Why does the car remote key suddenly stop working?
1 Answers
Reasons why the car remote key suddenly stops working: Dead car battery: This causes the vehicle to fail to receive signals; the car remote key may also be out of battery, preventing the doors from unlocking. Signal interference: Car remote failure can occur due to high-power radio signals of the same frequency in the vicinity, which prevent the vehicle's signal receiver from detecting the radio-encoded commands sent by the remote key. This results in the remote failing to lock or unlock the doors. Potential sources of interference: Large outdoor LED displays, wireless call devices on construction site elevators, wireless video surveillance equipment, etc. Normally, compliant radio equipment should not cause mutual interference. However, if such devices malfunction, they may generate multiple continuous stray radio signals, which can interfere with nearby car remotes, leading to failure.
