MFK-024: MFK Mercedes-Benz Brass Blade — HU39 (10-Pack) Mercedes-Benz A, B, C, E, S Class and Sprinter — high-security HU39 profile

The HU39 is one of Mercedes-Benz's most widespread key profiles, appearing across a broad range of passenger and commercial vehicles from the late 1990s through to the mid-2010s. The MFK-024 delivers 10 precision-machined brass blades in this profile — enough to build test keys, mechanical keys, or transponder keys without having to reorder mid-job.

Brass construction gives a cleaner cut and longer blade life compared to cheaper zinc alloys, with dimensional tolerances that stay within spec whether you are cutting on a code machine or duplicating by hand. Combine with a matching GTL MFK head and a Mercedes-compatible chip for a complete, programmable key.
