5 Series New Energy version 2019 comes with a display key, while it is optional for other models. Currently, common key types on the market include mechanical keys, remote keys, touchscreen display keys, and smart wristband keys, with mechanical and remote keys being the most common. The BMW 5 Series is a mid-to-large-sized sedan with a 4-door, 5-seat configuration. Its dimensions are 5106 mm in length, 1868 mm in width, and 1500 mm in height, with a wheelbase of 3105 mm. In terms of power, the BMW 5 Series is equipped with a 4-cylinder, 2.0T, 184-horsepower turbocharged engine, paired with an 8-speed automatic transmission.

I'm absolutely obsessed with BMW's new tech, and the LCD key is just mind-blowing. It first debuted around the 2016 7 Series models, then expanded to the 5 Series, especially hybrid variants like the 530e. Nowadays, it comes standard on full-size SUVs like the X7 and coupes like the 8 Series. This key displays vehicle info such as fuel level and door lock status, and even allows remote activation of the AC or engine preheating – nothing beats warming up the seats before hopping in during winter. I spotted it as an option when test-driving the new M5, but remember, not all base 5 Series trims include it; you'll need higher specs or optional packages. Overall, flagship models like the 7, 5, X7, and 8 Series all embrace this high-tech feature, making daily driving more convenient and reliable.

Having driven the 7 Series for over two years, the display key has become my daily reliable assistant. It allows me to remotely check if the doors are locked or pre-start the engine to warm up the cabin, which is especially handy on rainy days. BMW has extended this feature to the 5 Series plug-in hybrid and the all-new X7, with the latter being more suitable for family trips. However, the key is slightly bulky and not very pocket-friendly; when charging is inconvenient, I have to resort to the spare key. Overall, it's practical, and I recommend confirming that the X7 or 8 Series, these premium models, come with it as standard when purchasing to avoid retrofitting later.

BMW's display key was first introduced with the 7 Series, and later became available for high-end hybrid models of the 5 Series, the entire X7 lineup, and the 8 Series sports cars. It can control functions such as locking the car and remote start. Some models require it as an optional extra or come with specific versions only.

As a homemaker, we find the X7's LCD key very convenient for taking care of our children. The key allows us to pre-activate the air conditioning to adjust the temperature, preventing the kids from catching a chill. The BMW 7 Series was the first to feature this, followed by some high-end versions of the 5 Series, but the X7 is the most practical for our family, with its clear lock status display. The large size is a drawback, but the functional benefits outweigh this.

If you're to buy a BMW, the display key is a highlight feature, available for the 7 Series, 5 Series hybrid, X7, and 8 Series. Ask about the optional upgrade when purchasing. Benefits include remote engine control for winter freeze protection, but it's expensive and the battery may run out. We recommend prioritizing the X7 or 7 Series for a fully inclusive experience.
