[AddysonAnn]

Solutions for difficult door opening and closing: 1. Replace the new door stopper; 2. Lubricate the door hinge or lock with lubricant; 3. Adjust the position of the buckle and loop, use a tool such as a screwdriver to gently pry the buckle, adjust a little, close the door once, and test while adjusting until it is suitable; 4. Buy a bottle of rust remover to clean or use butter, evenly apply it on the inner lock hook and lock of the door, open and close the door several times to evenly spread the butter. Many new cars, due to good seals and good airtightness, may also have difficult door closing, which is normal and can be restored after a period of use.
