It serves as a functional substitute for lost, damaged, or additional keys, restoring remote central locking and, following professional programming, engine immobiliser bypass for ignition. The key integrates three physical metal blades within its construction, offering practical redundancy and convenience. It is supplied as a standalone unit, requiring specialist coding and cutting to become operational with your specific vehicle, a necessary step for all modern vehicle security systems.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent remote car key fob with three visible metal blades.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/248\/2025-10-02\/original-image\/318688d3-3669-4517-b27d-d04eea150b18.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe key is built to provide the core functions of the original BMW unit it replaces. Its design focuses on compatibility with the CAS3 electronic architecture and the inclusion of multiple physical access tools.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe key fob utilises a two-material construction: metal copper and plastic. The metal copper is employed in the internal circuitry and the three key blades, ensuring good electrical conductivity for the transponder chip and durability for the physical lock mechanism. The plastic forms the outer shell or housing of the fob, which is moulded to create the button interfaces and provide a protective case for the internal electronics. This combination aims to balance structural integrity with a functional form factor.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eWhile exact dimensional data is not provided, the product is designed as a direct replacement part. It is modelled to match the form factor of the original BMW CAS3 key fob, ensuring it fits comfortably in hand and aligns with the vehicle's ignition barrel. The inclusion of three separate key blades is a notable practical feature, allowing for the key to be used in multiple locks (doors, boot, glovebox) or providing spare blades in case of wear or breakage on one.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent remote car key fob with three visible metal blades.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/248\/2025-10-02\/original-image\/638ceb2c-fc9c-4923-8fb9-f450a4b00f3b.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThis key is intended for a specific automotive application, bridging the gap between physical and electronic vehicle access. Its use is defined by the technical requirements of the vehicle it is paired with.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eThe primary professional use case is with automotive locksmiths, car dealerships, and vehicle service centres. These specialists require a reliable source of blank key fobs that are compatible with popular systems like the BMW CAS3. This unit provides the raw hardware which they can then program, cut, and supply to the end customer as part of a key replacement service. Its selectable frequency option (315MHz, 433MHz, or 868MHz) is crucial for professionals to match the key to the specific model year and market version of the customer's BMW.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eFor the vehicle owner, this product becomes an everyday essential once professionally activated. It functions as the primary device for keyless entry via the remote buttons and, when inserted into the ignition, allows the car to start. The three blades mean the key can operate all the physical locks on the car. It is a solution for owners who need a spare key, whose original key is malfunctioning, or who have purchased a vehicle with only one key. The model number HU92 aids in ensuring the correct part is ordered.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent remote car key fob with three visible metal blades.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/248\/2025-10-02\/original-image\/c5321ba1-6f5c-4f89-89d5-9c9774c712cf.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe value of this product lies in its specificity and the utility it restores, rather than in standalone luxury features. It addresses a clear technical need within a defined ecosystem.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eAs a replacement part, its core benefit is restoring a lost function—the ability to access and start your vehicle conveniently. Once programmed, it is intended for long-term use. The metal copper blades are designed for repeated insertion and turning in locks. The plastic casing protects the internal electronics from everyday knocks. Maintenance is minimal; the key requires battery changes for the remote functions as per any standard key fob, and the blades may occasionally need cleaning if they become stiff in the lock.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eThis key is chosen for its confirmed compatibility with the BMW CAS3 semi-intelligent system, a critical factor that not all blank keys guarantee. The inclusion of three blades offers more immediate utility than a single-blade key. The clear specification of supported radio frequencies (315MHz, 433MHz, 868MHz) allows for an accurate match to your vehicle, preventing a common compatibility error. It provides the essential hardware component, with the understanding that professional service is required to complete the solution, making it a cost-effective starting point for key replacement compared to sourcing directly from a main dealer.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent remote car key fob with three visible metal blades.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/248\/2025-10-02\/original-image\/cc4d978e-bfb9-4f1f-b674-0ea08c3d4d95.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent remote car key fob with three visible metal blades.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/248\/2025-10-02\/original-image\/fc96d56b-c57a-4bf0-a59f-ffd5d0d22fca.webp\"\u003e\u003c\/div\u003e","brand":"test555ok6dygektw","offers":[{"title":"Semi intelligent \/ 433Mhz","offer_id":54154464493906,"sku":"CJQC170993602BY","price":21.88,"currency_code":"GBP","in_stock":true},{"title":"Semi intelligent \/ 315Mhz","offer_id":54154464526674,"sku":"CJQC170993601AZ","price":21.88,"currency_code":"GBP","in_stock":true},{"title":"Semi intelligent \/ 868Mhz","offer_id":54154464559442,"sku":"CJQC170993603CX","price":21.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1092\/8737\/5186\/files\/2ec76310-9704-4378-9011-16e12890860e.webp?v=1785620381","url":"https:\/\/vibehaven.fiorevale.com\/products\/bmw-cas3-semi-intelligent-remote-car-key-fob-replacement-with-three-key-blades-made-from-metal-copper-and-plastic-construction-compatible-with-315mhz-433mhz-and-868mhz-radio-frequencies-for-secure-vehicle-access-and-ignition","provider":"VibeHaven.com","version":"1.0","type":"link"}
