Anyone who is smart, what an original key of Peugeot and cost him this is too much for his old used lies right here. Price / performance ratio is absolutely in order. I had to stop even the "inner workings" of the housing Deburring something, but to do it does not require too much manual dexterity. The push buttons are stiffer than the original, so must be pressed firmly. But I think for the huge price difference, you can take the quiet in purchasing. The housing tends sometimes to jump to it, but on the other hand can with glue or heat of the frame to proceed. I left it because I probably soon have to replace the battery and then I probably no longer could use the housing. NOTE: There are also housing offered in China, although this one cost three euros more but was sent by a German dealer and thus did not make any problems at customs. That's me all worth it.
