BMW 1990 750IL RADIO LOCKED - 750L BMW Cars & Trucks

Pull radio out and get the right code from the dealer.

If you do not have the book for the radio, I believe there is a trick to entering the code. Its not just using the numbers. I think you have to hold another button down while entering the code or use the station up down button to enter the code. Try hitting all the buttons one at a time and see if that enters anything on the desplay.

BMW radios have a small tool needed to pull radio. Stop by any BMW dealer, service advisor can do it for you. (I used to work for BMW)

Contact your local BMW dealer, they would be able to tell you the code for your radio.

sometimes, a good owner, writes the code in the service book so that people like us can just reset it...
it will be cheaper to replace the radio fitted for a new unit.you do not have to replace it witha bmw one (mostly blaupunkt/bluespot

You must remove the radio (unscrew the two security screws under the small flaps at the left and right sides of the radio face), get the radio serial number from th etag on the radio, then go to a BMW dealer, who can look up the security code.

The two screws require a special tool for removal. you can get it at Bavarian Autosport:

Just make sure your radio is turned off before removing the battery. If the radio is on and the battery is removed and replaced, the radio may get locked out. This will prompt you to enter and reset code to your radio to have it work again. Good luck and after you battery has been replaced, just reset the radio stations setting and time. 

If the radio is displaying code wait, or wait, then the ignition and radio must remain on for 1hour. I would contact a dealer within the USA and provide them with your radio serial number. The serial number can be displayed in the radio by pressing and holding down the "M" button while turning on the ignition.

Simple to fix!

Go to a dealer of that car (eg. Ford, Holden, BMW etc.)

They will fix you up.
There is nothing I can tell you right here.

hello . ok this happends after you try 3 times an incorrect radio code on the radio then you have to let the radio on for 60 min and the lock display will turn to code again if this happends constanly then the radio protection is bad and you need a new radio or you may take the radio to a radio fix place for them to take the protection part out
