How to Replace the Key Battery for Nissan X-Trail?
4 Answers
Nissan X-Trail's key battery replacement method is as follows: Press the button on the back of the key to remove the mechanical key, use a flathead screwdriver to pry open the battery cover, then the battery will be visible. Remove the old battery for replacement, avoiding contact with internal circuits and electronic connectors. When installing the new battery, ensure the positive side faces the bottom of the casing, then close the cover. The Nissan X-Trail is a model under Dongfeng Nissan, with body dimensions of 4630mm in length, 1785mm in width, and 1685mm in height, and a wheelbase of 2630mm. In terms of exterior design, the X-Trail features a waistline that runs from the headlights to the taillights, giving it a sleek and fluid appearance. The uniform gaps between body panels and the integrated tailgate trim enhance the smooth transition between the tailgate and rear bumper, combining a sense of strength with elegance.
Last time I changed the battery for my X-Trail key myself and found it quite simple. First, check if your key is a flat type or a smart key. For the older flat type, just pry open the shell directly. For the smart key, press the small button on the key to pull out the mechanical key, then use a plastic pry tool to slowly open the key along the seam. Once opened, you'll see the coin cell battery, usually a CR2032 model. You can buy it at the supermarket for just over ten yuan. Remember to install the new battery with the positive side facing up, and test all the buttons to ensure the remote function works before snapping the shell back together. The whole process takes about five minutes, saving over two hundred yuan and a lot of time compared to going to the 4S shop.
Helped my neighbor sister replace the X-Trail key battery, here's a trick: there's a notch on the side of the smart key, just wedge a coin in and gently twist to open it. Be careful not to scratch the casing with metal tools—I usually use a bank card to pry it open. The battery model is written on the old battery, check whether it's CR2016 or CR2032 before buying. When installing the new battery, remember to place the side with text facing up—it won't work if installed backward. If you find dust inside the key after opening it, use a cotton swab dipped in alcohol to clean the circuit board contacts before reassembling. This task is truly zero difficulty—even my 70-year-old dad can do it himself. After replacing, remember to test the lock and unlock buttons—testing in the garage is the safest.
Practical Tips from an Auto Parts Store Owner: Different Nissan X-Trail key models use different batteries. Models older than 14 years use CR1620, while newer ones mostly use CR2032. Be extremely careful with the spring components when disassembling the key – if lost, the key won't close properly. You only need three tools: a new battery, a plastic pry tool, and a microfiber cloth to avoid leaving fingerprints. If the key doesn't work after battery replacement, it might need re-synchronization due to prolonged power loss. The steps are simple: sit in the car with doors closed, quickly turn the key on and off six times within 10 seconds ending in the ON position – successful synchronization is indicated by flashing hazard lights. DIY battery replacement costs about 8 yuan, while dealership quotes could buy you thirty batteries.
