1995 325i - Cannot exit passive mode

[neikoh]

I don't know how I did it, but the front doors only lock/unlock with the key! I cannot open the rear doors because they wont unlock via the unlock switch. I had to pull the manual release for the fuel door just to put gas in! What can I do? The manual says something about entering a code into the radio...however, I don't know the code to the alarm. PLEASE HELP!
