How to unlock Factory deck?

[LEWETHETIGER73]

Does anyone know how to unlock a factory radio from one car that was put into another car? It is all hooked up but the screen says locked. I just need the sequence to unlock it. Any help would be great.

General motors Delco were assuming?

if it is a GM radio...here


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 Owner’s manual. Use the code from STEP 11 instead of your personal code.

IIRC...that process only works up to a certain year. I'm not positive though.

yeah im not sure either but its worth a shot. If they never set a code you could always try the default code which is 0000



EDIT: Just found that this only works up until the year 2000. After that, GM encoded the VIN into the radio so it knows that it is in the right vehicle. If this is the case, you have to take it to the dealer and have it reset.
