Which vehicles and years will these remotes work with?

These remotes are designed for a specific group of General Motors midsize and full-size trucks. Confirm your vehicle year and part number before purchasing to ensure compatibility.

• Chevy Colorado and GMC Canyon: 2015–2020
• Chevy Silverado: 2014–2018 (1500, 2500, 3500)
• GMC Sierra: 2014–2018 (1500, 2500, 3500)
• OEM and cross-reference part numbers included for verification (22881480, 13577770, 84540865, 13580082)

How difficult is the DIY programming process with the included OBD tool?

The kit is built for owner installation and includes an LCD OBD tool with step-by-step prompts, so no smartphone app or dealer appointment is needed. You will need at least one working original key present during setup because the OBD tool authenticates against the vehicle.

• Plug-and-play OBD LCD tool guides you through programming
• Original working key required for initial vehicle authentication
• Tool locks to the first vehicle used; can program additional keys only for that same vehicle
• Clear printed user guide included for reference

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

The package contains two remote fobs that match OEM frequency and button layout, an OBD programming device, two keyrings, and a printed manual. The remotes carry the manufacturer FCC and OEM part identifiers to help you verify fitment with your vehicle.

• 2 keyless entry remote start control key fobs (OEM-compatible)
• 1 OBD LCD programming tool for on-site setup
• 1 printed user guide with step instructions and troubleshooting tips
• 2 metal keyrings for secure attachment

Are there any limitations or important notes I should know?

Yes—this solution requires a working original key for the OBD tool to authenticate the vehicle. The included OBD tool pairs to the first vehicle it programs and cannot be reused on an unrelated vehicle, although it can add more keys for the same vehicle.

• OBD tool locks to the first vehicle used—cannot program different vehicles
• Requires a usable factory key during setup for security authentication
• Not a dealer reflash—intended as owner-level replacement for compatible models
• Customer support available for setup questions or issues
