We offer multiple versions to cover the key forms of BMW across different years and configurations, including square, blade, smart, and card versions. Before placing an order, please select the corresponding style based on the shape of your original car key. If you have any questions, feel free to contact customer service for confirmation.

No. The shell is made of PC material with excellent signal penetration, and the structure is optimized for the RF characteristics of BMW keys to ensure no degradation in remote control range.

The shell is made of high-hardness PC material, with reinforced rib structures at the four corners and chamfered edges, effectively absorbing impact forces to prevent damage to the internal components of the key.

This product is only a protective case and does not include the original remote control chip, battery, or mechanical key. Please ensure you have the complete original key when making a purchase.

The key area is covered with a highly elastic TPU layer as thin as 0.3mm, which not only prevents dust and sweat from entering but also preserves the tactile feedback of the keys, ensuring precise response with every press.
