Most newer GMC trucks come equipped with factory remote start GMC truck systems. You can check your owner’s manual or with your local dealer to see if your specific model already has this capability.

If not, aftermarket systems are readily available and provide all the same functions as an OEM setup. They’re relatively easy for professional installers to add on. I’d recommend going with a reputable brand for quality and compatibility with your vehicle’s electronics.

How to Use the Factory Remote Start

If your GMC truck has a factory remote start GMC truck system pre-installed, here are the basic steps to get it going:

  • Press and hold the remote start button on your key fob for 2-3 seconds. The parking lights will flash to confirm the command was received.
  • The vehicle will start and run for a pre-programmed length of time, usually 10-15 minutes. This allows the engine to warm up or the cabin to cool down to the preset temperature.
  • When the engine shuts off, it will re-lock the doors for security. You can also extend the runtime if needed by pressing another button command.
  • To drive off once it’s at the right temp, just unlock the doors with the keyless entry and get in – no need to insert the key.

Programming an Aftermarket System

Aftermarket remote start GMC truck systems require a bit more setup during installation. The technician will need to:

  1. Connect wiring harnesses to the vehicle’s computer and electrical components under the dash.
  2. Program compatible remotes or app controllers to the vehicle using a diagnostic tool. This pairs them to start the specific engine.
  3. Set parameters like run time limits, temperature thresholds, and arming commands.
  4. Test all functions to ensure smooth and safe operation before completion.
  5. Provide manual instructions for use and troubleshooting tips. Reprogramming may be possible later on too.

With an aftermarket system, you’ll want to carefully follow the manufacturer’s programming and setup instructions. Professional installation is highly recommended to avoid issues down the road.
