With respect to the chromed end , in place of the plastic end, as soon as my wife got her new Polo in 2015, I noticed that the end had changed to being plastic, so I ordered up a couple of genuine VW Group chromed ends, fitted one to my key, asked my wife for her key so that I could change it as well - and she asked me to let her see/feel my modified key - then said "no thanks, my handbag is heavy enough already" - and of course she is right, doing this chrome end mod does come at a price which is a significant weight increase! So that means that I have still got one chromed end available, just a minute, my older daughter has just collected her new Leon Cupra - I need to check out what she thinks about this as the comment " key very plain and cheap looking" came out after she test drove it, maybe now that she thinks that the SEAT
badge is slightly copperish she will have changed her mind as these cars are "black" anyway, except strangely, the exhaust tips!
