I know it is possible to get a new code for a radio that is locked up. But where or how do I get the unlock code for my radio before it locks up? Thanks!

 

From the Tech Tip section

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.

 

I did this and it doesn't take as long as you might think. What stumped me at first were the MN and HR buttons .... They stand for minutes and hours (to set the clock) and they are tiny buttons located under the auto tone button.

 

My 98 c5 radio is locked I followed the insturctions here and got a 4 digit code from the ph number given however when I go to input it into my radio it only has 3 dashes and will not let me put in a 4 digit code. What is that about? any help

 

9 years, is that a record? I wish I had kept track;

 

and anyway you read it!!! SO what is your point? Ridicule?

 

You forgot to tell him to jump down turn around and pick a bale of cotton

 

Advice. Start a new thread and you'll get more relevant information. Lot of people would skip over a thread started in 06. I heard that the 800 number listed in 06 no longer works, but feel free to give it a try. Also feel free to skip over my post if you don't like the way it hurts your feelings.

 

Being new to the forum, at least he figured out that there is a lot of information out there using the search function.

Some owners have reported that the six digit code (139010) you enter may not work. There is a list of optional codes you can try in Step 9 of the above procedure. In the attached document, it is detailed on page 4. Give that a try and see if it helps. If not, best to just take it to the dealer and get them to unlock it. Of course, this assumes that the radio is in the LOC mode and not the INOP mode. Good luck, hope it works for you.
