What does the three lines on the X-Trail key mean?
3 Answers
X-Trail key three lines refer to the first line being the lock, the second line being the unlock, and the third line having different functions depending on the model. For the base model, it serves as a decoration with no additional functions, while for the higher-end model, it is the button to open the trunk, allowing for one-touch trunk opening. Taking the 2019 X-Trail as an example, its body dimensions remain unchanged from the previous model, with a length of 4675mm, width of 1820mm, height of 1722mm, and a wheelbase of 2706mm. The maximum power is 113kw, and the maximum torque is 204nm.
I remember driving my X-Trail for almost three years, and I always thought the three horizontal lines on the car key were just decorative. It wasn’t until later that I realized it was the trunk release button! A light press opens the trunk, which is super convenient when loading stuff. After shopping in the rain, there’s no need to manually unlock it, saving my clothes from getting wet. If the button responds slowly, it’s likely the key battery is low—just replace it with a new one. I recommend car owners test this feature regularly to avoid any hassle during trips. By the way, key maintenance is simple—just keep water from seeping in.
As a mechanic who frequently deals with cars, I've seen many X-Trail owners misunderstand the key design. The three horizontal lines refer to the trunk button, typically used to unlock or remotely open the trunk. Convenience was considered in the design, and holding it down may fully open the trunk door. To check if it's functioning properly, you can test whether the key signal is stable. For older models, if the button malfunctions, it could be a control unit failure. From a safety perspective, the trunk function is crucial—avoid pressing it randomly while driving. Replacing the key battery is a simple DIY task; just search for tutorials online to get it done.
