LCD key fob.
