I am trying to remember what the instruction for my car is ('91 525i), but
it involves disconnecting the battery for either 30 or 60 minutes. Check
your owners amnual.
I have inadvertantly set the wrong code in from what I thought I had. Now,
I was not in such an inconveinent location as you, but here is what I did:
[ Help ]
- Write the code you thought you put in on a piece of paper.
- Exchange the first number position with the preceding number, then the
following number in the code you thought you put in. Write these down.
- Do this for all four positions. (i.e. 3456 is your original code, then
the first set will be 2456, then 4456, 3356, 3556, 3446, 3466, 3455, 3457)
- Run through the sequence you have written down. Your horn will be
blaring for a while, but you should find the wayward digit.
- If this does not work then you might have transposed 2 numbers or have
2 code positions mis-set.
