The package includes a set of three individual remote keys, offering a practical solution for households with multiple drivers or for creating a reliable backup. Each key is constructed from a combination of metal copper and plastic, identifiable by the model number HU92. A key differentiator is the choice of three radio frequency options – 315MHz, 433MHz, and 868MHz – allowing you to select the one that matches your car's specific remote entry system. The term 'semi-intelligent' denotes that this key provides remote locking and unlocking functions, distinguishing it from a basic mechanical key but not including the full transponder integration of a 'fully intelligent' key.\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 set of three keys, model HU92.\" 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 set is built from the stated materials and comes in a choice of operational frequencies to suit different BMW models and production years.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe key fob's construction uses two primary materials: metal copper and plastic. The metal copper is typically employed for internal structural components, electrical circuit boards, and the key blade itself, offering conductivity and strength. The plastic forms the external housing, providing the shape of the fob, the button overlays, and protection for the internal electronics. This material combination is standard for remote key housings, balancing durability with a manageable weight for everyday carry.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe source text does not provide specific physical dimensions for the key fob. As a replacement part designed for BMW vehicles, it is intended to be compatible with the form factor of the original equipment. The set containing three separate keys provides clear practical value, enabling different family members to have their own key or ensuring a spare is always available if one is misplaced. The model number HU92 is provided for precise product identification when ordering or seeking compatibility information.\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 set of three keys, model HU92.\" 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 fob serves a specific role as a functional replacement component for BMW cars, requiring correct setup to be used effectively.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eThis key is not designed for event-based or temporary use; it is a permanent vehicle accessory. Its primary professional context involves automotive locksmiths or dealerships who will programme the key to communicate with your specific car's immobiliser and central locking system. The choice between the 315MHz, 433MHz, and 868MHz frequencies is a critical technical step in this process, as using the wrong frequency will prevent the remote from functioning. This product supplies the physical hardware that the professional then configures.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eOnce correctly programmed and paired with your vehicle, this key becomes an integral part of daily use, providing remote access to your BMW. The three-key set is particularly useful for家庭s, allowing a primary key for the main driver and secondary keys for a partner or other licensed household members. Having multiple keys also mitigates the inconvenience and cost of being locked out if a single key is lost. The remote function adds convenience for locking\/unlocking the car from a distance, a standard modern expectation.\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 set of three keys, model HU92.\" 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 replacement part and the utility of having multiple keys from one purchase.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eAs a physical electronic device, the key fob itself does not 'reuse' in a consumable sense, but it is a durable component intended for long-term use. Maintenance is minimal, generally limited to battery replacement for the remote circuit when required and avoiding physical damage to the housing. The metal and plastic construction is designed to withstand the rigours of being carried daily. The core benefit is restoring full remote functionality to your vehicle, which is reused every time you drive.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis product is a suitable choice if you need a replacement or additional remote key for your BMW and have confirmed the required frequency. The inclusion of three keys in one set offers immediate value over purchasing single keys, especially for multi-driver households. The specified materials (metal copper and plastic) and the clear model number (HU92) provide concrete product identification. It addresses the practical need for a spare key or a replacement for a lost or damaged original, serving as the necessary hardware component before professional programming.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW CAS3 semi-intelligent remote car key fob set of three keys, model HU92.\" 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 set of three keys, model HU92.\" 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":"110xwn-eb","offers":[{"title":"Semi intelligent \/ 433Mhz","offer_id":53410403025239,"sku":"CJQC170993602BY","price":20.98,"currency_code":"GBP","in_stock":true},{"title":"Semi intelligent \/ 315Mhz","offer_id":53410403058007,"sku":"CJQC170993601AZ","price":20.98,"currency_code":"GBP","in_stock":true},{"title":"Semi intelligent \/ 868Mhz","offer_id":53410403090775,"sku":"CJQC170993603CX","price":20.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/9455\/7015\/files\/2ec76310-9704-4378-9011-16e12890860e.webp?v=1777180937","url":"https:\/\/shopprimex.com\/products\/bmw-car-key-cas3-semi-intelligent-remote-control-key-3-key-set-in-315mhz-433mhz-or-868mhz-frequencies-with-metal-copper-and-plastic-construction-model-hu92-replacement-or-spare-key-fob","provider":"ShopPrimex.com","version":"1.0","type":"link"}
