BYD Qin Plus DM-i comes with a white remote key and a gray electronic key, both equipped with mechanical keys. The remote key features a groove at the bottom and supports remote driving functionality. Below are additional details: 1. Functions: Unlocks the vehicle's anti-theft system. Compared to traditional mechanical keys, the remote key uses electromagnetic waves to unlock the vehicle, offering superior security and convenience. 2. Composition of the car remote system: The transmitter consists of a transmission switch, transmission antenna (keypad), integrated circuit, etc. It includes an identification code storage circuit and an amplitude modulation circuit, with a button-type lithium battery on the opposite side of the circuit. The transmitter sends the identification code via shortwave modulation, which is then received by the vehicle's shortwave antenna.
I think the BYD Qin Plus DMI car key is quite high-tech in design. It features a black rectangular shape, resembling a mini remote control, with a size about the size of a palm and a thickness of around one to two centimeters. It feels quite light when held in hand. On the front of the key, there are three small buttons: lock, unlock, and trunk release. The buttons have a crisp tactile feel, minimizing accidental presses. The back of the key has a clearly engraved BYD logo, made of anti-slip plastic, which prevents it from easily slipping out when kept in a pocket. What I like the most is its keyless entry feature—just pull the door handle when nearby, and it unlocks, eliminating the hassle of taking out the key. The unlocking response is quick, sensing from several meters away. Additionally, the key can be paired with a mobile app for Bluetooth remote control, such as turning on the air conditioning in summer or preheating the seats in winter, making car usage more convenient. The key is powered by a standard button battery, which lasts about one to two years per replacement, proving to be quite durable.
