Hello,

So, enter a code varies depending which radio you have; however, looking at the different entry instructions, it seems that the preset station buttons are used to enter the code and the station increment button ">" accepts the code.

Hope this helps,
Bill

My battery went flat and I jump started my car (Holden VT) now my stereo is locked. Dose anybody know how to unlock it. It's a eurovox radio unit.


Samantha, You need the VIN and the radio serial number. Take those into a Holden dealer to get the radio code and programming instructions from the dealer. They may want a small fee for the #. Check the attached links,instruction and guides, Good luck

How to insert the code for the radio of my golf3 /1996



ENTERING SECURITY CODE

Most vehicles are equipped with Heidelberg V or VI radios that are equipped with a theft protection program. When the battery has been is disconnected or if the radio has been removed, the radio will lock-up electronically and cannot be operated until the security code is entered. On the Heidelberg V, if the proper code is not entered in six attempts, the radio will lock-up permanently and cannot be repaired. On the Heidelberg VI, two incorrect attempts will lock the radio for about 1 hour.
The Heidelberg V may have a code assigned at the factory or a personal code created by the owner. The Hiedelberg VI has a code assigned at the factory and entered by the dealer during pre-delivery inspection. New radios come with the code printed on a sticker but not entered into memory. All codes are 4 digits. To code the radio:
Heidelberg V

  1. Turn the radio ON . The radio should display the word SAF. DO NOT attempt to eject a cassette with the radio in this mode.
  2. Push the AM/FM and SCAN buttons at the same time and hold them until the display changes, then release them immediately. The number 1000 will appear for about 3 seconds, then the display will go blank. Release the buttons then.


NOTE If the buttons are held too long, the radio will interpret this as an attempt to enter an incorrect code.
  1. Use the first four station selector buttons to enter the code. The first digit of the code is always 1. Each time the other buttons are pushed, the number in that position will change.
  2. When the code appears correctly in the display, push the AM/FM and SCAN buttons at the same time. When the radio plays and displays a frequency, release the buttons.
  3. If the code was entered incorrectly three times, momentarily disconnect the battery and try again. If the code is entered incorrectly three more times, the radio cannot be coded and cannot be repaired.

  3. If the code was entered incorrectly two times, leave the radio ON for one hour and try again. This can be repeated as often as required.

SEC appears on the radio Lexus ES300


SEC stands for security, the radio is in theft lock you must enter the unique code security that came with the car when new to unlock the radio, this SEC is triggered whenever the radio losses power like a theft or a battery disconnect. If you don't have this unique code you must see the Lexus dealer, they can look it up in the factory information link, it goes by the serial number of the radio and the VIN or the car.

I switched my lights on to brights instead of automatic and I forgot to turn them back overnight and my battery died and needed to jump it, the next thing I knew my pioneer radio wouldn't work, I checked...


Your radio, when power went down/off it went into LOCK mode. You're going to need to enter security code to get on again. It's an anti theft radio. Hopefully you have code in glovebox or with owners manual. If not you need to contact Pioneer and they'll want radios' serial #

Volvo Car Radio Lock


There is a 4 digit security code that needs to be entered into the radio. Look in your owners manual, it may be written in the book or there may be a card in the booklet that has the code. If you find it, enter it once, if it doesn't work, stop, because entering the wrong code will lock up the radio. You will need to go to the dealer to get the code if you cannot find it.

How do i enter the radio code on my acura rsx


When you turn on the radio and it says code,you need to press the station presets.according to you code. If you try to enter the code too many times and it says error, then you need to disconnect the battery and let it sit for about 10 minutes for the radio to clear and then reconnect the battery, When the radio says code try again. If that still fails you may have to visit your dealer to have him look into the problem.
