CHIJUIYZKEY DIY Key Fob Replacement Kit for GMC Sierra & Chevy Silverado 2014–2018 — 2 Remotes + OBD Programmer

Complete DIY key fob replacement kit with two programmed remotes and an OBD LCD tool compatible with selected Chevy Silverado and GMC Sierra models.

If your factory key fob is lost, broken, or unreliable, this CHIJUIYZKEY DIY Key Fob Kit offers an affordable way to restore remote locking, unlocking, and remote start functions without a dealer visit. The set includes two full-function keyless remotes and an OBD programming tool with step-by-step instructions so you can program additional remotes for the same vehicle quickly at home or in your driveway.

Which vehicles will these remotes work with?

These remotes are designed for specific GMC and Chevy trucks from mid-2010s model years. Confirm compatibility by checking your vehicle’s year and OEM part numbers before purchase to ensure a match.

• GMC Sierra 1500, 2500, 3500: model years 2014–2018
• Chevy Silverado 1500, 2500, 3500: model years 2014–2018

• OEM references: FCC ID M3N-32337100; part numbers 22881480, 13577770, 84540865, 13580082

How does the DIY programming process work and what do I need?

Programming uses the included OBD LCD tool that connects to your vehicle’s OBD-II port; no smartphone apps are required. The OBD device guides you through the steps on its screen and locks to the first vehicle it’s used with, so additional remotes can be added to that same vehicle later.

• Required: at least one usable original car key for the OBD tool verification
• Included: OBD LCD programming tool, two remotes, two keyrings, and a user guide
• Limitation: OBD tool becomes vehicle-specific after first use

What functions and build details do these remotes provide?

Each remote replicates factory keyless entry and remote start functions according to OEM specifications. The housings and electronics match the original design so buttons, range, and responsiveness align with expected performance for these model lines.

• Functions: lock, unlock, remote start (when supported by vehicle), trunk and panic as applicable
• Construction: OEM-style shell and buttons for a direct fit
• Package: two complete remotes, OBD programmer, user manual, two keyrings

What should I expect after purchase and where to get help?

Inside the box you’ll find everything needed for at-home programming plus a clear guide to walk you through the process. If you encounter issues, CHIJUIYZKEY customer support is available to answer setup questions and help troubleshoot programming steps.

• Turnaround: program remotes in minutes once connected to the vehicle
• Support: dedicated customer service for setup and compatibility questions
• Save: avoids dealership programming fees and appointment wait times

Who is this for: This kit is aimed at owners of compatible Chevy Silverado, GMC Sierra, Chevy Colorado or GMC Canyon trucks who want a cost-effective replacement remote solution and are comfortable following straightforward OBD programming steps. It’s ideal for DIYers who prefer to avoid dealer markups, fleet managers replacing multiple remotes for the same vehicle, and anyone needing immediate replacement remotes with OEM-style fit and function.
