What to Do When the Nissan X-Trail Does Not Detect the Key?

[ArielFitz]

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.
