If the radio is locked up due to inputting the wrong sequence for the radio code it will say "wait" on the display. If this is the case then you need to leave the ignition on along with the radio in order for it to reset. This could take up to 24hrs. You can contact the dealer and give them the vin for the vehicle and ask for a VMI printout for the radio code. Some of the C-class 203 chassis didn't need a radio code.

Radio displays LOC


Your radio is in lock mode. You need to look in your manual, and find your radio code, and the procedure to put it in.
You may have to call a dealership to get the code, or even go as far as taking the radio out. Sometimes they supply a card in the vehicle with the code, some are in the manual, some are on the back of the radio itself, and some are a dealer only thing where they plug your radio in to their equipment to unlock it.

I have a 1999 cabrio changed the battery now radio is asking for code I do not have the code what is my solution is there a default code i can try


Probably depends on the year/model of the VW. For a 1999 through 2002 Cabrio, you would need to do this: obtain the unlock code that was shipped with the vehicle. If you don't have the unlock code, your local dealership can pull the radio and look up the code with the serial number. Once you have the unlock code, then turn on the radio. You should see SAFE displayed. After about 3 secs, "0001" should appear. Use the station preset buttons 1 through 4. Preset 1 changes the first digit of the code, and preset 2 changes the second digit, etc. Enter all 4 digits of the code. After code is entered, press right side of "Seek" button for about 2 seconds, until an audible signal is heard. If you hose up and get the wrong code...will go back to SAFE displayed. You will get another chance to enter the code. After 2 failed attempts, you have to wait 1 hour again for it to unlock. So carefully enter the correct code the first time.
Volkswagen uses the radio lock feature to prevent unauthorized users of your audio system and will not allow your radio to operate without the proper unlock code.
Volkswagen began using the anti theft feature around 1990 and is still in use in most Volkswagen vehicles today!
Step 1 - Retrieve radio serial#
Your vehicle requires that you remove the radio from the vehicle in order to retrieve your radio's serial number.
Number will start with vwz.Must be a 14 digit number.You must include all numbers and letters included in the radio serial#, including "vwz". Radio serial# Found on chassis of vehicles radio. You must remove the radio from the vehicle in order to retrieve the radio serial number. This number may be stamped in the metal, on side of radio.

Step 2 - Retrieve vehicle V.I.N #Vehicle identification number.Usually found at the bottom of drivers side window.
Step 3 - Purchase code at

http://www.radio-code.com


  • You will receive your radio unlock code, via email.

  • Approximate code retrieval time is 30 minutes to 24 hours.

To do it yourself you will need to have the radio removal keys to unlock the radio compartment .
look at this site and you will have an idea :

My radio is locked i just need the code for a monte carlo 97 GM delco radio


If the code is not at the back of your manual, try 0000 and if the radio locked it self from taking any more codes. Just disconnect the battery and that will reset the radio so you can re-enter the code. If 0000 did not work then log on to Radio-code.com, you can get your cod there for like $12.00 which is cheaper then the dealer and you get to know the codes as most dealer will just unlock the radio. Good luck and hope this helps, keep me posted if you have any more question.

Radio locked on my 98 grand prix need unlock code


If your lucky the dealer may still have it or the code may be written down at the back pages of your manual. The other place where you can get the code would be www.radio-code.com. before you try any of that, try 0000 to unlock your radio. Good luck and hope this helps.

Radio Unlock Code


if you bought the car new then there should be writen in the manual the code for the theft lock system on the radio. if pre-owned then it might ,might not be in there. or if you dont have one at all. go to your nearest GM dealer and have them fix it by finding the code. make sure to have them write it down for you incase this happens again.
