    The manual has no instructions for entering a code, its says radio will not work in another vehicle because of antifheft mechanism. there does not seem to be any instructions to input the code, it says to return to dealer. Do you still think it will work in anohter vehicle?

  • slawler2 May 31, 2008

    I tried the steps and cant even get past step one. On the radio display it say "LOCKED" and nothing I do changes it. Step one never changed the display to SEC. I tried it with the car on and off with no results.



    Any recommendation?



    Thanks, Sid

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.

    IAW = In Accordance With; Check the original manual for the radio for exact instructions on entering the code into the radio (they tend to vary).

You need a tech 2 scanner or equivalent tool to register the radio with the body control module. The radio looks for an ID # and if you have changed it it will lock. These scanners are around $2000.00 and therefor your best bet is the dealer or a competent service center. Dealer charges around $115.00. Good hunting.

I can't imagine any reason it wouldn't work in another vehicle. If the manual suggests to return the radio to the dealer, I would assume there is some sort of special equipment needed to clear it to function again.

What's a good after market radio for a 2005 impala


there are 100's of replacement radios for vehicles, what you need to keep in mind is,,, if your factory radio has the vehicle info on the radio screen, its connected to the computer and all that goes along with it, I have an 02 Malibu, and had a new radio installed, But they had to route wiring to the trunk, ( thats where they put the factory radio and wired it in ) so that all my factory functions still worked, I was a little displeased with Chevy for having this attached to a radio, and since the CD player stopped working in the original, I was able to purchase a new radio, amp , and have it and the old one installed , rewired, and it still cost me less than Chevy wanted for a replacement of the old radio, Just due to the CD not working, so be sure and check around when looking for a replacement,

The motors inside the players tend to burn out. You will have to remove player, remove top cover and cradle of the player, and remove your cd. Than either have new motor put in your player or purchase a new player mabey from ebay or equivelant.

The only thing that is left for you to do is to remove the stereo and then disassemble it and remove it yourself. A little daunting but needs to be done. Sounds like it went in wrong and then became jammed

2005 chevy trailblazer cd player won't eject cd


I have a 06 Z71 and it did the same thing so more than likely your just going to have to buy a new cd player. I would recommend going with an aftermarket cd player because you probably going to spend just as much on another stock unit.

2004 Chevy Trailblazer radio and CD player works, but no sound


if you have installed a new cd player in there then the propblem could be that your speaker wires and either touching each other or grounding them selfs out.. pull of the cd player and check to make sure all the speaker wires are covered properly and no bare wires are exposed.. if you still have a factory cd player in it then you will probably need to take it to a dealership to have it checked out..

2005 chevy impala ignition


on some GM cars you couldn't just replace the radio with an after market, because the radio is also part of the computer, controls the theft system and the door locks and much more, you have to buy an extra adapter that bypasses the old module, otherwise it will lock the car down, you should try to put the old unit back in and if the car starts up like it should, if it does you need to go to a larger radio shop and ask for the bypass module for the radio i think its like 60 or 70 dollars
