I just replaced the battery in my X-Trail key, and the process was quite simple. First, prepare a small flat-head screwdriver or a plastic card—avoid using metal tools to prevent scratching the key. Locate the small gap on the back of the key and gently pry open the plastic shell from the edge, being careful not to use too much force to avoid cracking it. Once open, you’ll see a small round battery, usually a CR2025. Slowly remove the old battery, noting the orientation of the positive and negative terminals. Head to a nearby supermarket to buy a new battery, and when placing it back, ensure the shiny side faces up or aligns with the original direction. Then, press the back cover firmly until you hear a click, indicating it’s securely fastened. Finally, test the unlock button to see if it lights up normally. The entire battery replacement takes less than five minutes, saving you tens of dollars at the dealership while picking up a handy skill. Key batteries typically last about two years, so regular checks can prevent sudden failures while driving.
