X AUTOHAUX 315MHz Replacement Key Fob Kit M3N-32337100 — 2-Pack 4-Button Transponder for Chevy & GMC Trucks

The X AUTOHAUX M3N-32337100 is a 315MHz replacement keyless entry remote with transponder keys designed to restore remote lock, unlock, panic alarm, and remote-start functions for compatible Chevrolet and GMC trucks.

This two-piece kit includes two fully assembled key fobs with batteries installed and two mechanical keys, built to match vehicles that use the M3N-32337100 FCC profile. Constructed from a mix of durable plastic and metal, each fob duplicates the factory four-button layout—lock, unlock, panic, and remote start—so you regain the convenience of push-button access and remote engine start on properly equipped trucks. Because these are aftermarket components with a transponder blade, a professional locksmith or dealer must cut and program the mechanical keys and synchronize the transponder/remote to your vehicle.

Will this remote fit my Chevrolet Silverado or GMC Sierra?

If your truck originally used an M3N-32337100 315MHz remote and has push-to-start capability, this replacement is made to match the factory button layout and frequency. Confirm vehicle years and model compatibility before purchase.

• Compatible models: Chevrolet Silverado (2014–2018), Chevrolet Colorado (2015–2021).
• Also fits: GMC Sierra (2014–2018) and GMC Canyon (2015–2021).
• Confirm FCC ID printed on your original fob equals M3N-32337100.
• Ensure vehicle is equipped with push-to-start if remote-start is required.

How do I program and activate these transponder remotes?

Programming requires cutting the mechanical key and syncing the transponder and remote functions to your vehicle’s immobilizer. This is a job for a qualified locksmith or dealership; success often depends on the vehicle’s existing keys and access to manufacturer programming tools.

• A working key fob is typically required to add or clone a new remote.
• Bring the new fob and mechanical key to a locksmith or dealer for cutting and programming.
• Try several reputable locksmiths if initial programming fails—procedures and equipment vary.
• No step-by-step DIY programming guarantee; professional service recommended.

What are the physical and functional features of these remotes?

The X AUTOHAUX remotes pair a rugged exterior with the essential button functions found on factory units, and each includes a transponder-equipped key blade. They ship with batteries installed so the remote buttons respond immediately after successful programming.

• Four-button layout: Lock, Unlock, Panic, Remote Start (when vehicle supports it).
• Materials: hard-wearing plastic shell with metal key blade for durability.
• Frequency: 315MHz, FCC ID M3N-32337100—match this to your original remote.
• Package contents: two keyless remotes (batteries included) and two mechanical keys.

What should I watch for before buying this replacement remote?

Double-check compatibility, confirm you can access professional key cutting/programming, and ensure one working key fob is available if your truck requires it to add new remotes. Aftermarket remotes are cost-effective but depend on correct programming to function with your vehicle’s security system.

• Verify model years and FCC ID before ordering.
• Confirm availability of a locksmith or dealer for cutting and programming services.
• Understand that remote-start will work only if the vehicle is factory-equipped for remote start.
• Replacement is sold as a two-remote, two-key kit—batteries are included.

Who is this for: Truck owners who need a direct-fit spare or replacement remote for compatible Chevrolet or GMC models and who can access professional key-cutting and programming services. This two-pack suits drivers who want a ready-to-program backup set or need to replace lost or damaged factory remotes without paying dealer pricing for factory parts.
