If your GMC Sierra remote start is not working, the key fob might be the culprit. This small device sends signals to your truck to start the engine. Issues with the key fob often cause remote start problems. Let’s explore the steps to check the key fob.Battery Replacement
A dead battery is a common issue. First, check the battery’s charge level. If the battery is low, replace it. To do this, open the key fob casing. Use a small screwdriver to pry it open. Remove the old battery. Insert a new one, ensuring it’s the correct type. Close the key fob casing securely. Test the remote start again.Reprogramming The Key Fob
Sometimes, the key fob needs reprogramming. This ensures it communicates with your truck. To reprogram, sit inside your GMC Sierra. Insert the key into the ignition. Turn it to the “On” position, but do not start the engine. Press and hold the “Unlock” and “Lock” buttons on the key fob. Hold them for about 15 seconds. Release the buttons once the doors lock and unlock. This confirms reprogramming is successful. Test the remote start to ensure it works. “`Inspecting The Vehicle
Having trouble with your GMC Sierra remote start? Inspecting the vehicle can help. This section will guide you through checking key components. Let’s dive into the specifics.
Hood Latch Sensor
The hood latch sensor is a critical part of the remote start system. If the sensor is not working, the remote start won’t function. Here’s how to inspect it:
- Open the hood and locate the hood latch.
- Check for any visible damage or dirt.
- Ensure the sensor is securely connected.
- Clean the sensor with a soft cloth.
If the sensor looks fine, but the remote start still fails, you may need a professional to diagnose the issue.
Brake Pedal Switch
The brake pedal switch is another component to inspect. This switch tells the system the brake is engaged. If it malfunctions, the remote start won’t work.
Follow these steps to check the brake pedal switch:
- Press the brake pedal and see if the brake lights turn on.
- If the lights do not turn on, the switch might be faulty.
- Look under the dashboard to locate the switch.
- Ensure the switch is properly connected and not damaged.
If you notice any issues with the switch, consider replacing it. This simple inspection can save you from unnecessary trips to the mechanic.
Regularly inspecting these parts can help keep your GMC Sierra’s remote start system working smoothly.
Software And Firmware Updates

Diagnosing Electrical Problems
If your GMC Sierra remote start is not working, the issue might be electrical. Checking the electrical system can reveal what’s wrong. This involves looking at several components like fuses and wiring. Here’s how you can diagnose these issues.
Blown Fuses
Blown fuses are a common cause of remote start problems. A fuse protects your vehicle’s electrical system. If it blows, the circuit breaks and the device won’t work.
Here’s a simple guide to check for blown fuses:
- Locate the fuse box. It’s usually under the dashboard or in the engine compartment.
- Open the fuse box cover. Inside, you will find a diagram showing the fuse locations.
- Find the fuse linked to the remote start system. Check if it’s blown.
- Replace the blown fuse with one of the same rating.
Always use a fuse with the correct rating. Using a different rating can cause more damage.
Wiring Issues
Wiring issues can also disrupt the remote start function. Damaged or loose wires prevent proper electrical flow.
Follow these steps to inspect the wiring:
- Inspect the wires connected to the remote start system. Look for visible damage.
- Check for any loose connections. Tighten them if necessary.
- Use a multimeter to test for continuity in the wires.
- Replace any damaged wires you find.
Keeping the wires in good condition ensures your remote start works properly.
Diagnosing electrical problems might seem tough. But, with patience and the right tools, you can fix many issues on your own.
