How to Start a Nissan X-Trail with Key System Malfunction?

Smart keys have relatively weak anti-interference capabilities and may occasionally malfunction. This can be improved by replacing the battery or cleaning the key's electrode contacts. Opening the smart key allows access to the car key. Using the mechanical key can help unlock the car door when the smart key malfunctions.
I've been driving a Nissan X-Trail for several years and once encountered a key system failure that prevented the car from starting, which was quite frustrating. That time, the key fob battery was dead, and the car couldn't detect the signal. I checked the owner's manual and found that the X-Trail has an emergency start procedure: first, press the key against the start button near the steering wheel for a few seconds until the dashboard lights flash, then press the start button to ignite the engine. If that doesn't work, some smart keys have a small metal mechanical key inside that can be pulled out and inserted into a small hole on the inner side of the driver's door handle or a mechanical slot in the center console to simulate turning the key and start the car. Remember to always perform this in a safe location, not at a dangerous intersection. If all else fails, use the spare key or call customer service for a tow truck. I've developed a habit of checking the key fob battery every six months and replacing it with a high-quality button battery promptly. Also, I avoid exposing the key to water or dropping it on the ground. These small measures can save a lot of trouble, so I recommend everyone to occasionally check the manual and keep some basic knowledge handy.
