What are the reasons why the Jetour X90 cannot detect the key?
2 Answers
Jetour X90 cannot detect the key due to reasons such as a dead key battery, poor battery contact, signal interference, or internal system issues. Dead key battery: When pressing any button on the key, if the key indicator light does not illuminate, it indicates the key battery is dead, and the key naturally cannot be detected. Poor battery contact: The key may also fail to work due to poor contact of the internal coin cell battery, preventing the battery from supplying power to the key. Signal interference: If the key cannot detect the vehicle, there may be a source of signal interference nearby, which emits interference signals that block the detection between the key and the vehicle. Internal system issues: Errors may occur after an internal system upgrade of the vehicle, causing the key and vehicle detection information to mismatch and preventing the vehicle from starting.
Last time my car key was like this too, no matter how much I pressed, the door wouldn't open, and the engine wouldn't start either - it was so frustrating! For the Jetour X90's keyless entry system, the most common issue is a dead key fob battery, where the weak signal can't reach the car. Other reasons include the smart key being blocked by metal objects like coins in your pocket, shielding the signal, or nearby strong interference sources like phones or transformers confusing the system. I've personally solved it by replacing the coin battery - just remember to keep keys away from electronics and avoid cramming them together in bags. Also, the car's signal receiver might be dusty or damaged, or the key chip could be broken from accidental drops - have the dealership read fault codes, and don't wait until the battery drains too, affecting startup.
