Misplaced your boat keys—or just want a backup stashed in the tackle box? Mercury’s Key Set-462 (87-897716462) is the exact pair your ignition switch was cut for, right down to the “462” code stamped on every factory cowling lock. Slide one into the dash switch or helm panel and feel that familiar click; carry the other ashore so a lost lanyard never keeps you off the water.

Why owners trust the genuine set

• Nickel-plated brass blades resist salt corrosion and slide smoothly into well-worn switches.

• Molded, over-size grips—easy to twist with wet hands or gloves, and they float long enough for a quick net-grab.

• Embossed Mercury “M” logo matches the original look on 1995-present 40-400 hp two- and four-stroke rigs.

• Pre-cut, ready to crank—no locksmith guesswork or trips to the hardware aisle.

Tuck a spare key into the chart plotter hatch or clip it to the engine stop-switch lanyard. One small precaution keeps a perfect day from turning into a tow-home. Genuine hardware, factory fit—exactly what your Mercury deserves.
