Following the purchase of 207 used, I had to replace the shell of my only key because it was in very poor condition. So I ordered this product without paying attention to the comments and I did well. I do not agree with the other reviews, I found the product ends up rather well, all locations are now (for the battery and the circuit). After some difficulties to turn the key, everything is perfect. I even got a little Peugeot sticker. Only small problem: the delivery time (2-3 weeks)
