Question about 1994 BMW 3 Series
My battery had to be recharged on my 1994, BMW 525I... My anti-theft system and radio are not working now as a result, but worked fine before the battery was recharged... There is a CODE msg in the display... I read the manual & tried entering my anti-theft 6 digit code myself a few times (to make sure) but it didn't work... I don't know where the radio code is... How do I reset the codes for the anti-theft system & radio for my car?? ... Can you please advise me as to what I should do or help me?? ... Thanks in advance for your guidance with this ''code'' problem!
You are miss reading the code light, the codes start with a 12 and then the number. to bring them up you need to turn on the ign. press the fuel peddle to the floor 5 times quickly, the light will stay on for 5 sec. then out then on for 2.5, then off for 2.5, your codes will come next if any, there will be four set's of blinks, first should be a 1 then usually 2 bliks then a set of 1 to 8 blinks then and then a set of 1 to 8 blinks, this will give you your code, this will repeat with the next code if there is one. the codes will be 12xx, 1444 or 1000.

When you take the battery cables loose from an anti-theft system, You would place a nine volt (9V) battery across the positive and negative cables to hold the memory chip in the systems. This allows you to remove the battery for a period of time longer than a few minutes. The system (anti-theft) is designed with a couple of capacitors in the system that hold the charge for a few minutes to allow changing of the battery. If the battery is removed for much longer than 30 minutes then the capacitors drain and the memory is lost in the chips.
You are going to have to go to the BMW dealer and have them re-write your system, and it will cost you about a hundred bucks. They have the plug in device that will restore the system and it is not sold to the general public. That is why it is called ant-theft, so if someone steals your radio it quits working.
