What Causes the Nissan Qashqai to Fail to Detect the Key?

[LaWeston]

Nissan Qashqai's failure to detect the key is caused by reasons such as a dead smart key battery, damaged smart box sensor, or signal interference. Below are the specific reasons: Dead Smart Key Battery: If the smart key battery is dead, replacing the battery will solve the issue. Damaged Smart Box Sensor: If it's a new car, this issue is unlikely but cannot be entirely ruled out. If the smart box sensor is indeed damaged, it can be replaced. If the car is under warranty, you can request the staff to provide a new smart box sensor. Signal Interference from Other Devices: If there is signal interference from other devices, moving to a location with better signal reception can resolve the problem.
