The old rubber keys in my E39er radio key Been totally - I'll call it - "vermatscht". Who so also has a key, will know what I mean! In addition, the keys stuck already on your fingers, because the rubber began probably gradually dissolve. The ordered new keys feel much more comfortable now. The installation was straightforward. When removing the old rubber part, however, it was a bit expensive for my key, to completely remove the rubber residues from the plastic housing of the key because the rubber but strongly stuck to the plastic. With the blade of a screw puller but I could see the rubber residues completely scrape off the plastic and then use the new keys. previously I have abgechnitten the nipple for the LED with a cutter knife, because it is unnecessary when E39er key. The key now looks not as good as new, but much better than before - and most importantly, he now feels comfortable again on. Tip: best two rubber parts ordered (an addition for the spare key).
