• Compatible models: Chevy Silverado / GMC Sierra 2014–2018 (1500, 2500, 3500)

How do I program these remotes and what tools are required?

Programming is performed with the included OBD LCD tool; no smartphone app or internet connection is necessary. You will need a working original car key for the OBD tool to authenticate; the tool locks to the first vehicle it programs but can add extra remotes for that same vehicle.

• Included OBD LCD tool performs on-vehicle programming
• Original functioning car key required for initial authentication
• Tool locks to the first vehicle used; not compatible across different vehicles
• Step-by-step user guide included to streamline the process

What comes in the box and how does it match OEM parts?

The kit contains everything needed for two working remotes plus the programming interface. Components are built to match OEM signals and part numbers so the remotes operate like factory units when programmed correctly.

• 2 keyless entry remote start control key fobs ready for programming
• 1 OBD LCD programming tool for quick setup
• 1 detailed user guide and 2 keyrings for attachment
• Manufactured to meet FCC ID M3N-32337100 and OEM specification 22881480

What should I be aware of before ordering and installing?

Plan ahead so you have a working original key available during programming and understand the OBD tool will bind to the first vehicle it is used on. If you lack a functioning original key or need remotes for multiple different vehicles, the dealer or a professional locksmith may be a better option.

• Requires a usable original key for OBD authentication
• OBD tool locks to first vehicle and cannot be reused for different vehicles
• Customer support available for setup questions or troubleshooting

Who is this for: This kit is ideal for truck owners comfortable doing a simple vehicle programming task who want a cost-effective replacement for lost or worn remotes. DIY-minded Chevrolet and GMC drivers with compatible 2014–2020 models will save time and dealer markup while keeping factory-style remote functions. If you don’t have an original key or need cross-vehicle programming, consider professional services instead.
