A dealer will have this code based on the Vin. How ever if you have the original owners manual it should be in it.

Unless somebody wrote the code down in your owners manual, you will have to take it to the dealer. They will push a series of buttons, get a code out of the radio, then call the factory to get the unlock code. I'm sure there is an associated fee involved.

remove the radio call in the model and serial number to the dealer, or take it down to them if it's really close, but bring your title too.
You then have an hour and a half job ahead of you, not work but you'll have to wait an hour and a half.
After you get the code, turn the key on Acc for 1.5 hrs and the radio will prompt for a 4 digit code. key it in and voila....tunes instead of YOU singing.

If it is available  then this place will definitely help...especially on these  older BMW radios

most likely you have inputed the code several times and it has completly locked up. The only way to unlocked it would be trying to leave the stereo on for about an hour so it can reset it self and then retry to put the code in

You will need to take your registration for the car and ID with you for proof of ownership with you to the dealership.

Take the headset to my BMW dealer and verify that you own this radio and then, they will look for the unlock code on their computers, of course after getting a specific serial # that’s placed on the back of the radio.

I had the same problem with a 97 transport. Here is a couple solution to your locked radio problem. This is assuming you have the ACDelco radio original to the vehicle. One way is to allow the vehicle to warm for an hour. After warming the vehicle press either the 1/2 or 3/4 or 5/6 buttons together. In two on the sequences, a three digit code will come up. Write these codes down. I called the original seller of the vehicle, (if known) or a GM dealer. Speak with the parts or service department. They do not have the 4 digit code to unlock the stereo, though they can make a call to ACDelco and get the code. The other way is to take it to a dealer and have them erase the code, which is approx. 30-50 dollar depending on the service station. Hope this helps.

1991-94 Nissan Maxima key less entry reprogramming procedure:

1. Enter the *original code found under the dashboard.
(*the code begins with the letter F and has 7 digits)

2. Close the doors and lock all of the doors,
enter the 7 digit code ( make sure you have your key in hand).

3. Once the code is entered correctly you will hear a long beep ♪ ♫.
While the beep ♪ ♫ is sounding ... ENTER your NEW 4 digit code, (you will then hear random beeps ♪ ♫)
Do not touch anything until the beeping ♪ ♫ stops.

4. To open the doors, the front windows and the trunk,
type: S(Clear) and the New 4 digit code and the door will open automatically.

5. IF by any chance you forget your new code. Just enter the original one and start all over.

After failing to enter the correct code in 3 successive tries, you must leave the key in the "ignition on" position with the radio on. This will allow you 3 more tries to reset the 5 digit code.
If you enter an erroneous digit, you must complete the 5 digit code, even though it is wrong. You have 2 more attempts to enter the correct code.
