What to Do When the Nissan X-Trail Does Not Detect the Key?
2 Answers
If the keyless entry system displays "Key not detected," you can place the chip key against the keyless button and then start the ignition, which should generally allow the engine to start. When the vehicle control panel displays "Key not detected," it may indicate that the key battery is dead, and you should promptly replace it with a new large coin cell battery. If the keyless start system fails to activate, it might be because the key is too far from the ignition switch. It is advisable to place the key in the storage slot in front of the center console. For vehicles with keyless start systems, it is essential to protect the key carefully. Avoid frequent dropping, exposure to moisture, or demagnetization to prevent damage.
When encountering the issue of the X-Trail not detecting the key, my first thought is that the key battery might be dead. Replacing it with a new one should solve the problem—just buy a coin battery from the store and replace it yourself. Interference is another common cause, such as near cell towers or wireless devices. Try moving farther away or turning off other electronic devices. A weak car battery can also cause system malfunctions, so check if the vehicle battery is aging. Keeping a spare key is always a good habit; inserting it into the designated slot can allow for manual startup. If none of these solutions work, don’t hesitate to visit the 4S店 to check for issues like the antenna receiver. Safety first—don’t delay getting back on the road.
