When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

In a situation that the security feature has been enabled on an OnStar Personal Calling capable vehicle, the OnStar Center is able to unlock a vehicle in this condition.

The procedure to do so is as follows:

1. The owner/account manager must make a call to the OnStar Center.
2. The caller must inform the OnStar advisor of the situation with the security feature being enabled.
3. The OnStar advisor will transfer the individual to Customer Care.
4. The Care advisor will verify all account information, including the original PIN selected by the owner/account manager when the account was initially set up.
5. Once this is done, an outbound call will be made to the vehicle by the advisor which will unlock the security feature.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
