My wife bought a Peugeot 307. When master key with remote control was the complete spring mechanism in the bucket. My shop where we bought the car (Nissan) said: "If I fix you the key will cost a little more than a hundred euros" and rejected the key Repair from. But with Amazon you can get almost everything. Wanted, found, ordered !! I built in about 2 minutes to electronics - that's really as fast and fits properly. Only when changing the key bit there was something tricky. When the spring mechanism must be rumtüfteln something to see through to the changing tactics, but it worked. As in the heading: FITS TO Peugeot 307 - insofar buy recommendation !!
