Perfect fit in a F22 M235. Very easy install. It took less than 60 seconds. The sticky gum method really does work vs pulling out the ignition switch! The sticky gum did not take any paint etc. off of the original BMW switch button. Buy it from this brand/seller as it comes with the sticky gum needed to pull out the old switch button. The product came with zero instructions. I just read the prior Ebay reviews and watched a couple of You Tube videos from Mark Mollat and Messay Garage.
