Bomag 05755124 Ignition Key

The Bomag 05755124 Ignition Key is a genuine OEM replacement designed for an exceptionally wide range of Bomag equipment, spanning single drum rollers, tandem rollers, walk-behind rollers, pneumatic tyred rollers, reversible vibratory plates, trench compactors, refuse and landfill compactors, soil compactors, cold milling machines, recyclers and stabilizers, material feeders, and pavers. As a direct OEM part, this ignition key matches the original lock cylinder specification for each covered machine, delivering the same fit and function as the key supplied at the factory. Compatible models include the BW 213 D-5, BW 226 DH-5, BW 174 AP-4, BW 100 AD-5, BPR 75/60 D-3, BC 772 RB, BMP 851, BM 1000/35, MPH 122, RS 500, BMF 2500 S, and hundreds of additional Bomag platforms — making part number 05755124 one of the most broadly applicable ignition keys in the Bomag fleet. Sourcing a genuine OEM key ensures the cut profile and key blank material match your machine's original ignition switch exactly, avoiding the misalignment and premature wear common with non-specified substitutes.

Key Features

• OEM Cut Profile Accuracy — Genuine Bomag manufacture means the key blank geometry and cut depth match the original ignition cylinder specification, preventing the binding and cylinder damage that off-spec keys can cause.
• Direct Drop-In Replacement — This ignition key installs directly into the existing lock cylinder with no modification, maintaining the original keying arrangement across all covered platforms.
• Broad Cross-Fleet Fitment — A single part number covers an extensive range of Bomag equipment including BW-series single drum, tandem, walk-behind, and pneumatic tyred rollers; BPR and BPH reversible vibratory plates; BC-series refuse, landfill, and soil compactors; BM cold milling machines; MPH, RS, and BMF machines; the BMP 851 trench compactor; and more.
• Operational Continuity — A worn, broken, or lost ignition key can prevent a machine from starting and bring an entire work cycle to a halt; replacing it with the correct OEM key restores normal startup and shutdown operation immediately.
• Ignition System Integrity — Using a key matched to the original cylinder profile reduces internal tumbler wear over time, preserving the ignition switch and reducing the likelihood of switch replacement down the road.

The ignition key is the operator's primary interface with a machine's electrical starting system. When turned in the cylinder, it rotates the tumbler stack to close the ignition circuit, allowing the engine to crank and start; returning to the off position opens that circuit and shuts the engine down. A key that is worn, incorrectly profiled, or broken can fail to engage the tumblers fully, causing intermittent start failures, inability to shut the machine off cleanly, or accelerated wear inside the lock cylinder itself. Replacing a damaged or lost key with the correct OEM-specified part restores predictable, repeatable operation of the ignition circuit across every work cycle.
