A serial number is located on your radio that you can give to a Honda dealer who then can look up the code. (contact the service dept.) It's up to you if you want them to remove it and pay a fee or if you want to attempt on your own. I was able to remove the cover and get to the number myself. The serial number is how my code was looked up. Hope this helps!

Car stereo


There should be a display. OE radios tend to use the car's general purpose computer display.
If there is a code It is likely to be an OE product and the code and audio manual (and spare keys) should have been passed on by the previous owner. If such things are not with the car the resale price should be considerably lower reflecting the trouble and expense not having such things can cause subsequent owners.

If the previous owner cannot or will not help I suggest you contact your local VW dealer.

Radio won't work. reset battery and it works until you shut the car off, then won't come back on.


May be it needs complete reprogramming.

To reprogram the radio there is 4 digit code. That code has to be inserted, once these code is inserted, your car radio will get into its actual setting where you can set/select your radio setting.


Many a time's radio asks for the code after car battery is disconnected.

On some cases to retrieve the code its mentioned in manual or else car dealer is other option to get car radio code.

How to unlock radio from a2001 chey cavalier


see this technique and fix it. God bless you
Instructions
  1. With the Unlock Code
    • 1 Locate the anti-theft/unlock code. Most cars have a special anti-theft radio card that is included with the owners manual packet containing the unlock code and serial number. Some cars also have the code in the car manual or inside the glove compartment. You will need this code in order to unlock your car radio.
    • 2 Turn the car's ignition switch to the "on" position. This turns on your car's electrical system and powers up the radio. The word "CODE" will display on the screen. Note: depending on the manufacturer some radios will display either "ENTER" or "LOC" on the screen instead.


    • 3 Enter the anti-theft/unlock radio code. Press the "Tune" button on your stereo. It will change the screen from "CODE" to blank. Press the button to scroll through the available numbers. When you reach the correct number press the button once and hold it down for a few seconds. The number will appear on the display and you can now repeat the process to input the second number, third number etc., until all of the numbers are in. If you entered the code correctly the car stereo will unlock and instantly become functional. Depending on your car manufacturer, if you enter the code incorrectly you will not be able to re-enter it again from 1 to 24 hours.
    Without the Unlock Code
    • 4 Call your car manufacturer directly. Your car manufacturer's phone number is in your owner's manual. Ask to be connected to the support department. Tell them you need to reactivate you car stereo and you will be asked for proof of ownership. They will need your car's VIN number, the account number from your bill of sale and a form of personally identifiable information like your driver's license. You may need to fax this information. Once everything checks out the manufacturer will give you the code.
    • 5 Enter the code and unlock your stereo. Use the code you received from the manufacturer to unlock and and activate your car stereo.
    • 6 Go to a car dealership. Take your car to its manufacturer dealership to get the stereo unlocked. For example, if your car is a Honda go to a Honda dealership. Once you have proven that you are the owner of the car, the dealership will be able to retrieve the code from the manufacturer and activate the radio for you.

CD, Radio will not work, shows CODE on the screen


Yes this happens because the radio enters a security mode (anti theft) after you disconnect the battery terminals to it, I'm afraid you can not find that code on internet, you can either find it on your car's owner's manual or go to a Honda dealer ship and they'll provide you the security code for your car, not a big deal. Hope it helps and please rate the answer, as it helps me with my general ratings, thanks! P.S. comment if you need more advice

Honda car stereo


I won a 2004 Honda Civic.
I had a bad battery and my car would not start. I had someone jump start it and it now has a new battery. The car runs fine but the stereo will not play am/fm or CD's. Regardless of what I do I get an "Error E code"

Please help.
