How to Unfasten a White Plastic Clip?

[DeEmmanuel]

Tools needed for removing the clip, such as a small cross-shaped or hexagonal wrench, can be borrowed from an auto repair shop. Insert the corresponding tool into the slot opposite the expansion clip. Rotate the tool inserted into the slot counterclockwise until the clip becomes loose enough to be removed.

As an experienced auto repair technician, I think plastic clips may look simple but require skill to operate. Those white clips usually have a small tab in the middle - you need to press it with your fingernail or a thin pry tool. The key is to apply force vertically without tilting, otherwise you might break the tab. I've seen too many cases where people yank them out with brute force and damage the base, making repairs even more troublesome. Remember to clean the surrounding dust before operating, and if it's stuck too tight, apply some WD-40 lubricant. Actually, these clips are cleverly designed - the mechanism works like a retractable ballpoint pen, when pressed properly it will make a 'click' sound and pop out.
