SOURCE: unlock antitheft code for 2004 chevy impala
Radios in the 2004 Impalas are tied to the vehicle's VIN through the computer, so it may be somewhat difficult to get the code. However, the following steps should work:
1. Press and hold the buttons for presets 1 & 4 (may be 2 & 3). The word "SEC" should show.
2. Press the "MIN" button. "000" should be displayed.
3. Press the "MIN" button again to have the second two numbers appear. Record these numbers.
4. Press the "HR" button for the first two numbers to appear. Record these numbers. -- Note: Your number sequence should be the numbers from the "HR" button followed by the numbers from the "MIN" button.
5. Call 1-800-537-5140. This will get you to the GM unlock code automated line. Ignore the prompt and enter "202108#". Next enter your code (remember, HR then MIN) followed by the * key. For example, 1234*. A 3 or 4 digit code will be given to you. If you get a code such as 0532, drop the zero when entering it into your radio.
6. Enter the code into the radio IAW the applicable manual.

Here is what you do ;
1. Press and hold the presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write them down.
2. After doing step 1 and writing down the code, immediately press
the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
those down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, you will have to start over).
3. Call this number, it's a prerecorded message, so don't worry about
having to talk to anyone...1-800-537-5140. The voice will ask if
you're
calling for Chevy, Pontiac, Cadillac, etc... When you here him tell
you
to press "1" for Chevrolet. They will ask
you
for the 6 digit code that you've written down. Enter that and press
the
* key. They will give you a code, and the option to get additional
4
digit codes, but 1 should be sufficient.
4. Follow the procedure in your owners manual for unlocking the
radio with your new code, press the hour set button on your radio
until
you get the first two numbers of the code, then press the minute set
button until you've entered the last two numbers. Immediately press
the
AM/FM button once the correct code is entered and the code SEC or
secured will be displayed on the display screen. Now, just turn the
radio on, and you are finished.
There is another step you can take to remove all codes from the
radio and start from scratch by entering your own personalized 4 digit
code so that you don't get locked out again. Just repeat step four
and
you should get a display screen that reads ---meaning the code is
out, and you can program your own code. Once you
receive
the 4 digit code from the recorded message, store it , because you can use that same code again.
Please remember to rate this fix.
