If you order these radio removal keys make sure the tips are completely smooth when you use them. Mine had small burrs on the shaped tip which caused them to get stuck. I had to unscrew the retaining clip from the radio to get them out. I filed them down afterwards and they were fine. There were no instructions either. You insert them into the holes then pull them gently sideways in opposite directions towards the doors. This flattens the spring clips and the radio pops out. You don't need them to put the radio back in again
