[LePresley]

The reasons for the non-responsive remote key of the Soueast DX7 include a dead battery and the presence of high-power radio signals of the same frequency in the vicinity. Below are the relevant explanations: 1. Dead battery: This causes the vehicle to fail to receive signals; a depleted car remote key battery prevents the doors from being unlocked. 2. Presence of high-power radio signals of the same frequency in the vicinity: This makes the car's frequency signal receiver unable to detect the radio-encoded commands sent by the remote key. As a result, the car remote fails, leading to situations where the doors cannot be locked or unlocked. 3. Additional information: Solutions for sudden malfunction of car remote keys: Every remote key comes with a mechanical key, which can be used to manually unlock the car doors.
