    I just fixed the very same issue.

    Turn your radio on with the key in the ignition running only on battery power. Keep on for 30 min to an hour. This should reset and re ask you to enter the security code.



    Wahla it worker for me

    or another suggestion is remove the power going to the radio for 5 mins, you can do this by removing the fuse in the fuse panel for 5 mins, put fuse back in, then enter code - if that doesn't work then you have to remove the negative battery cable for 5 mins, then reconnect neg cable back to battery, then enter code - the key to it is removing power to the radio - the last resort is to remove radio from the dash and unpluging the elec connector from back of radio for 5 mins - the factory "code" should be on a sticker stuck to the radio, you should be able to find it when you remove the radio from the dash.

I have the unlock code for my 99 saturn sl2 but i need the radio layout


Hello, you will need to enter your radio unlock code using these instructions.


  1. Press SEEK DOWN, SEEK UP, TUNE DOWN, or TUNE UP. The radio display should show 0000.
  2. PRESS SEEK DOWN to set the first digit.
  3. Press SEEK UP to set the second digit.
  4. Press TUNE DOWN to set the third digit.
  5. Press TUNE UP to set the fourth digit.
  6. If the code was entered correctly, the radio will display SEC (SECURE). The theft deterrent system for the radio is now active and normal operation may be resumed. If the code was entered incorrectly, the radio will display Err for 5 seconds and the LOC (LOCKED) will be displayed again. If LOC is displayed, repeat 1-6.
  7. If the correct code is not entered in 8 attempts, follow the next steps:
  8. 7.1. Turn ignition to ACC position. 7.2. Turn radio power switch OFF. 7.3. Wait one hour before repeating steps 1 through 7. If attempts to unlock the system are made before the one hour period is up, the radio will display INOP (INOPERATIVE). Continue to wait. If the ignition is not in the ACC position, power will never reset internally to allow itself to be unlocked. 7.4. After one hour, repeat steps 1-7.

1994 900 s radio code


If the code is entered incorrectly 3 times then you have to wait an hour, with the radio turned on, you will then get 1 chance to enter the correct code. Get it wrong and you have to wait another hour before you can try again.
Check with the dealership that you have the correct code. They will be able to tell you if you give them the VIN.

AR82.60-P-7502-01A Coding Radio
(MODEL all with CODE (750) Radio Becker Europa 2000 with CODE (751) Radio Becker Grand Prix 2000 with RDS)

  1. If the radio is disconnected from the power supply, it is not operational when re-connected. After switching on the ignition and the radio, the readout CODE appears in the display.
  2. The code number for the radio is advised to you on the enclosed CODE CARD.
  3. To enter the first digit of the code number, you have to continue pressing station button 1 until the correct digit appears in the display. Adopt the same procedure for the second, third and fourth digits.
  4. Once you have entered the correct code number with the station buttons 1, 2, 3, 4 and confirmed the entry with the SEEK button (press down), the readout CODE disappears. The radio can now be operated.
  5. If you enter a wrong code three times, you must wait 15 minutes before making a new entry. In addition, if 9 incorrect entries are made, the radio will then not operate for 24 hours. During this time the radio and the ignition (terminal 15) must remain switched on.
AR82.60-P-7502-01B Coding Radio
(MODEL all with CODE (353) Audio 30 APS with CODE (510a) Radio MB Exquisit with traffic news decoder, with RDS (Becker) with CODE (512a) Radio MB Special with traffic news decoder, with RDS.)

  1. If the radio is disconnected from the power supply, it cannot be operated by simply reconnecting. After switching on the ignition and the radio the word "CODE" appears in the display on the radio.
  2. The code number for the radio is given on the enclosed CODE CARD.
  3. Enter the code number with the station button, e.g. number 1, station button 1. After entering the first number the word "CODE" disappears and the number entered appears followed by 4 dashes. The next character to be entered flashes. After entering all five numbers, the first character starts flashing again. In this state the code number can be written over as frequently as desired. A correction can be made only by entering the complete code number again.
  4. Confirm code number: Press TUNE, AUTO/SEEK or SC button. The radio automatically switches on and indicates the radio station or frequency stored with station button 1.
  5. If an incorrect code number is entered and confirmed, the word "CODE" appears again on the display. If an incorrect code is entered three times the word "WAIT" appears on the display and the radio locks up for approx. 10 min. If the code is entered incorrectly three times again the radio locks up again for 10 min. Three more incorrect entries (a total of 9 incorrect attempts) increase the lock-up time to 60 min. Another three incorrect entries lock up the radio for another 60 min. The waiting time runs only when the radio is switched on.

How to reset the raido


Hello,

There is a trick to the procedure. You have to turn the key to position 1 or the first stop on the ignition. Turn on the radio and wait between 2.0 to 3.0 hours for the radio to reset and ask for the code. From the owners manual. My 97 takes between 2:25 and 2.5 hours to reset. Every radio is different.

To enter the code:

After installation or when the set has been disconnected from power, the set displays "codE" when it is switched on.
Enter the 4-digit code using the preset buttons. If the correct code is entered, "on" is displayed and the set is ready to use.
If you enter an incorrect code you must enter the correct code again from the beginning.

Incorrect code

If an incorrect code has been entered "rPt" is displayed. Enter the correct code.
After three unsuccessful coding attempts the set will lock and remain locked for two hours.
"OFF" is displayed.

During this waiting period:

the battery must be connected
the ignition key must be turned to position I
the unit must be turned on
Make sure the headlights are turned off to help prevent battery drain (please refer to page 2:6 for information on turning the headlights off). Enter the code again once this time has elapsed.

Goodluck!

Problem with entering anti-theft radio code for Honda Fit: The radio screen says: "Enter Code:" I enter the confirmed correct code, but when doing so when the actual code (all numbers) turn into letters or...


when you use the "preset keys" (the keys on the radio with numbers on them) to enter the code, each time you press a code number, a letter appears [c, o, d, e]. once the word is spelled out, from entering the correct 5 digits, the radio is reset, ready to go.

BUT if you miss a number, enter a wrong number, whatever, each number pressed, still makes a letter appear from the word "code". once the word is spelled out, by entering ANY 5 numbers, if ANY of the 5 is wrong, the radio displays a message "Error" and then a number 1 thru 10.

When you see the word "Error..."

the next preset button you push, starts the whole thing over again. The radio says "Enter code". That is when you enter the 1st of the 5 digits, the letter C appears, enter the next digit, the letter O appears, enter the next digit, the letter D appears, enter the last digit, the letter E apperas, the radio is reset, ready to go, if you got the 5 correct numbers entered.

you have 10 chances to enter the right 5 digit code. Each wrong try of 5 digits yeilds a display of "Error 1", "Error 2", "Error 3", etc 'till you get to 10 incorrect tries of 5 digits each.

If you dont get it right in 10 tries, you have to leave the radio "on" for an hour, then it will let you start the 10 tries over again.

Good luck!
