Can the BMW 5 Series be equipped with a liquid crystal key?

BMW 5 Series can be equipped with a liquid crystal key, but only the new energy models of the 5 Series come with a touchscreen liquid crystal key, while other models offer it as an optional feature. Taking the 2021 BMW 525li as an example, it is a mid-to-large-sized 4-door 5-seater sedan with body dimensions of 5106mm in length, 1868mm in width, and 1500mm in height, and a wheelbase of 3105mm. The 2021 BMW 525li is equipped with a 2.0T turbocharged engine and an 8-speed automatic manual transmission, delivering a maximum power of 135 kilowatts and a maximum torque of 290 Newton-meters. Its drive system is front-engine rear-wheel drive, with a double-wishbone independent suspension at the front and a multi-link independent suspension at the rear.
I've specialized in researching BMW car keys, and the 5 Series is fully compatible with the LCD display key. This key isn't just stylish—it allows remote engine start, pre-activation of air conditioning, and displays door status and remaining range on its screen. High-end factory models come with it as standard, but it can also be retrofitted at authorized dealerships, though it requires specialized pairing with the vehicle's system. However, note that modification costs aren't cheap; replacing with a genuine LCD key costs around 7,000-8,000 RMB and requires several days for system activation. Owners of older 5 Series models may face more challenges, as they need to verify overall electrical compatibility first. I've seen cases where people opted for cheaper aftermarket LCD keys, only to experience malfunctions like non-operational power windows—so it's crucial to have it installed at official authorized shops for reliability.
