Theft-Deterrent Feature After Power Loss

HELP! went to start the 02 and the battery was dead. After getting it started everything work fine EXCEPT for the radio.

See pages 3-29 and 3-30 of the C5 owners manual, specifically "Unlocking the theft-deterrent feature after a power loss." Sounds like the theft-deterrent feature is activated/enabled on your car, and it engaged due to a power loss. The manual has about 9 steps you need to go thru if you know your "secret code." Otherwise, at the bottom of page 3-30 it says "If you lose or forget your code, contact your dealer." :confused If my theft-deterrent is active, I'm in trouble, cuz I don't remember or don't know my code. Hopefully, it was never activated. Can't remember anything being said about it.

If you don't have a manual let me know and I can type up the 9 steps. Else, you might be able to download the manual (or the parts you need) from the Chevrolet "My Chevy" section.

Hope that helps...Dave

Here is the "fix" for you:

The following procedure will give you a new code that you can use instead of your personal code. Using this new code, you can “unlock” your radio and then “re-lock” it with a new code if you wish. Prerequisites: The radio must be in LOC mode NOT in INOP mode. Let me explain. If you have activated the Theft-Deterrent feature of your radio and loose power, the radio goes into LOC (theftlock) mode. With the ignition on, you must use the MN and HR buttons to enter you personal code in order to unlock it (The instructions are on page 3-27 in your Y2K Owner’s manual). If you fail to enter the correct code eight (8) times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode (go for a long drive somewhere). Procedure: 01. Turn the ignition ON (The radio displays LOC) 02. Hold down the Radio Presets 2 and 3 buttons for six seconds 03. The radio display changes from LOC to a three-digit number. Write this number down. Don’t take forever, fifteen seconds max before the next step. 04. Press the AM/FM button 05. The radio display changes to another three-digit number. Write this number to the right of the first one. 06. You now have a six-digit number, the first three digits are from STEP 03 and the last three digits are form STEP 05 07. Call 1 800 537 5140 08. Press 1 then # (pound). You’ll hear “Invalid Code, try again” 09. Press 139010 then # (pound). You will be asked to enter your four or six digit code followed by * (start) 10. Enter the number from STEP 6 then * (star) 11. Listen to the four-digit number and write it down. It will be repeated twice 12. Turn the ignition ON (The radio displays LOC) 13. Use the MN and HR buttons to enter the code from STEP 11 14. Press the AM/FM button. The radio display changes to SEC Your radio is now “un-locked” and usable. The Theft-Deterrent feature is STILL active! If you want to disable it, use the instruction on page 3-27 in your Y2K Owner’s manual. Use the code from STEP 11 instead of your personal code. Note: This tip originated from LOTZAHP, Austin TX (credit must be given where credit is due). I verified it on an Y2K C5 with a locked radio - mine.

Wow...That's pretty elaborate.

I'm interested to hear if that works.
