Question about 1989 BMW 3 Series
There is a secret to entering the 5 numbers of the code on the radio of the BMW. I have had the correct number but am forgetting something special about entry because after 3 tries it locks you out until you have driven it for several hours. I am now at number 2 try. What am I doing wrong?
SOURCE: Lock code for radio cassette
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.

Take your radio out (Using an Allen wrench) there are 2 little doors on either side of your radio. Back out the recessed allen head screws till it stops and withdraw the radio out. Disconnect the radio wiring(no need to worry they only fit one way) take the radio to the dealer with your Reg. or title and ask the service advisor for the code. (they might try to charge you for the code. But just complain and say" that you have had many bmw and you've been comming to the dealer for parts for years now and it that how you treat me"!) that should get you the code (If you are a woman then wear something tight & Skimpy) same effect. put the radio back in and input the code...
You should be good to go.

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.
