What kind of oil should be added if the key insertion and removal are not smooth?

[Hallie]

Add gasoline if the key insertion and removal are not smooth. Precautions for using car keys are as follows: 1. Storage: Do not place car keys together with mobile phones. Car keys use low-intensity radio waves, so they may not work properly under magnetic interference. If placed together with mobile phones for a long time, the frequency of the mobile phone may cause the smart key to malfunction. At the same time, avoid contact with strong magnetic fields, such as high-voltage lines, transmission towers, and other places with strong magnetic field signals. Try to avoid parking the vehicle in these areas. 2. Avoid dropping: Free fall is a nightmare for most precision electronic products, and smart keys are no exception. Therefore, handle them with care and avoid dropping or bumping them.
