I have a flat tire and no wheel lock key for my M240i.
The Firestone near me cannot help unless they cut it.
The dealer is over an hour away. I didn’t think to check for this when I bought it.
The dealership hasn’t been super helpful.
I do not have run flats.
Don’t be like me.
Fwiw, the little card that comes with the wheel lock set (normally where the stock lug bolts end up) has the key # on it, it’s the last 2 digits of the serial number. Hope this helps someone, keep that card safe.
