Bought to replace a plip 2005 307SW. If we completely replaces (thinking of the small magnet, not really visible), it works, just a little game at the metal part of the key. By cons, if you want to keep the original rear shell (like that found the Peugeot logo), it does not fit exactly ... it must be less than 2.1 mm on each side too, but enough so that it does not semboîte correctly. I managed to make it fit force and now the key works, but the new hull is slightly wider than the old one, so there is a rim around the key. Otherwise, it works flawlessly
