This solution allows for plug-and-play installation, without the need for electrical modifications or adapters.

Benefits of Choosing a Used Original Switch

Choosing a used central locking switch from a dismantled vehicle is a sensible compromise between cost and quality. An original Mercedes part maintains:

• consistent operation with safety and comfort systems,
• appropriate electrical and logical parameters,
• factory markings that facilitate part identification and selection.

This allows you to restore full central locking functionality without investing in expensive new components, while preserving the characteristic equipment typical of the Mercedes brand.

Selection, Compatibility, and Technical Support

Before purchasing, it is advisable to compare the markings on your old module with the specifications to ensure the switch will work with your specific Mercedes Citan trim level and year. Original manufacturer markings and available interchange numbers facilitate precise part matching to your vehicle.
