Radio says LOC on My 1999 Oldsmobile Silhouette. Dead battery, after recharge radio locked out.I need a radio unlock code for my 1999 Oldsmobile Silhouette. This past winter my battery died during repair work being done. The tech never unlocked the code on my radio and gave my husband the runaround. I have been without my radio for 6 months and tempted to just buy a new one. Is there a generic code used that can unlock my radio?
Answer: First you must do this procedure.....Simultaneously press and hold the 2 and 3 push buttons for about 6 seconds until the first 3 digits of the display code appear. Write the numbers down.
Press the AM-FM button. The second 3 digits will display. Write the numbers down. Then i must call these numbers in to get a factory backup code. There is a fee that i must pay to get this code, so i will need to be reimbursed for that.
Then i can give you instructions on how to enter.
If the radio says INOP, then too many tries were made, and it is in level 2 theft. You will need to leave key on for 1 hr without touching radio before anything can be done. Be sure to have van running, or a battery charger on it, or the battery will go dead.
