Imagine your child or dog locked inside your car while you are standing helplessly outside. That scenario can happen more easily than you might imagine. A child playing with the door locks or a key fob remote can lock the doors in the blink of an eye. An excited dog pawing at the windows and doors can push down a door lock before you know it. The OnStar vehicle assistance system can save you time, money and aggravation when you accidentally lock your keys in the car by sending a remote signal to your car that will unlock the doors.

Step 1

Call OnStar directly using a cell phone or landline at 1-888-4-ONSTAR (1-888-466-7827.)

Step 2

Identify yourself and your vehicle to the OnStar advisor. The OnStar advisor will ask you security questions to verify your account information before unlocking the car.

Step 3

Stay on the line with the OnStar advisor until your vehicle doors unlock.
