Rubbish, went to get it cut and broke because of poor quality metal… avoid!

### ⭐⭐⭐⭐⭐ Buttons work fine
*by R***E on 23 July 2024*

I got this because I'm restoring an old e46 325ci. The people complaining about the buttons being stiff are silly. The buttons are STIFFER than the OEM key, but they're perfectly fictional and after a day of using it, I don't even think about it being stiffer.
