How to Replace the Key Battery for Nissan X-Trail?

[Diane]

Press the button on the back of the key to remove the mechanical key. Use a flat-head screwdriver to open the battery cover, revealing the battery. Replace the key battery without touching the internal circuits and electronic contacts. Ensure the positive side of the battery faces the bottom of the casing when installing it, then close the cover. Finally, test the buttons to check if the functions are working properly. Here is some related information about the X-Trail key: 1. The battery model for the Nissan X-Trail remote key is CR2025. You can replace it yourself, but be careful not to touch the internal circuits and electronic contacts during the process, as this could damage the circuits and render the key inoperable. 2. After bringing the smart key into the car, the smart key system warning light will blink for 10 seconds and then turn off. If the smart key system warning light blinks green, it indicates that the smart key battery is nearly depleted. When the smart key battery is depleted or there are strong radio waves in the operating area, the operational range of the smart key system may decrease, and the smart key may not function properly.
