MechanMagic Key Fob Remote Replacement for Chevy & GMC 315MHz Uncut HU100 Transponder 4-Button

MechanMagic replacement key fob remote with an uncut HU100 transponder key provides a ready-to-program, factory-style remote solution for select Chevrolet and GMC trucks (2014–2021) running 315MHz.

If your original key fob is lost, damaged, or no longer reliable, this MechanMagic assembly gives you a full replacement: a four-button remote (FCC ID M3N-32337100, P/N 22881480) running on 315MHz with a CR2032 battery included, plus an uncut B119 HU100 transponder blade (chip 46). The unit ships fully assembled and tested so locksmiths or dealers can cut and program the transponder and pair the remote to your vehicle. It’s designed for model-year compatibility with Chevrolet Colorado, Silverado, and GMC Canyon and Sierra trucks — confirm fit using your vehicle’s year and the part identifiers.

Which trucks will this MechanMagic remote fit?

This remote and key set covers many mid-2010s to early-2020s Chevrolet and GMC pickup models. Fitment depends on the factory remote type and transponder chip — always verify against your current FCC ID or part number.

How do I get this remote programmed and the key cut?
