What are Theft Alarm Notifications?

Theft Alarm Notification*19 is a feature within the Stolen Vehicle Assistance suite of services from OnStar, available on compatible vehicles enrolled in the Security or Guidance Plan, or as an add-on service. If your car alarm sounds, a Theft Alarm Notification will be sent to you, providing you early notification that may increase the chances of recovering your vehicle or personal property by working with local law enforcement and OnStar.

Is my vehicle equipped with Theft Alarm Notification?

Most model year 2014 and newer vehicles are compatible with Theft Alarm Notification. You can confirm if your vehicle is compatible by visiting your account on Owner Center or by speaking with an Advisor by pushing the blue OnStar button in your vehicle. You can also call 1.888.4ONSTAR.

How do I enroll in Theft Alarm Notification?

In order to receive Theft Alarm Notification, you will need to complete the following steps:

1. Confirm your vehicle is compatible with Theft Alarm Notification by visiting your account on Owner Center or by speaking with an Advisor by pushing the blue OnStar button in your vehicle. You can also call 1.888.4ONSTAR.

2. Ensure you are enrolled in an eligible OnStar plan. Theft Alarm Notification is available in the Security and Guidance Plans and as an add-on service.

3. Set up your notification preference (e.g., phone, text message, email) for receiving notifications on Owner Center or through an Advisor.

4. Every time you leave your vehicle, arm it by electronically locking your vehicle via the power door lock button or your vehicle key fob, or by using your vehicle's mobile app remote door lock feature.

How do I change my preferences?

To set your Theft Alarm Notification communication preferences, visit your account on Owner Center and log in to your account. You can set your Theft Alarm Notification preferences using the existing contact information on your account. You can change these preferences at any time on Owner Center or through an Advisor.

How do I choose who receives notifications?

U.S. Members can have multiple individuals receive notifications. All recipients must be listed on the account with the necessary contact information. To add drivers to your account, push your blue OnStar button or call 1.888.4ONSTAR to speak to an Advisor. You can remove some or all of your notification preferences via Owner Center or through an Advisor.

What do I do if I receive a Theft Alarm Notification?

If your vehicle has been stolen or tampered with, file a police report and let them know you have OnStar enabled. If your vehicle has been stolen, the authorities can work with OnStar to help locate your vehicle and, in some cases, use Remote Ignition Block or Stolen Vehicle Slowdown, which are other features within the Stolen Vehicle Assistance service.

What is Remote Ignition Block?

Once a vehicle has been reported stolen to law enforcement, OnStar can send a remote signal that blocks the engine from starting.

What is Stolen Vehicle Slowdown?

Once reported stolen to law enforcement, OnStar can send a signal to help authorities recover your vehicle and reduce high-speed pursuits. Once the police confirm that conditions are safe, an OnStar Advisor can send a signal that gradually slows the vehicle to an idle speed.

What do I do if the notification was a false alarm?

If your alarm was accidentally triggered and there is no problem with your vehicle, we’d appreciate it if you would contact 1.888.4ONSTAR and select menu option three to report the alarm as accidental.

My vehicle was stolen. What do I do now?

If your vehicle has been stolen, contact your local law enforcement to file a police report and let them know you have OnStar enabled. The authorities can work with OnStar to help locate your vehicle and, in some cases, use Remote Ignition Block or Stolen Vehicle Slowdown, which are other features within the Stolen Vehicle Assistance service. You should also contact 1.888.4ONSTAR and select menu option three to begin the Stolen Vehicle Assistance process. The OnStar Advisor will ask you for the stolen vehicle report number and confirm if law enforcement is involved.

What do I do if my vehicle has been damaged or has had property stolen from it?

Most insurance companies require a police report for vehicle damage or personal property theft. You should contact local law enforcement to file a report and then contact your insurance company. In addition, contact 1.888.4ONSTAR and select menu option three to report the incident.

What can trigger an alarm?

The theft-deterrent system in your vehicle may be triggered by the following:

  • Key learning (copy of key made)
  • Forced entry alarm (door, trunk, hood)
  • Tilt/inclination
  • Interior movement
  • Charging alarm (electric vehicles only)

What do I do if I’m not receiving notifications?

There are a few limitations that can prevent the Theft Alarm Notification system from sending an alert. If you are having problems, check these issues:

  • Whether a valid key was used to start the vehicle
  • If the vehicle was towed away and is not equipped with a tilt sensor
  • Whether the theft alarm system is damaged
  • Whether the vehicle was properly armed, meaning the doors were not electronically locked from either inside the vehicle, via the vehicle key fob or your vehicle's mobile app
  • Your vehicle may not be equipped with the more advanced theft sensors, like glass-breakage or interior movement. You can check to see what features are available on your vehicle by visiting your account on Owner Center or by speaking with an Advisor by pushing the blue OnStar button in your vehicle. You can also call 1.888.4ONSTAR
  • You do not currently have an active OnStar Security or Guidance Plan
  • You do not currently have a preference set to receive a Theft Alarm Notification

What do I do if I’m receiving notifications when the alarm isn’t sounding?

Some vehicles have a “key learning” theft trigger, which will not sound the vehicle alarm when activated. The “key learning” theft notification is triggered when someone has made a copy of a valid key. If you requested to have a duplicate key made, the duplication process will trigger a notification to you. If that’s not the case, you can call 1.888.4ONSTAR and select menu option three to speak to a Stolen Vehicle Advisor who can check to see what theft sensor was triggered for your notification.
