Removing the signature BMW kidney grills is an easy procedure that varies depending on what model of BMW you're working with. Older models tend to require the removal of mounting screws, while newer models produced in the past decade are installed without mounting hardware.
Open the hood of your car and examine the area where the front grills are installed.
Remove the mounting screws if there are any visible at the top of the kidney grills. If there are plastic clips visible instead of screws, insert the flathead screwdriver between the clip and the surface and gently pry up to pop the grill out.
Slowly pull the grill out of place after you have unclipped it or unscrewed the mounting hardware.
