2021 325 comes with a card key. Here are the specific details about the BMW 3 Series: 1. Body dimensions: The body weight is 1465 kg, and the length, width, and height are 4734mm, 1811mm, and 1455mm respectively. 2. Powertrain: The long-wheelbase version of the BMW 3 Series is equipped with the new B-series 2.0T engine, with the same power output as the current 320i/Li at 184 horsepower, but the tail badge has been changed to 325Li. 3. Transmission: It is paired with an 8-speed automatic transmission. Additionally, improvements in lightweight design, thermal energy management, and fuel efficiency optimization contribute to the vehicle's power output.

I have driven the 2021 325, and the card key is usually not a standard configuration; the standard model comes with a traditional remote key, while the card key requires the optional Comfort Access package or other higher-tier options. BMW's digital key system includes the card key, which allows you to unlock the car and start the engine by swiping a credit-card-like thin strip on the door handle—a very convenient and modern feature, but it comes at an additional cost. For regular 325 owners, it's recommended to check the vehicle purchase contract or contact the dealer to inquire about specific configuration codes. Alternatively, you can use the BMW App with your smartphone as a substitute unlocking tool, which is ideal for tech-savvy users in daily use.

I have some knowledge about automotive technology. BMW's card key is based on NFC (Near Field Communication) technology and was available as an optional feature on the 2021 325 model, though not a standard one. The card key boasts a sleek and lightweight design, easily fitting into a pocket without taking up space, whereas the standard plastic remote key requires button operation. To confirm if your vehicle is equipped with this feature, you can decode the VIN number or check the manual. The advantage of the card key lies in its enhanced anti-theft capability and stylish appeal. However, if unavailable, connecting your via Bluetooth to the BMW App offers a convenient alternative for starting the car and controlling the air conditioning system.

Having been in the automotive circle for a few years, I can confirm that the standard configuration of the 2021 325 does not include a card key. The base version uses a conventional remote key, with the card key functionality available through additional paid packages like the Premium Comfort Package. The card key is convenient to use, allowing you to unlock the car and start the engine simply by touching the door handle. I highly recommend buyers check the original factory order or dealership documents to confirm if this upgrade was included. The card key design reduces keychain clutter and offers a modern feel, but those who didn’t opt for it need not worry—the remote key remains reliable and practical, perfectly suitable for daily driving.

A friend drives a 2021 325 with the standard remote key, while the card version requires an additional payment as an optional feature. The card key, resembling a credit card, allows for unlocking and starting the car with a simple swipe, which is pretty cool but not essential. She opted out of it and finds the mobile app just as convenient and free. The card is slim and portable, perfect for small bags and less prone to getting lost, with many girls appreciating its stylish and modern design. It's recommended that BMW owners check the specific sections in the BMW Owner's App settings or manual to confirm the options and decide if the investment aligns with their personal preferences.

Veteran Driver's Experience: The 2021 325 comes standard with a remote key, while the card key is not included by default; it is usually included in the high-end 325i or upgrade packages, simplifying operations through contact sensing. Compared to the mechanical keys of earlier cars, today's technology offers the convenience of card keys, which are easy to carry and hassle-free. If unsure about the vehicle's configuration, you can enter the VIN on the BMW official website to check or refer to the owner's manual for details about the card key. The trend in modern vehicles is digitalization, but the standard 325 meets basic needs perfectly well.
