my mechanic changed my battery, which would normally leave all of my preset stations messed up, but when i turned the car on, there was no sound at all. i've tried switching the power button on, but to no avail. i think that this seems strange, as it was working fine before, and i've never turned the radio off. how do i fix this?2000 chevy malibu-battery replaced and now i can't turn on the radio?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 in your Owner’s manual. Use the code from STEP 11 instead of your personal code.2000 chevy malibu-battery replaced and now i can't turn on the radio?Check to see if the radio is connected to the battery and receiving power.2000 chevy malibu-battery replaced and now i can't turn on the radio?Its probably the security system, take it to the dealer to be deactivated, they will charge you though.2000 chevy malibu-battery replaced and now i can't turn on the radio?You'll need to get a code from the dealer, this system is to prevent theft.
If the power to the radio is disconnected it won't work again until you enter the code.
To prevent it happening in the future attach a wire to a battery and hook it up to your power leads or through the cigaratte lighter.
The code might be in your owner's manual or your service book.2000 chevy malibu-battery replaced and now i can't turn on the radio?try fuse/power,
