Before applying a specification

Confirm the engineering configuration

Different key or remote variants may ship with different coin cells even within the same model family. Match the actual fob, not just the vehicle name.

Year ranges here describe the cited chassis coverage, not every option sold under the same model name worldwide. The actual service manual and fitted equipment take precedence.
