I made a knob for the cubby lock with a stock knob, a Honda key purchased at radio shack and 24-hour two-part epoxy I already had for making model boats. I bought two knobs and keys to have spares for the inevitable screwup, but I got it perfect the first time. Very sturdy. I love having it. Makes getting into the cubby fast and easy. I wouldn't have the patience to use the ignition key every time.
