9. Important Fitment Note

BMW vehicles may use different door lock cylinder designs depending on chassis, production year, body style, and market configuration. A matching BMW 328i model name alone does not guarantee compatibility.

This listing is for the front left mechanical door lock cylinder only. It is not a complete door lock assembly, electronic door lock actuator, door handle, or remote key system.

For left-hand-drive vehicles, the front left position is the driver's side. For right-hand-drive vehicles, the front left position is the passenger side.

Please confirm the OE number, model year, chassis, body style, installation position, and physical design before placing your order.

Thank you for checking the fitment details before purchase.
