Determining Factory Backup Unlocking Code For Secured Radio Assembly

It is inevitable that after activating the Delco Loc II feature with a six digit user code that the unit will lock when the battery voltage is interrupted and the user cannot recall the six digit user code previously used to activate (and needed to unlock) the Delco Loc II feature. When an owner had forgotten the six digit user code and wants the radio/CD player unlocked, the owner will have to take the vehicle to his local dealer or Delco radio repair center for assistance.

All integral radio/CD players with Delco Loc II contain a factory back-up code which can be accessed to unlock a unit when the user set code is not available. To access the factory back-up code refer to the appropriate Dealer Management bulletin for the complete procedure to access the factory back-up code.
