SUPALAND Keyless Entry Remote Start Key Fob Replacement for Chevy & GMC M3N-32337100 — 2-Pack Pre-tested

A drop-in replacement key fob from SUPALAND that arrives pre-tested with battery and electronics, ready for professional programming for compatible Chevy and GMC trucks.

If your original remote fob is lost, damaged, or its buttons no longer respond, this SUPALAND replacement reproduces the OEM FCC M3N-32337100 functionality for many Chevy Silverado, GMC Sierra, GMC Canyon, and Chevrolet Colorado models from mid-2010s to early 2020s. Each unit is assembled, pre-inspected with locksmith-grade tools, and ships with the battery and circuitry already installed so a locksmith or dealer can program it to your vehicle quickly.

Will this fob work with my Silverado or Sierra model year?

This replacement is designed to match the FCC ID M3N-32337100 and fits a broad list of trucks produced between 2014 and 2020 (and specific mid‑2010s to 2021 models for Canyon/Colorado). Always verify fitment with your vehicle’s year, make, model and part numbers before purchasing.

• Compatible models include Chevy Silverado and GMC Sierra 1500/2500/3500 (2014–2020).
• Also fits GMC Canyon and Chevrolet Colorado from 2015–2021 for listed part numbers.
• Cross-referenced part numbers: 13577770, 84540865, 22859392, 22859409, 13580082, 22881480.

How is this SUPALAND key fob prepared and what’s included?

Each key fob is quality-checked before shipping and arrives with the internal battery and electronics already installed, cutting out tedious assembly steps. The package contains two fully assembled remote fobs ready for professional programming.

• Two pre-tested key fobs per package.
• Batteries and internal electronics installed at the factory.
• Each unit validated using locksmith diagnostic tools.
• Ships ready for dealer or locksmith programming—no self-programming option.

What do I need to program the replacement remote?

These remotes must be programmed with specialized equipment by a qualified locksmith or at an authorized dealership. Self-programming is not supported, so plan for a short service visit to have the fobs linked to your vehicle.

• Programming requires locksmith or dealer tools—no DIY programming.
• Bring proof of ownership and vehicle VIN for security verification.
• Allow the installer to verify FCC ID and replace any lost keys in the vehicle’s security system.
• Programming time varies by shop but is usually a brief service appointment.

How does this replacement compare to an OEM fob?

SUPALAND’s replacement is built to meet the same functional expectations as an OEM remote with pre-installed components and thorough pre-shipment testing. It’s a cost-effective alternative when the original is unavailable, though final compatibility and full functionality depend on proper programming.

• Meets FCC M3N-32337100 specification for compatible vehicles.
• Pre-installed battery and electronics mirror OEM readiness.
• Two-pack offers immediate backup or replacement options.
• Requires professional programming to match vehicle security features.

Who is this for: This SUPALAND key fob set is for Silverado, Sierra, Canyon, and Colorado owners who need a factory‑style replacement without sourcing an OEM unit, locksmiths and fleet managers who want pre-tested spares, and anyone replacing a worn or lost remote—but who can get the fobs professionally programmed at a dealership or by a licensed locksmith.
