Changan car key above the 2× represents pressing twice can open the trunk, and pressing twice can automatically start the engine. The relevant information is introduced as follows: 1. Changan car key: Changan car key buttons include the lock button, unlock button, trunk open button, with keyless start function, that is, when the driver approaches the vehicle at a certain distance, the door lock will automatically open and release the anti-theft. 2. Take Changan CS75 as an example: Take the 2021 Changan CS75 Glory 280T manual elite model as an example, it is a compact SUV launched by Changan Automobile, with a length, width and height of 4650mm, 1850mm, 1715mm respectively, and a wheelbase of 2700mm, equipped with a 1.5T turbocharged engine, the maximum power is 131kw, matched with a 6-speed manual transmission.
I've been driving a Changan car for almost ten years, and I'm very familiar with the '2×' symbol on the key. It stands for pressing twice, usually on the key button, and is designed to activate the car-finding feature. After you park your car, press the lock button once, then press the '2×' button twice, and the car will flash its lights and beep a few times, helping you easily locate it in a large parking lot. I often use this feature in shopping mall or amusement park parking lots—when there are many cars, it saves time and hassle by preventing aimless wandering. Why is it designed this way? The manufacturer intended the double-press to avoid accidental triggers, like if the key is accidentally pressed in a bag, it won’t cause unnecessary noise. Battery consumption isn’t much of an issue, but if it stops responding after long-term use, remember to check the battery or key signal. Overall, it’s a thoughtful design—try it next time, and you’ll see how practical it is, especially for safety in nighttime parking lots.
When I first got my Changan car, I was also confused by the '2×' on the key. Later, I asked someone and learned that it means you need to press the button twice to activate a function. Specifically, you find the small button on the key, press it twice, and the car lights will flash with a few beeps—this is the vehicle locator feature. I remember the first time I used it in a crowded supermarket parking lot; with so many cars around, I couldn’t find mine. One press and it located the car—it felt magical and saved me a lot of hassle. As a newbie, I recommend trying this feature first while the car is locked—don’t worry about breaking anything. It’s quite handy, but be mindful not to disturb neighbors late at night. Also, the key battery might weaken over time, so regular checks are necessary to extend its lifespan and avoid failure when you need it most.
From a technical perspective, '2×' means pressing the button twice consecutively to trigger a specific function, such as activating the car-finder feature commonly found on Changan keys. After pressing twice, the car receives the signal and responds by flashing lights or honking, making it easier to locate. In terms of design, manufacturers opt for a double-press to enhance reliability and reduce the risk of accidental activation, such as in crowded environments where the key might be pressed unintentionally. This also involves wireless signal transmission—the first press might only lock the car, while the second executes the function command. Battery consumption isn't significantly high, but repeated use will slightly increase power drain. If the '2×' function doesn't respond, it could be due to signal interference or aging internal components in the key, and timely maintenance is recommended. This design is simple yet efficient, reflecting thoughtful details in automotive intelligence.
