    after trying to find out how to do this i found a free way and figured i would share what i found!!
    let me copy and past what i found because when i was looking every one wanted $6.99 all the way up to $50 from chevy!!!


    • The radio must be in LOC mode NOT in INOP mode.
    • Turn the ignition ON (The radio displays LOC).
    • Press and hold presets buttons 2 & 3 or 1 & 4 for approximately 10 seconds.
    • The radio display changes from LOC to a three-digit number.
    • Write this number down.
    • You will then have fifteen seconds max before the next step must be performed.
    • Press the AM/FM button.
    • The radio display changes to another three-digit number.
    • Write this number to the right of the first one.
    • You now have a six or four-digit number, the first three digits are from STEP 3 and the last three digits are from STEP 5.
    • If you have a four digit number, it will show all four digits at the same time.
    • Example 4523.

    if you have a rds radio the 1&2 of 3&4 presets wont work it has to be hooked up to a hand held computer at the dealer. it should say rds on the face of the radio near the display .


    if not you have to hold the pre-set buttons for a few seconds it had a situation that it wouldn't work unless the vehicle was running. maybe dumb luck i don't know.

    anyway if you can get the code write it down

    call 1800-537-5140 when the recording begins
    press 106010 then * it will ask for your code
    enter your code followed by *

    it will give you your unlock code.

    Should be able to access by pressing the minute button then 000 should appear.
    Press the minute again to make the last two digits to your code # then press the Hour button to make the first digits match your code.
    After you entered you code press AM-FM and if done right SEC or something should be displayed.

    This all has to be done with out more then 15 sec between steps.
    Also if you fail 8x entering the code, INOP will appear and you'll need to leave the key on for a hour to reset and try again.

    hope this will help someone:glasses:
