Thought I will post a result of key mod into separate topic as there have been some questions and pictures about it in different topics. In this video you can see how to open key cover - thanks to terryt for the link. In real it was quite hard to open the cover only with fingers, screwdriver made it easier. After the key was opened I removed standard plastic cap and replaced it with chrome cap. You will need torx T6, which is probably the smallest available. Next step was installation of FR key cover and here are some photos of the procedure and result: FR cover is just glued over the standard key, so if you want to have chrome cap, you have to install it first and then glue FR cover.
