It serves as a functional hardware component for owners needing a spare, a replacement for a lost key, or an additional key for shared vehicle access. The key is supplied as a complete unit featuring three physical keys and is available configured for the 315MHz, 433MHz, or 868MHz radio frequencies used by BMW for remote central locking. Constructed from metal copper and plastic, it matches the general material specification of original equipment. Important to note is that the key is supplied uncut and unprogrammed; activating it for use with your vehicle requires separate professional services for blade cutting to match your ignition and electronic programming to sync with your car's immobiliser and remote locking system.\u003c\/p\u003e\n\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 metal keys\" 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\n\u003cp\u003eThe key is identified by the model number HU92. Its design centres on compatibility with BMW's CAS3 electronic architecture, which manages vehicle access and immobilisation. The inclusion of three keys in a single package is a notable feature, providing immediate spare capacity.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe key utilises a two-material construction. Metal copper is employed for the key blade and likely internal electronic contacts and circuitry, chosen for its durability, conductivity, and machining properties. The outer casing, buttons, and surrounding fob structure are made from plastic, which houses the electronics, provides user interface points for the buttons, and gives the key its overall form factor. This combination aims to replicate the tactile feel and heft typical of modern car keys.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eWhile exact dimensional measurements are not provided, the product is described as conforming to the 'semi-intelligent' style. This indicates a key fob that integrates buttons for remote functions (like locking\/unlocking) but may lack a full integrated display or advanced smart features. The critical fit consideration is electronic, not physical: you must select the correct frequency variant – 315MHz, 433MHz, or 868MHz – that matches your particular BMW model's factory setting for the remote central locking system to ensure wireless signal compatibility.\u003c\/p\u003e\n\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 metal keys\" 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\n\u003cp\u003eThis key is a direct hardware replacement part. Its primary use is to restore or expand access to a BMW vehicle that uses the CAS3 system when an original key is lost, damaged, or when an additional key is desired.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor automotive locksmiths, car dealerships, or vehicle key replacement services, this product serves as a blank OEM-style key fob. Professionals can source the correct frequency variant based on the vehicle's VIN or model year, then cut the metal blade to match the car's lock cylinder and program the transponder chip and remote to communicate with the vehicle's CAS3 module. It provides a reliable parts solution for their service offering.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor the vehicle owner, this key becomes a functional spare once professionally prepared. It can be used for daily driving, kept as a secure backup, or given to another family member for shared car access. Having three keys from one purchase allows for one to be cut and programmed for immediate use, while the remaining two can be stored securely as future spares or for other purposes, offering long-term practicality.\u003c\/p\u003e\n\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 metal keys\" 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\n\u003cp\u003eThe value of this product lies in its role as a compatible, multi-key component that addresses a specific need for BMW owners within the CAS3 system ecosystem.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eAs a physical key, it is inherently reusable. The metal and plastic construction is designed for repeated insertion into the ignition and handling. Maintenance is minimal, typically involving only battery replacement for the remote transmitter when needed, and care to avoid physical damage. The availability of three keys in the package extends the product's utility and potential lifespan for the owner, as spare blades are on hand.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eChoosing this key is based on a confirmed need for a CAS3-compatible BMW key. The decision factors are its specified compatibility (BMW, CAS3, specific frequencies), the inclusion of three keys offering better value than single-key packs, and its material construction which aims for parity with original components. It is a solution for a defined problem – replacing or adding a key – rather than an upgrade. The buyer's responsibility is to ensure the correct frequency is selected and to factor in the necessary professional cutting and programming costs to make the key operational.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent remote car key fob with three metal keys\" 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 metal keys\" 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":"test33320y9r4qz7o","offers":[{"title":"Semi intelligent \/ 315Mhz","offer_id":57685505638744,"sku":"CJQC170993601AZ","price":18.0,"currency_code":"GBP","in_stock":true},{"title":"Semi intelligent \/ 868Mhz","offer_id":57685505671512,"sku":"CJQC170993603CX","price":18.0,"currency_code":"GBP","in_stock":true},{"title":"Semi intelligent \/ 433Mhz","offer_id":57685505704280,"sku":"CJQC170993602BY","price":18.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/7153\/3144\/files\/2ec76310-9704-4378-9011-16e12890860e.webp?v=1783708290","url":"https:\/\/h7brdc-4f.myshopify.com\/products\/bmw-car-key-cas3-semi-intelligent-remote-control-key-fob-with-three-keys-compatible-with-315mhz-433mhz-and-868mhz-frequencies-constructed-from-metal-copper-and-plastic","provider":"PrimePulse.uk","version":"1.0","type":"link"}
