I have BMW 525 D E60, 2004, 177 hp. My father lost the first key and we're currently using the 2nd key. I bought a blank key from AliExpress and a local locksmith cut it - link here. We're able to lock/unlock the door manually, but nothing else, which is kinda expected, because I haven't programmed it.
I have Autel Maxicom MK808 which is able to add/remove remote keys. These are the steps I did but when I try to use the feature "Teach in an additional key", it says "An additional remote key functions immediately. No initialization is necessary.". What does that mean? I also tried to block key 1, which my father lost and replace it with the new one by following the procedures and using "Initialize a new remote key" at the end, but "The new remote key functions immediately. No initialization is necessary." appeared, so it's kinda the same.
Does someone know how to do it on that specific car?
