{"product_id":"snap-on-s-40-personality-key","title":"Snap-On S-40 Personality Key","description":"\u003cdiv\u003e\u003cp\u003eThe Snap-On S-40 Personality Key is a specialized diagnostic accessory that tells a Snap-On tool which vehicle communication profile to use, enabling OEM-specific tests and data access on supported makes. It is part of Snap-On’s Personality Keys lineup and appears in older catalogs as one of the European keys, grouped in bundles such as Bundle 10.4 alongside S-25, S-43, S-44, S-45 and S-62; the bundle notes Land Rover as a commonly supported make, indicating the S-40’s role for vehicles in that market segment. When installed in a compatible Snap-On diagnostic platform, the S-40 switches the tool into the correct protocol for the vehicle, enabling model-specific diagnostics and access beyond standard OBD-II. Like other Personality Keys, it is designed to be used with Snap-On diagnostic systems and is typically ordered through a Snap-On franchisee. In practice, the S-40 is used in service workflows where a vehicle requires a manufacturer-specific interface to access certain tests, coding, or data that are not available through generic diagnostic modes, making it a targeted part of the Snap-On keys ecosystem for European makes such as Land Rover.\u003c\/p\u003e\u003c\/div\u003e","brand":"Snap-on","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46259822625002,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-014.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/snap-on-s-40-personality-key","provider":"GTG Hardware","version":"1.0","type":"link"}
