    hi, I have the same problem. I have been tried three times and none of those were successed, now my radio at 7 safe status. does someone has code originally from holden zavira and let me know, then I may try that code as I hear from friend of mind usually the code pretty much similar (as long as it has not altered).





    thanks

- WHEN YOU KNOW WHAT YOUR RADIO CODE, TRY THIS: I JUST TRIED THIS ON MY 520 IN A HOLDEN VECTRA (1999) AND IT WORKS:
- HOLD DOWN THE 'AS' BUTTON UNTIL YOU HEAR A BEEP, THEN YOU GET THE FOLLOWING DISPLAY:
10 - - - -
- PRESS BUTTON NUMBER 1 UNTIL YOU GET THE FIRST DIGIT IN YOUR CODE
- PRESS BUTTON NUMBER 2 UNTIL YOU GET THE SECOND DIGIT IN YOUR CODE
- PRESS BUTTON NUMBER 3 UNTIL YOU GET THE THIRD DIGIT IN YOUR CODE
- PRESS BUTTON NUMBER 4 UNTIL YOU GET THE FOURTH DIGIT IN YOUR CODE
- HOLD DOWN THE 'AS' BUTTON UNTIL THE STEREO TURNS ON.

Vectra 1999,
wot u have to do is........
turn on the ignition turn the radio off, press down "AS" and hold and then turn on the radio! and it will come up the usual 7 SAFE
then keep "AS" pressed for another 2-3 seconds then let go. Then you have to LEAVE!!! key in ignition its ok to drive while doing this because i did but dont turn ignition off or take the key out or ull have to do it agen! i got told that it takes around 1hour to reset itself but myn took around10minutes, once it has reset the code option will appear.
DO NOT type in 1234 as that is not the code. Every radio etc has there own code so who ever braught the car brand new must have the codes, i found the codes on the back of my service booklet where the man i braught it from must have wrote them down to remember.
the reason its staying on 7 SAFE is because you have locked the radio because you have had more than 3 attempts so wot i have just told you to do that will unlock it but you must have the right number!
iive gvot a problem where i have unlocked my radio but now the cd player is saying SAFE when i try to use it so if any1 knows wot to do please tell me.
hope i helped any1 out. i have a vauxhall astra so hopefully ur vectra is more or less the same

Hi i have a problem with my customer i already selled him a kenwood car stereo the model num : KDC-W5031 and it appears waiting on the screen and also i dont have the security code


I had a problem as well with my KDC-MP6025 after I changed my car's battery. I called Kenwood four times asking about why my security code wouldn't take, and on the fourth call the tech said some random 2004 models (definately the MP6025, and probably it's sister receivers the KDC-X678 and the MP625) the decks firmware subtracts one from the 3rd digit if the sequence, i.e., if you set it for code 1234, you'd have to enter 1224. Since I sent Kenwood my product registration, it would have been nice for them to tell me this. I would have been BS if I had found out after if I had kept my $60 appointment to get the code cracked at the authorized repair place Kenwood recommended.

I have the kenwood kdc mp228 cant get in it. a friend says i need the lockout code to get in it. help me plzzz


try using the code "kcar" on your remote press the numbers that correspond to the letters . This code is used for most basic kenwood, make sure you have valid remote because sometimes the stereos do not allow you input manually from the face plate

Lost radio codes


Not familar with your car but I had same problem many years ago with a Vauxhall Astra and did same as you, disconnected battery and re-connected, radio didn't work - but my display kept flashing for security code to be re-input, which I didn't have.
Yours could be the same if radio not worked since disconnection - solution: if you dont have code & not in any documentation you got with car, then the radio will need to be re-coded by a dealer (expensive) or enquire with local car spares shops - they normally know a cheaper source. Mine cost about £18 (5 years ago) to get re-coded & I had to remove & reinstall myself.

Do you have a code that you had to enter to unlock the stereo? Have you tried to reset the stereo? Look in your owner's manual and look for a "RESET" button. If you don't have the manual, you can download one from pioneerelectronics.com.. Hope this helps...

Hey, if you have the title to the car, just get the VIN and call the company.
