According to available information, the BYD Han key fob features four functional buttons: unlock button, lock button, trunk release button, and vehicle locator button. Their descriptions and functions are as follows: Unlock button: The button marked with an unlock symbol on the key fob is used to open the vehicle's doors and windows while activating the anti-theft system. Lock button: The button marked with a lock symbol on the key fob is used to secure the vehicle's doors and windows while activating the anti-theft system. Trunk release button: The button marked with a trunk opening symbol on the key fob is used to open the vehicle's trunk. Vehicle locator button: The button marked with a horn symbol on the key fob is used to remotely activate the vehicle's horn, helping owners quickly identify their vehicle's location. In addition to the traditional key fob, the BYD Han comes with a card-style key that enables NFC-sensing door unlocking. Simply place the card near the rearview mirror housing to effortlessly unlock the vehicle without needing to carry the bulkier traditional key fob.

As a tech enthusiast, I find the key design of the BYD Han quite cool. It has several buttons: in the center front are the unlock and lock buttons, one with an unlock icon and the other with a lock icon—just a light press and the car responds. Below that is a trunk button; a quick tap pops the trunk open, super convenient. Next to it is a small remote start button, great for warming up the car in winter or turning on the AC in summer, sparing you from discomfort when getting in. I guess it uses RFID technology, with a signal range of up to 10 meters. If the battery dies, just replace it with a CR2032 coin cell. When using it, it's best to avoid carrying other metal items that might interfere with the signal. Maintenance is simple—just wipe the buttons to prevent stains. Oh, and the key shell is smooth and lightweight, so you can toss it in your bag without worrying about accidental presses.

As a breadwinner, I use my BYD Han key to pick up my kids from school every day. Pressing the unlock button on top opens the car door instantly, so the kids don't have to wait; the lock button ensures safety by preventing accidental unlocks. The trunk button at the bottom is the most useful—it directly activates for loading shopping bags or miscellaneous items, while the remote start lets me preheat the seats in winter and ventilate the car in summer. Remember not to drop the key carelessly to avoid damage. If it occasionally malfunctions, check the battery or signal positioning. I find this key practical and hassle-free, and pairing it with the mobile app adds remote control functionality. When replacing the battery, just unscrew the cover with a screwdriver.

When I first got the car, I was curious about the functions of the BYD Han key. There are three main buttons: the top one is the unlock and lock button, press unlock to open the door, and press lock to close it; the middle trunk button opens the trunk with a single press for loading things. I learned about remote start by long-pressing the small button to preheat the engine. Common issues like sticky buttons might mean the battery is dead—just replace it with an inexpensive CR2032. When using it, press lightly, and avoid mixing it in your bag to prevent accidental starts—safety first.

As a fashion enthusiast, I adore the streamlined design of the BYD Han key, with its clear button layout: the symmetrical unlock/lock buttons on top are aesthetically pleasing and have a nice tactile feel; the slightly recessed trunk button at the bottom is easy to operate; the small side button is a bonus for remote start. When using it, I feel it complements the car's modern vibe, with quick signal response. A maintenance tip: regularly clean the key surface to prevent water stains, and replace the battery annually to avoid failure.
