Mercury Mercruiser Ignition Numbered Key

Keep your Mercury outboard engine secure and functional with genuine Mercury Numeric Ignition Keys, available in key codes 1 through 10. Designed specifically for Mercury Marine Gen 1 side-mount control boxes and earlier ignition systems, these precision-cut keys ensure a perfect fit and reliable operation every time you start your engine.

Each key is coded to match the unique tumbler configuration of your ignition switch. Whether you’ve lost your key or are looking to replace a worn-out original, identifying the correct key is easy—simply match the number stamped on your ignition switch or existing key (e.g., “6”) to the corresponding numeric key code.

Made from high-quality, corrosion-resistant materials, Mercury’s ignition keys are built to withstand harsh marine environments. They’re compact, durable, and engineered to perform season after season. No guesswork, no generic substitutions—just the exact replacement you need to get back on the water.

These keys are not interchangeable across codes, so choosing the right number is essential. If your ignition switch is marked with a number between 1 and 10, this product is your direct-fit replacement solution. Ideal for marine mechanics, boat dealers, and recreational boaters alike, having a spare Mercury key on hand is a smart move to prevent unwanted delays on the water.
