In Right-Hand Drive (RHD) Mercedes-Benz models, the RH front lock body is the “master” entry unit. It houses sophisticated sensors for Keyless-Go and proximity detection, ensuring the vehicle unlocks as the driver approaches. The assembly features a high-tensile steel latch and internal micro-switches that signal the Body Control Module to manage interior lighting and alarm status. For premium trim levels, this unit may also incorporate a Soft-Close motor that uses a worm-gear drive to quietly pull the door into the secondary latch position for a perfect seal every time.
