    Your solution seemed illogical but did work. I had to see the service manager at the local dealership for another problem. He too gave me the same solution. I then came home and use the solution provide by you and the dealer ship. Results to get back to the system asking for code took less than 5 minutes. However, after entering the code provided by Mercedes the first number of the code began flashing and I proceeded to enter the solution recommended by FIXYA with no results. But I will rate the overall professionalism provided to me as NUMBER ONE. Thank You.

You must leave the key in the ignition switch for 1-2 hours in the on position with the radio on to reset. then you can reenter the correct code- if you tried to enter the wrong code 3 times the radio's antitheft system will have engaged and the only to reset it would be to go to a mercedes dealer to have them use their computer to reset the radio- there are no other options

I don't have a solution although, I do need to know the code for resetting my radio in a 95 Mercedes E320. Changed the alternator and battery out. There hasn't ever been a manual so I could use someone's help without having to pay for the code.

Astra coded radio cant enter code??


I would suggest that your radio got a voltage surge when your battery was recently removed and re-connected. I would either:

1) Remove radio (if you have the special tool), unplug and re-connect harness, or

2) Pull the fuse in the fuse box for the radio (may be two), or

3) Disconnect the negative post to the battery, wait 30 seconds and re-apply (very quickly).

If the display does not reappear, I'm afraid the radio is damaged. Let me know.

How to reset security code for a 1997 mercedes benz c230


Check the manual for the security code for your vehicle. I'm pretty sure it's a 5 digit code. If you locate it, enter the code into your stereo. You may have to take it to a Mercedes dealer if you cannot find it. If you do have to take it to the dealer, pull the radio out and get the serial number from the side of the radio, the service tech will charge you big bucks if you make him do it. I hope this helps =)

I have a kenwood car radio /cd my battery recently went and was replaced and the radio is now asking for a 4 digit code which i dont have .I have amanual but nothing is written in the back what can i do ?


You can enter a 4-digit security code which must be used when the unit is removed from the vehicle, or the constant power source is disconnected from the unit. When constant power is restored to the unit, the security code must be entered before the unit becomes operational.
If the code is lost or forgotten I am afraid the unit has to be re-coded by a Kenwood dealer.
Good luck with it.

KENWOOD RADIO CODES


Common Kenwood Security Codes
Many Kenwood radios are configured with the same security codes:

KCAR - This seems to be a "backdoor" to some Kenwood models.
3051 - This is the security code which is printed in the manual of many Kenwood models.
1234 - This is a security code commonly chosen by Kenwood owners.
Entering Your Kenwood Security Code
If the car battery fails or is disconnected, the Kenwood will ask for the security code.

The procedure to enter your security code differs on various models of Kenwood car stereos. Here are three of the more common procedures:

Type 1
During the code request mode, while holding the DISP key depressed, press and hold the Volume UP or DOWN key for 3 seconds until the "..." display disappears.
Enter the security code using your Kenwood remote.
Type 2
Press the "Auto" button and "Track up" on the face of radio at the same time until the four dash lines disappear.
Enter the security code using your Kenwood remote.
Type 3: Model# DPX-4020 and DPX-4030
Press and hold the 1 then the 6 preset keys until the display shows the letter 'C'.
Enter the security code using your Kenwood remote.
Entering Letters on your Kenwood Remote
To enter a letter using your Kenwood remote, press a button once for the first letter, twice for the second letter, and three times for the third letter -- then press the Track Up or Next Track key to send the letter.

To send the letter 'A', press the 2 key once and then press the Track Up key. To send the letter 'B', press the 2 key twice and then press the Track up key.

Finally, when you are done entering all of the letters, press and hold the Track Up button for 3 seconds.

The key sequence to enter the security code KCAR is:

5
5
Track Up
2
2
2
Track Up
2
Track Up
7
7
Track Up
Your Kenwood should then enter tuner mode.

A Security Code Bug in some Kenwoods
There is a reported bug in the security code handling of some Kenwood stereos. In models with thie bug, the security code is stored incorrectly. The workaround is to enter the wrong security code.

