What does 2× mean on the Changan key?
2 Answers
The 2X on the car key means pressing it twice to open the trunk. The specific functions of the car key are as follows: 1. Remote start button: The car key has a button with a circle and 2X, which represents the remote start function button. Pressing it twice will automatically start the car if it is within a certain range, achieving the effect of remote start. 2. Vehicle lock button: Pressing this button once will lock the car's doors and windows, activating the lock function. 3. Vehicle unlock function: Pressing this button can unlock the locked vehicle, allowing the doors and windows to be freely opened after unlocking. 4. Trunk open button: The symbol for this button is 2X and a rear car logo. Pressing this button twice will automatically open the car's trunk.
When I see the 2× mark on the Changan key, I think it actually represents a 'double-click function,' meaning you need to press the same button twice in succession to activate the operation. For example, on a car remote key, especially the trunk release button, pressing it once might only flash the lights to indicate readiness, while actually opening the trunk requires a second press. This design is primarily for safety, preventing accidental unlocks from touches in a bag or pocket, which could lead to car theft or items falling out. In some Changan models like the CS series, this is commonly seen on the trunk control button. I've also used similar keys myself—initially, I was confused when pressing once didn't work, but after learning, I got used to the double-click habit. In fact, many modern car models have added such anti-misoperation mechanisms. While it might seem inconvenient at first, it enhances protection in the long run. If the key has other issues, like slow response, you can check the battery or clean the contacts to maintain sensitivity more effectively.
