There are several reasons why a car key suddenly stops working remotely: 1. The car is dead, preventing the vehicle from receiving signals; 2. Presence of high-power radio signals with the same frequency in the vicinity; 3. Interference from large outdoor LED displays, wireless callers for construction elevators on work sites, wireless video surveillance equipment, etc.; 4. Intentional human interference. Methods for maintaining a car remote key include: 1. Avoid placing it together with metal objects; 2. Do not leave the spare key inside the car; 3. Keep the smart key away from electronic devices; 4. Avoid exposing the key to high temperatures or contact with liquids.
