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

Hkxydems replacement key fob kit lets you program two fully functional remote keys for compatible 2014–2018 Chevy Silverado and GMC Sierra trucks using the included OBD programmer in minutes.

If you need an extra remote, a fast replacement after losing or damaging a key, or a cost-effective option instead of a dealer visit, this kit provides two blank keyless-entry remotes plus an on-board diagnostic (OBD) programmer and a short user guide. The fobs match the button configuration and FCC ID used on many Chevy and GMC trucks from 2014–2018 (and certain 2015–2020 Colorado/Canyon models). Programming is done at the vehicle via the OBD port, so no special locksmith tools or dealer appointments are required, provided you already have at least one working original key.

How do I program these key fobs to my truck?

Programming uses the included OBD tool and follows a straightforward in-vehicle process. You must start with a working original key present to allow the OBD unit to pair with your vehicle. Once paired, adding the new remotes takes only a few minutes.

• Plug the OBD tool into the vehicle’s OBD-II port.
• Follow the step-by-step instructions in the included manual.
• Pair and verify each remote; typical setup time is 1–5 minutes per key.

Which trucks and key part numbers are supported?

This kit is compatible with many full-size Chevy and GMC trucks and some midsize models that use the same remote frequency and programming method. Confirm your original remote’s button layout and FCC/P/N to ensure compatibility before purchase.

• Compatible models: 2014–2018 Chevy Silverado 1500/2500/3500 HD and 2014–2018 GMC Sierra.
• Also fits: 2015–2020 GMC Canyon and 2015–2020 Chevy Colorado where applicable.
• Common identifiers: FCC ID M3N-32337100 (M3N32337100); P/N 13577770, 84540865, 13580082.

What’s included and what do I need before starting?

The kit ships ready to program and includes two blank keyless remotes plus the OBD programmer and accessories. You will need at least one working original key to authorize the OBD pairing; no dealer or locksmith visit is necessary.

• In the box: 2x keyless entry remotes, 1x OBD programmer, 1x user guide, 2x keyrings.
• Requirement: a usable original vehicle key for initial OBD pairing.
• Limitation: the OBD unit locks to the first vehicle it programs and cannot be used on other vehicles afterward.

Why choose this DIY replacement over a dealer or locksmith?

This kit is designed to save time and money while restoring full remote functionality. It’s ideal if you want to set up replacement keys at home or at a shop without scheduling dealership service and paying higher fees.

• Quick setup—complete programming in minutes at home or in a garage.
• Lower cost—avoids dealership labor and parts markup.
• Maintains OEM-style functions—locks, unlocks, and remote features match original operation.

Who is this for? Hkxydems’ key fob replacement kit is aimed at drivers of the listed Chevy and GMC trucks who need a spare or replacement remote, automotive technicians and repair shops that support quick key programming, used-car sellers preparing vehicles for resale, and vehicle enthusiasts performing modifications. If you do not have any working original key, or you need the OBD tool to be used across multiple different vehicles, this product will not meet those needs. Always verify your original remote’s button layout and FCC/P/N numbers against the kit’s compatibility list before ordering to ensure a smooth programming experience.
