Sea-Dog Blank Replacement Ignition Key 420399 for Three Position Ignition Switches

The Sea-Dog 420399 is a blank replacement key made to work with Sea-Dog three position ignition switches, including the standard ignition-start switch and the magneto-style ignition switch. It is designed as a replacement for a lost or worn key so the ignition switch itself does not need to be replaced. The key is uncut (blank) and intended to be cut to match your existing switch, or ordered as a spare to keep on hand.

Sea-Dog three position ignition switches that use this key are built for off, ignition, and start functions, feature a 13/16 inch diameter long shaft for a maximum panel thickness of 1-1/8 inch, and are constructed of stamped brass. The switches ship standard with two keys, and this blank lets you add a spare or replace one that has been lost.
