If you have the OnStar Guardian app or a branded app like myChevrolet, myBuick, myGMC, or myCadillac, you can unlock your car directly from your phone.

Start by opening the app and signing in using your account details. Look for the “Remote Commands” section and select “Unlock My Vehicle.” Confirm the action when prompted. OnStar will send a signal to your car to unlock the doors within seconds. This method is the fastest and most convenient, especially if your phone is charged and connected to the internet. If you need help, customer service is available online and by phone.

If you don’t have the app installed, you can still get help through OnStar’s website. Use a smartphone or computer to visit www.onstar.com. Click on “Sign In” at the top right corner and enter your username and password. Once logged in, navigate to the remote services section. There, you’ll find an option to unlock your car. Follow the steps, and OnStar will send the signal to your vehicle. Make sure your internet connection is stable to avoid delays.
If you don’t have internet access or are unable to log in, calling OnStar is a reliable option. Dial this number using any phone. When prompted, choose to speak with a representative. Explain your situation and provide your account information. You may need to answer a few security questions to verify your identity. Once verified, the advisor will send a remote unlock signal to your vehicle. Stay near your car and wait for the confirmation signal.
In some cases, a window may be cracked open, or the vehicle may still be running. If it’s safe to do so, try reaching the blue OnStar button inside the car, usually located on the rearview mirror or dashboard. Press the button and wait for a connection to an OnStar advisor. Tell them you’re locked out and request a remote unlock. Only attempt this if it doesn’t put you in danger or damage the vehicle. Do not break a window to reach the button.
Getting locked out of your vehicle is never fun, but OnStar gives you fast, safe options to get back inside. You can use the mobile app or log in to the OnStar website to send a remote unlock command. If those options are not available, you can always call OnStar directly. In rare cases, you may be able to press the in-vehicle button yourself. After you complete the steps, OnStar will send a signal to unlock your car. If the unlock fails, they may connect you with roadside assistance. Help is just a few clicks or a call away.
GetHuman has been working for over 10 years on sourcing information about big organizations like Comcast in order to help customers resolve customer service issues faster. We started with contact information and fastest ways to reach a human at big companies. Particularly ones with slow or complicated IVR or phone menu systems. Or companies that have self-serve help forums instead of a customer service department. From there, we realized that consumers still needed more detailed help solving the most common problems, so we expanded to this set of guides, which grows every day. And if you spot any issues with our What do I do if my Xfinity TV or internet is out? guide, please let us know by sending us feedback. We want to be as helpful as possible. If you appreciated this guide, please share it with your favorite people. Our free information and tools is powered by you, the customer. The more people that use it, the better it gets.
After helping consumers for 10 years, we realized that you need an impartial, live person you can talk to about comparing the various TV, cable, Internet and phone plans in your area- somebody who can compare the best deals across telecom providers.
