Talking OBC Ignition Lockout code forgotten?

I am new here and thought I'd share something I recently learned with all of you.

I had my car parked in a parking lot and decided to set the ignition lockout code on the OBC. I guess I didn't really need to, but it is a toy that I've never had on another car!

Well, I came out to go for lunch and punched in the code, and I either mis-keyed the number when I put it in, or forgot what it was (I thought I knew it, but my memory isn't as good as it used to be), but the OBC wouldn't accept the code. I was stuck and couldn't get the car started.

The only thing I could think was that I'd have to tow the car to the BMW dealer and pay big bucks to have the code reset or something like that. I thought that I'd disconnect the battery and try to clear the code that way.

To make a long story a little less long, what you have to do is to disconnect the battery (I disconnected the negative and then the positive and shorted them together and then reconnected them). Then put the key in the run position and watch the OBC count down for 15 minutes. DO NOT turn the key off during this time, or the counter will restart at 15 minutes again. After the 15 minutes you will be able to start the car.

Anyway, I just thought I'd share this with you, as I'm sure if it happened to me, it could happen to you!

Don't worry, there is a much faster way to defeat the CODE function.

good point John

a friend of mine fitted a high-end model alarm a few weeks ago and challenged his cousin (convicted car thief) to bypass it and drive off....he did it in 86 seconds

gutted!

Well, JohnF, I have no doubt! I'm thinking that the code will help protect against the casual joy rider. Let's face it, if a real pro wants your car, it's his!

True enough, but I really wouldn't put too much faith in the CODE function. If you want to protect the car, I would retrofit BMW's EWS-II system (or something comparable) if the car doesn't have that already. Transponder EWS systems have been very effective in Germany and cut the auto theft rate to a quarter of what it was about ten years ago.

Lockout code forgotten

I don't think disconnecting the battery will do you much good. I don't think it did for me. I think what you have to do is turn the ignition on and let the counter count down. It was a long time ago, and that car is gone now. Got a 2007 e93 now!

Hope this helps!
