4 digit and 5 digit codes on 325i 1994
 

Having a problem with Radio code which is 5 digit but there is also a 4 digit code not on the radio but lower on the radio console,, I MESSED with that thinking it was RADIO, NOW CAR WONT START... how do you reset that 4 digit code its a 325i 1994

Now I'm getting a clock timer, starting at 15 minutes and counting down? I hope it doesn't self destruct at the end..

The radio code is five digits, but it is not written anywhere on the radio or in the car. That would defeat the purpose. You have to take the serial number off the radio to the dealer and have them look up the code if you don't have the card that came with the car.

If you key in the wrong code, you have to wait with the radio powered and turned on for it to time out before you can try the code again.

Nothing you do with the radio will keep the car from starting. There are two separate things going on.

I know about the radio.. its the 4 digit code down where the clock is what I'm wondering about?
