Key Fob Remote Replacement Fits 4 Button Chevy/GMC 2014-2019 - Easy

In this review the focus is a practical replacement option for owners of Chevy Silverado and GMC Sierra trucks from 2014 through 2019. The Key Fob Remote Replacement (FCC ID M3N-32337100) aims to be a low-cost, direct swap that arrives fully assembled with battery and electronics already installed; the single biggest reason to buy is the convenience of fast self-programming via the vehicle OBD port without visiting a dealer. For drivers who lost a fob or need a spare, this review tests whether it truly works as a no-fuss replacement.

Key Features

• FCC Compatibility: Matches FCC ID M3N-32337100 so it is intended to be electrically compatible with the listed Chevy and GMC models.
• Pre-installed Battery and Electronics: Arrives fully assembled and pre-tested, which saves time and avoids soldering or parts swap before first use.
• OBD Programming: Can be programmed using the vehicle OBD port with the included instruction guide, eliminating the need for dealer trips or mobile apps.
• Standard 4-Button Layout: Provides lock, unlock and panic by default, plus an optional remote start button that will work if the vehicle was originally equipped for remote start.
• Complete Kit: Ships as a one-set key kit with manual so owners have everything they need to attempt setup immediately.
• Affordable Replacement: Offers a lower-cost alternative to dealer key services, making it a practical value choice for many owners.

Who It's For

This replacement is best for owners of Chevy Silverado, Colorado, GMC Sierra or Canyon trucks from model years 2014 through 2019 who need a quick spare or a lost-key replacement and prefer to program at home. It suits users comfortable following a step-by-step manual and using their vehicle OBD port for programming rather than visiting a dealer.

It is not for vehicles that were not originally equipped with keyless entry or for buyers who expect dealer-level remote services or transponder rekeying included. Also, if you cannot access the OBD port or prefer professional programming, a dealer or locksmith service may be more appropriate.

Pros & Cons

Pros

• Pre-installed battery and electronics make it ready to program out of the box.
• OBD-based setup avoids mobile apps and dealer appointments, saving time and money.
• Compatible FCC ID and standard 4-button functions match original remote controls for the supported models.
• Customers report easy programming and good value for the price.

Cons

• Optional remote start button only works if the vehicle originally had that feature, so not a universal guarantee.
• Requires one original key to start the engine during installation, so you cannot use this if all keys are lost.
