SUPALAND Replacement Key Fob & Uncut Transponder Key for Chevy/GMC 2014-2022 — FCC M3N-32337100, 315MHz, HU100 46 Chip

SUPALAND replacement key fob with an uncut transponder ignition key provides a complete, ready-to-program remote and blank key for compatible Chevrolet and GMC models from 2014–2022.

If your factory key fob is lost, damaged, or the battery won’t hold a charge, this SUPALAND assembly supplies a tested remote and a blank ignition key equipped with a 46 transponder chip. The remote matches FCC ID M3N-32337100 and operates at 315MHz; the uncut key uses the HU100 profile and B119-PT housing, making it suitable for a wide range of Silverado, Sierra, Colorado and Canyon vehicles. Note: cutting and professional programming by a locksmith or dealer are required before the key will start the vehicle.

Which vehicles is this remote and key compatible with?

This replacement set was designed to fit specific Chevrolet and GMC trucks and midsize pickups across model years listed by OEM fitment. Confirm your original part numbers and button layout before purchasing to ensure a match.

How do I install and get the key working in my vehicle?

The remote and blank key are supplied pre-assembled with battery and electronics installed, but they do not come pre-programmed. A qualified locksmith or dealership must cut the blank key and program the transponder and remote into your vehicle’s security system.
