The charging port for the BMW 730 key is located under the center armrest; additionally, there is a USB socket connector on the left side of the remote key; the new BMW 7 Series remote key can be charged either wirelessly or via USB. Wireless charging: The wireless charging device is located under the center armrest. Insert the remote key with the lock button facing upwards into the protruding clip of the charger under the armrest to initiate wireless charging. USB charging: Connect the remote key to a power source via the Micro-USB socket on the left side to charge. It takes approximately 2.5 hours to fully charge a depleted remote key using a USB cable.
The charging port location for the BMW 730 key is actually wireless charging—there's no exposed charging socket on the key itself. You need to place the key on the wireless charging tray in the front center console of the car—usually located below the center armrest or near the dashboard area. Simply place it gently, and it will automatically sense and charge. A full charge typically takes about two to three hours. If the key feels like it's draining quickly as it ages, remember to regularly clean dust off the tray to avoid poor contact. Avoid leaving the key in high-temperature environments to protect battery lifespan. If the key runs out of power, the car's dashboard will display a warning alert—address it promptly to avoid affecting remote unlocking functionality. Paying attention to these small habits can extend the key's lifespan.
I've worked on quite a few BMW 730 models, and their key fobs charge wirelessly without any charging ports. The charging spot is located on the interior center console's charging pad, specifically in the recess to the right front of the driver's seat. Ensure the tray surface is clean and free of debris when operating. This design eliminates plugging/unplugging hassles and offers better water and dust resistance. The battery is a rechargeable lithium-ion type that typically lasts several years with normal use. If you encounter in-car charging issues, it might be due to dust accumulation on the charging pad or circuit problems—avoid DIY key disassembly and let the dealership troubleshoot for peace of mind. For maintenance, check the key fob's battery status monthly.
The BMW 730's key fob actually doesn't have an external charging port, as it charges exclusively via the wireless tray inside the car. Located in the front center console armrest area, simply place it on the tray for induction-based charging. This design ensures both simplicity and safety, eliminating risks of water damage or port wear. During use, avoid letting the key come into contact with grease or metal objects to maintain stable signal transmission. If the key's battery runs low, the dashboard will flash a warning light after vehicle startup. Safety reminder: Never attempt to charge or touch the tray while driving. For maintenance, regularly wipe the tray surface with a soft cloth to ensure cleanliness and optimal performance.