In models with this bug, you have to decrement the third character of the security code by one. If your security code was 1111, you would enter your security code as 1101. If your security code was 9999, you would enter 9989.

Car radio pin code


Hi pat... bad news I'm afraid. You need to get the code from Eurovox. There is a way to change/defeat the code, but it involves having the thing apart on the bench and actually fitting a new memory chip to the radio that does not have a code. I used to do this if someone left a unit for repair and we were not left the code. I have cut and pasted the FAQ from Eurovox's site for you, Click the link to their code request form. There are also instructions on how to enter the code

And as always, the bastards charge for the info. Sorry I couldnt actually give you a code. I used to have charge $60 to recode a radio back in the day by rechipping it.


Why is my radio not working after the battery was disconnected/replaced?
The radio requires a security code to be entered. (also known as PIN number). A security code is either 4 or 6 numbers long for most of Eurovox Units.

How can I obtain my security code?
Download the Security Code Request form located in the Downloads section. Fill it out and send it in via fax or email with proof and payment. The serial number & model number of the piece of Eurovox equipment is essential. A new security code card will then be mailed to you and your details will be registered in our database.

Why does Eurovox charge for supplying a security code?
Security and administrative reasons. We enter your details in our database so if you lose it again you only have to identify yourself and give the serial number and we will give you the security code again, we also send you a new code card.

How do I enter my security code to my Eurovox radio/cassette/CD Unit?
Refer to the owner's manual of your equipment. Turn ignition key to 'Accessories' & a number '1' or code '1' or similar will appear. Press corresponding preset buttons as you read you security code. If you have a 6 digit security code, the display will count the preset buttons pressed. i.e. display will show '1' the '2' then '3' & so on up to '6' regardless of which number is pressed. If the security code is correct, the radio will turn on. If the security code is incorrect, the display will show '2' or 'code 2' or similar. After 3 incorrect attempts, the radio will go into 'lockout mode'.

Why has my radio got horizontal lines on the display & is not responding to any buttons?
The radio has had 3 incorrect security codes entered & is now in lockout mode. For recent model radio's leave 1 hour (some radio's require ignition key to be on accessories). For older model radio's, remove power to radio by either unplugging radio or disconnecting the negative lead on the battery for 1 hour.

My radio will not accept my security code?
(1) This radio may have been replaced and now requires a different security code
(2)The security code you have been supplied is wrong.
(3)This radio has an internal fault. To check if radio works there is a temporary test code '1111' or '111111' can be used for most of Eurovox Radio. This only lasts for approx 3 minutes.

How do I enter security code to my overhead DVD/Screen combo unit?
Using the <<or>> buttons on the overhead console, scroll up or down to select the first number. Once the correct number is shown, press the ENT button. Repeat this procedure to enter the 4 digit code. As each digit is entered, it will be shown on the display.

Why does "Code Input Error" appears on my overhead DVD/Screen Combo Unit?
If incorrect codes are entered for more than 3 times, your Eurovox overhead DVD/Screen unit will show "Code Input Error" on the display.
Leave car key in the car and turn it to Accessories for approximated 1 hour, the overhead DVD/Screen unit will reset itself and shows"Security Input 1***" on the display.


Good luck... a FixYa rating would be great for my attention to your problem. Cheers mate

regards
Graeme

1998 Mercedes ML320 Radio code instructions


does your radio ask for the code when you turn on the ignition key. If you see _ _ _ _ or **** you should enter the code using the pre set numbers for your radio, ie, first code should be entered using the first pre set key on the radio ( number one ).
Followed by the second code number being entered using the second pre set button and so on until all of the code is entered.
After entering the full code the radio should accept, if not enter code again and press the next pre set key following, ie, if the code is 4 digits, press the fifth.
Hope this works.
If all this fails most garages will set the security code for you for a small charge. Make sure you take proof of car ownership otherwise they will normally refuse to reset the code. This is to foil theft.
