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.

From the experience of seasoned drivers, it's quite common for Jetour cars to fail to detect the key. This is usually due to low battery in the key or the car not recognizing it properly; it could also be that the key hasn't been synchronized for too long, causing system logic confusion. Another thing to check is unstable battery voltage causing electronic system malfunctions. I've encountered a similar situation in a parking lot, and later found out the key signal was interfering with my phone being too close. The solution is simple: first try the spare key; if that doesn't work, synchronize in an area with stable signals; don't forget to check if the door switch is malfunctioning and affecting the response; make sure to stand within 1 meter of the door, not too far, and move slowly. Regular maintenance is key: clean the key contacts monthly and replace the battery every six months as a preventive measure.

The most common reasons for key fob not being detected are dead battery or strong interference. Like my car experienced, it worked right after a battery replacement; but would fail in strong magnetic fields. Other possibilities: internal rust/short circuit from water damage, loose/damaged receiver antenna contacts, or aging car battery causing insufficient system voltage. Quick checks: test with a spare key; press the key directly against the start button; turn off nearby electronics to eliminate interference. If signal is weak, avoid frantic button pressing to prevent lockout requiring manual override.
