Powder Coated Metal CNC Machined Car Key Housing For Automotive OEM Use

The CNC machined car key housing is a precision metal enclosure designed to protect internal electronic components while enhancing durability and appearance. Manufactured using advanced CNC milling processes, this housing features accurate dimensions, smooth edges, and excellent structural consistency, ensuring a perfect fit for automotive key assemblies.

The metal key shell is finished with high-quality powder coating, providing a uniform surface, strong adhesion, and enhanced resistance to wear, corrosion, and daily handling. Compared with traditional painting, the powder-coated finish offers improved durability, scratch resistance, and long-lasting color stability, making it ideal for automotive key applications.

Various metals such as aluminum or steel can be selected to meet strength, weight, and cost requirements. The housing design can be fully customized in size, shape, button openings, and logo details according to customer drawings or samples.

CNC machined and powder-coated car key housings are widely used for smart car keys, remote key fobs, and aftermarket automotive accessories. OEM and ODM services are supported for prototype development and mass production with stable quality control.
