The Wacker Neuson 5100011455 Key is a genuine OEM Key designed for the RC110 single-drum soil compactor and the RD18, RD40, and RD45 tandem roller series. As a direct OEM replacement sourced through the Wacker Neuson parts program, this key is manufactured to the same specifications as the original component installed at the factory. Fitment spans a wide range of configurations across the RD18-80, RD18-100, RD40-130, RD45-140, RC110 ROPS, and RC110 CAB models. Verify your machine's model number and serial number before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction: — Manufactured to the exact dimensional tolerances required for correct engagement in Wacker Neuson ignition and access systems — no guesswork on fit.
- Drop-In Replacement: — Matches the original key profile precisely, allowing direct installation without modification to the lock cylinder or housing.
- Broad Fitment Coverage: — Compatible across the RC110 CAB and ROPS variants and a wide range of RD18, RD40, and RD45 tandem roller configurations, including open-drum and combination models.
- Protects Against Unauthorized Operation: — A correctly fitted, undamaged key ensures the ignition or access lock functions as designed, preventing inadvertent or unauthorized machine start-up on the worksite.
- Long-Term Durability: — Built from the same material grade as the original, resisting the wear and deformation that can occur with worn or substitute keys over repeated use cycles.
A key in a compaction machine serves as the primary physical credential for ignition or equipment access, engaging the lock cylinder to allow the operator to start or secure the machine. When a key becomes worn, bent, or lost, the lock cylinder may fail to turn cleanly or at all, taking the roller out of service until a correct replacement is fitted. Using the proper OEM key — matched to the exact cut and profile of the original — ensures smooth cylinder engagement and preserves the integrity of the machine's ignition and security system.
