Lost my wheel lock key so I'm looking for a replacement. BMW X3 2011.
I borrowed neighbours X5 and 528i keys and they dont fit, theirs appears to be 16 spline while mine look like 21 spline.

i looked through

Been in your shoes a long time ago. The only way to fix this is to go to the dealership. They have a master kit for all possible OEM wheel locks. It's done by trial and error until you find the correct key. Now, if I were you, I would assist when they do it, because they are in a rush and and don't pay close attention to this (at least that was my experience). There are a few keys that are close, as in they might fit, but not 100%. And when you try to take off the wheel you realize that you can totally damage either the key or the bolt.
In my case there were 3 different keys that were very close, but only 1 was the right fit. All 3 passed in the bolt, and they sold me a wrong one the first time. After close inspection when I was back, you could see that correct one fits really snug. The other ones had a small play, but when the tech was in a rush and didn't really care, he was satisfied once they key fit in the bolt and he couldn't turn it by hand.

I’ve determined that it has to be one of Code 30,32,33,34,37. will need to count the teeth of my current bolt.
Code.........Spline teeth................Key Part Number
Code 30..........14.......................36 13 6 765 543
Code 32..........16.......................36 13 6 765 545
Code 33..........17.......................36 13 6 765 546
Code 34..........18.......................36 13 6 765 547
Code 37..........21.......................36 13 6 762 342

Could be. When I looked for my wheel lock, as I said, the dealer had the master lock kit. It's a like a small suitcase with many wheel locks. Way more than the few posted in your link. But who knows, maybe it will fit just by counting the splines

I'm sure you've done this already - but if you bought your car new you should have two keys. One will be in the trunk compartment and the other should be in your leather pouch with the owners manual.
