How to command start a Chevy Blazer?

Most Chevy Blazer models start with a push-button ignition when the key fob is inside the vehicle, and you can also remotely start the engine using the fob or the MyChevrolet app if your vehicle is equipped for it. This guide covers the standard inside-start method, remote start from the key fob, and app-based remote start, along with safety tips and troubleshooting.

Inside the vehicle: Using the push-button ignition

Requirements

To start from inside, you must have a functional key fob detected by the vehicle, your foot on the brake, and the vehicle in Park. The engine will start when you press the Start/Stop button once (no accelerator required).

Use these steps to start from inside the Blazer with the push-button ignition.

1. Seat yourself, ensure the gear selector is in Park, and place your foot firmly on the brake pedal.


2. With the fob inside the vehicle, press the Start/Stop button once to start the engine.


3. If the engine doesn't start, verify the fob is detected (try moving the fob closer to the Start button) and confirm the vehicle is in Park with the brake pressed.


4. Once started, you can adjust climate controls and settings as needed. To turn the engine off, press the Start/Stop button again.

Starting from inside is the quickest and most common method for Blazer owners, especially on models equipped with push-button ignition. If the engine stalls or fails to start consistently, there may be a weak battery, a faulty fob, or a sensor issue that warrants service.

Remote start using the key fob

Prerequisites

This method requires a Blazer with remote start capability, and the vehicle must be locked and parked. Some trims or packages include remote start as standard or add it via a connected services subscription.

Follow these steps to remotely start the Blazer with the key fob.

1. Ensure all doors are locked.


2. Press the Lock button on the key fob, then press and hold the dedicated remote start button (often the circular arrow) for about 3 seconds.


3. The engine should start and run for a set duration, typically around 10 minutes, depending on configuration. If it doesn’t start, try again or check the fob battery and range.


4. After it starts, you can use the brake and start button to drive away once you’re ready. If you want to stop early, press and hold the remote start button again or press the Start/Stop button (when inside the vehicle).

Remote start from the fob is convenient for preheating or cooling the cabin, but always exercise caution to avoid running the engine in enclosed spaces and ensure doors remain secure while you’re away from the vehicle.

Remote start via the MyChevrolet app

App prerequisites

The MyChevrolet app enables remote start and climate preconditioning on supported Blazer models, usually requiring an active connected services subscription (OnStar/GM Connected Services) and the vehicle to be online. Ensure the vehicle is enrolled and your account is authorized for remote start.

Use these steps to start the Blazer remotely through the app.

1. Open the MyChevrolet app and sign in with your account linked to the vehicle.


2. Select your Blazer from the vehicle list.


3. Tap Remote Start, then confirm your choice if prompted.


4. The engine starts and runs for the standard duration (commonly up to 10–15 minutes, depending on configuration). You can stop it from the app if needed by selecting Remote Stop.

App-based remote start provides cabin conditioning from anywhere with cellular service, but it relies on a live data connection and an active subscription. If you encounter issues, verify app permissions, account status, and vehicle connectivity.

Troubleshooting and safety considerations

Before tackling potential issues, review these common causes and best practices to keep everyone safe and the Blazer ready to start.

• The vehicle won’t start from the inside: check that the gear selector is in Park, the brake is pressed, and the key fob is detected. A weak fob battery or dead 12V battery can prevent cranking.


• Remote start not working: confirm the Blazer supports remote start for your trim, ensure the doors are locked, and verify an active connected services subscription if required.


• Key fob not recognized: replace the key fob battery and reattempt; ensure the fob is within range of the vehicle.


• App remote start fails: verify your account is linked to the vehicle, that the vehicle is online, and that your phone has a stable data connection.


• Security and safety: never remote start in a closed garage or enclosed space. Always verify the area around the vehicle is clear before starting remotely.

If problems persist after basic checks, contact your Chevrolet dealer or the GM Connected Services support line for assistance with authentication, fobs, or software updates.

Summary

The Chevy Blazer offers multiple legitimate ways to start up: the standard push-button ignition from inside the vehicle, remote start via the key fob, or app-based remote start through MyChevrolet (where supported). Each method requires basic readiness—presence of a functioning key fob, the vehicle in Park, and appropriate safety precautions. For ongoing remote capabilities, ensure your vehicle is properly equipped and connected to the GM/OnStar services and that all software and accounts are up to date. This combination provides convenient, hands-free starting options while maintaining essential safety controls.
