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.

This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

what you need to do is pull the radio out and write down the serial number then call the dealer for the code. they may charge you 15-25 bucks but that will save you some money

are u the original owner of the car ?if so do you still have the books that came with the car? look for the delco radio book !there should be a card in there with a code and instructions! if not the only wasy is to go to the dealer or a radio repair shop to have it unlocked!

If the code is not written on the radio casing or inside the glove compartment, in/under the ashtray, behind the sun visor (or similar “hidden” place inside your car ) then the majority of HONDA codes may be available here
You will require the car VIN number and Radio serial Number
If they cannot provide your code then you will have to try your HONDA Main Dealer .....or a Decode Service who will plug in a laptop to read/recode the memory chip (EEPROM)
