It is intended for owners who have lost their original keys, require a spare, or need a replacement for a damaged unit. The key is compatible with BMW's EWS (Electronic Immobiliser System) and must be professionally programmed to work with your specific vehicle's locking and engine immobiliser. It offers a practical alternative to sourcing a key directly from a BMW dealership, potentially providing a more accessible option for many owners of these now-classic models.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW 3 button remote key with straight silver blade and black fob for EWS system.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1511\/2025-10-02\/original-image\/31afab5e-b407-4efe-8fde-0bd0e28d1eb5.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis replacement key is built to match the specifications required by BMW's security systems from the era. Its construction and technical details are defined to ensure compatibility with the vehicle's electronics.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe key consists of a plastic remote fob housing the electronics and buttons, attached to a metal blade. The internal electronics include a radio transmitter operating on either 315MHz or 433MHz frequencies, which communicates with the car's remote central locking system. Crucially, it contains an ID44 transponder chip. This chip is an essential component that communicates with the vehicle's EWS immobiliser; without the correct, programmed chip, the car's engine will not start, even if the blade turns in the ignition.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe key has a straight blade design, referenced as an HU58 blade type, which is shaped to fit the ignition and door locks of the compatible BMW models. The entire unit has a listed weight of 0.06 kg. The remote fob section features three buttons, which are used for the standard remote locking, unlocking, and potentially boot release functions, depending on the vehicle's configuration and programming.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW 3 button remote key with straight silver blade and black fob for EWS system.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1511\/2025-10-02\/original-image\/32a8124a-7739-4c77-a678-cd39f118e837.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis key serves a specific function for maintaining or restoring access and operation to compatible BMW vehicles. Its use is tied directly to vehicle security and ownership.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eThe primary professional context for this key is automotive locksmithing and vehicle servicing. A qualified automotive locksmith or BMW dealership will use specialised equipment to programme the key's transponder chip and remote frequencies to your specific Vehicle Identification Number (VIN). This process syncs the key with the car's immobiliser and remote receiver. It is not a 'plug-and-play' item and will not operate any vehicle without this essential programming step.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor the owner, once professionally programmed, this key functions as a daily-use item for unlocking doors, disarming the alarm, and starting the engine of their compatible BMW.

The main maintenance consideration is the eventual replacement of the battery within the remote fob, a standard procedure for any keyless entry device. The metal blade is robust for turning in locks, and the plastic casing is designed to withstand typical handling.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis key is a specified replacement part that matches the technical requirements—frequency, chip type (ID44), and blade style (HU58)—for a clearly defined list of BMW models from the late 1990s and early 2000s. Choosing this product is based on verifying your vehicle's model year and series against the provided compatibility list (e.g., 1998-2005 3 Series E46, 5 Series E39, X5 E53 etc.). It provides a targeted solution for owners of these specific vehicles seeking a replacement key from a source other than a main dealer.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW 3 button remote key with straight silver blade and black fob for EWS system.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1511\/2025-10-02\/original-image\/6c86ac37-2c50-4782-b8bb-1795cb07bb26.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW 3 button remote key with straight silver blade and black fob for EWS system.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1511\/2025-10-02\/original-image\/8ebc93ed-57ba-41fc-a827-abf5fcc5b599.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW 3 button remote key with straight silver blade and black fob for EWS system.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1511\/2025-10-02\/original-image\/a3169a5b-be6b-4fd0-a368-f0c7f098a2f2.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW 3 button remote key with straight silver blade and black fob for EWS system.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1511\/2025-10-02\/original-image\/c3fa40c2-6066-4ffe-b6c9-85b581440abd.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW 3 button remote key with straight silver blade and black fob for EWS system.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1511\/2025-10-02\/original-image\/c54094e2-3997-4c41-acac-af9b399c9c3c.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"BMW 3 button remote key with straight silver blade and black fob for EWS system.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1511\/2025-10-02\/original-image\/f9575e1a-104f-4298-89cf-5af6a3d1b53e.webp\"\u003e\u003c\/div\u003e","brand":"5mn5u0-4f","offers":[{"title":"2 Small Keys \/ B434mhz","offer_id":57696155304318,"sku":"CJYD202692804DW","price":23.88,"currency_code":"GBP","in_stock":true},{"title":"1 Small Key \/ A315mhz","offer_id":57696155337086,"sku":"CJYD202692801AZ","price":23.88,"currency_code":"GBP","in_stock":true},{"title":"1 Small Key \/ B434mhz","offer_id":57696155369854,"sku":"CJYD202692802BY","price":23.88,"currency_code":"GBP","in_stock":true},{"title":"2 Small Keys \/ A315mhz","offer_id":57696155402622,"sku":"CJYD202692803CX","price":23.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/0150\/6942\/files\/8ebc93ed-57ba-41fc-a827-abf5fcc5b599.webp?v=1784257064","url":"https:\/\/lindenmere.co.uk\/products\/bmw-ews-3-button-remote-key-315mhz-433mhz-id44-hu58-straight-blade-key-replacement-for-1998-2005-bmw-3-series-5-series-7-series-x5-z3-z4-325-330-318-525-530-540-e38-e39-e46-e65-models","provider":"Lindenmere.co.uk","version":"1.0","type":"link"}
