It serves as a practical solution for owners who have lost a key, need a spare, or require a replacement for a damaged unit. The key is supplied as a blank, featuring a semi-intelligent remote control housed in a metal and plastic construction and is compatible with the three primary radio frequencies used across European markets. It includes three uncut physical key blades, providing multiple options for cutting or keeping as spares once the primary blade is programmed.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent replacement car key remote with three blank 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\n\u003cp\u003eThis replacement key is built to match the specifications required by the BMW CAS3 system, focusing on core functional and compatibility features.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe key combines metal copper and plastic in its construction. The metal copper likely forms the internal structural components and the circuit board contacts, ensuring reliable electrical connectivity and a degree of heft. The plastic mouldings create the external housing, button interfaces, and the blade housings, providing the familiar tactile feel and durability expected from an automotive key fob. This material combination aims to balance weight, durability, and manufacturing cost for a replacement part.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe key is identified by the model number HU92, which corresponds to its physical form factor and internal electronics layout. It is designed as a direct physical and electronic replacement for the original factory key. The inclusion of three separate blank key blades (HU92) means you receive additional physical keys, which can be useful if one blade becomes worn or if you wish to have spares stored securely. The product is specifically noted as a \"Type 0\" component, indicating its status as a base replacement unit requiring final configuration.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent replacement car key remote with three blank 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\n\u003cp\u003eThis key is intended for a specific automotive application, replacing lost or non-functional keys for compatible BMW models.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eThe primary professional use case is for automotive locksmiths, car dealerships, or vehicle repair centres. These professionals will use specialised equipment to programme the semi-intelligent remote's transponder chip to communicate with the vehicle's CAS3 immobiliser computer. They will also use a key cutting machine to precisely cut the supplied blank blades to match the unique pattern of your vehicle's door and ignition locks. This process is essential for the key to start the engine and operate the central locking.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor the vehicle owner, this key becomes a fully functional spare or primary key once professionally cut and programmed. It provides the convenience of having a backup, which can be crucial if your only key is lost or damaged. The multi-frequency remote (supporting 315MHz, 433MHz, and 868MHz) is designed to offer broad compatibility across different European BMW model years and regions, increasing the likelihood it will work with your specific vehicle once correctly coded.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent replacement car key remote with three blank 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\n\u003cp\u003eThis product offers a structured solution for a common vehicle ownership need, focusing on compatibility and providing essential components.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThe key itself, once programmed, functions identically to an original. The metal and plastic construction is designed for daily use. The semi-intelligent system means the remote handles standard locking\/unlocking functions. Should the physical blade become worn from prolonged use, having two additional blanks included offers clear value, as you can have a new blade cut without purchasing an entire new remote assembly, potentially extending the service life of the electronic fob unit itself.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis key assembly is a suitable choice because it bundles the necessary components: a compatible remote fob and multiple blanks. The explicit compatibility with the CAS3 system and the three stated frequencies (315MHz, 433MHz, 868MHz) provides clear technical specifications to check against your vehicle's requirements before purchase. For owners seeking a cost-effective alternative to dealership-original parts, this package provides the core hardware needed, leaving the specialised cutting and programming to a professional, which is a required step for any replacement key.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent replacement car key remote with three blank 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 replacement car key remote with three blank 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":"test333aoum1ir20s","offers":[{"title":"Semi intelligent \/ 868Mhz","offer_id":53720958304594,"sku":"CJQC170993603CX","price":21.75,"currency_code":"GBP","in_stock":true},{"title":"Semi intelligent \/ 433Mhz","offer_id":53720958337362,"sku":"CJQC170993602BY","price":21.75,"currency_code":"GBP","in_stock":true},{"title":"Semi intelligent \/ 315Mhz","offer_id":53720958370130,"sku":"CJQC170993601AZ","price":21.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/3383\/5346\/files\/2ec76310-9704-4378-9011-16e12890860e.webp?v=1781192928","url":"https:\/\/raq4ad-in.myshopify.com\/products\/bmw-car-key-replacement-remote-control-with-semi-intelligent-metal-construction-for-cas3-system-compatible-with-315mhz-433mhz-and-868mhz-frequencies-supplied-with-three-blank-keys-for-coding","provider":"LucentHub.uk","version":"1.0","type":"link"}
