Need help with radio LOC
Hi all,
New to the group. Just picked up a 98 C5 and having "LOC" displayed on radio after doing a 12V battery reset. Below I have placed the procedure I have found all over the interwebs to unlock but it seems the phone number included in the instructions is no longer valid. Any advice on the new process would be greatly appreciated!
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 620529 then # (pound). You will be asked to enter your four or six digit code followed by * (star) [IF THE "620529" doesn't work, try 206053, 202107, 106010 or 202108.]
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.

Where did you buy the car? If from a dealer, make them contact the original owner for the code. If bought from the owner, contact that person for the code. If still no code, look for someone selling the radio in the for sale area. I suspect it will be much less then $160 being charged by the dealer.

Hey checked around. They said if what LWS posted doesn’t work your best bet is the Dealership. Unfortunately $160 is typical charge. :/ Please keep us posted , hope you find a solution asap.
