The following steps can be taken to troubleshoot and solve the problem of electric vehicles not responding to key insertion after being exposed to rain:
1. Check and unplug the motor circuit protection switch or plug: New electric vehicles usually have switches or plugs near the motor as an over water protection device. After rain, these protective devices may automatically disconnect the circuit due to water ingress, causing the electric vehicle to fail to start. Try to find and unplug this protective plug before attempting to start the electric vehicle. If it can start normally after unplugging, it indicates that the problem lies here, and waterproof measures should be taken when riding in the future.
2. Electric vehicles that are naturally dried or exposed to sunlight: After being rained on, the wiring of electric vehicles may short-circuit due to moisture, resulting in the inability to start normally. Move the electric vehicle to a ventilated and dry place, open the hood, and let it air dry naturally. If conditions permit, the electric vehicle can also be exposed to sunlight to accelerate the evaporation of moisture. Please note that do not attempt to start or ride the electric vehicle until it is completely dry to avoid short circuits or other safety issues.
3. Check and clean the lock: If the lock rusts due to water ingress, it may also cause the key to fail to insert or turn smoothly. Try using pencil lead powder, alcohol, or gasoline to drip into the lock for cleaning and lubrication. These items can remove rust and impurities inside the lock, restoring normal use of the lock. After cleaning, turn the key several times to ensure that the lock can be opened and closed smoothly.
If none of the above methods can solve the problem, it is recommended to seek the help of professional maintenance personnel to diagnose the problem more accurately and make repairs. At the same time, in daily use, attention should be paid to regular maintenance and upkeep of electric vehicles to avoid similar problems from occurring.
