Review on Enhance Your BMW Key Experience: HelloAuto Key Replacement Button Pad & Smart Remote Cover for BMW 318i, 323i, 525i, 528i, 530i, 535i, 540i, 735i, 740i, 740iL, Z3 by Keith Aluguvelli

I have now ordered 3 or 4 of these replacement knobs for BMW E39 and Range Rover. Factory buttons on BMW keys suck. If you keep them in your bag, they can last about a year before wearing out. I love how easy it is to swap out these buttons and keep the buttons looking brand new. The exchange takes about 10 minutes and looks perfect. When removing old buttons, I strongly recommend taking your time and not partially removing the buttonholes.
