ATTENTION, changing the entire model of the hull 206, you can not start with this key! Inside the original hull Peugeot is a small security magnet, which allows the key to be recognized by the car, without him, this one will not start. Two options are available: -either if they are only the membranes of key buttons that are hs, keep part of the hull with the Peugeot logo in which it is the small magnet and only add the new part with membranes. Likely that the assembly of 2 resists a bit but I confirm it passes, then replace the new screw has done so. -Or You have changed the entire hull and so in this case, take care with a fairly rigid sewing needle, take off the small magnet (take time for laborious) and once made to transfer him to the new shell .
If you are kind of sudden, breathe and take your time because this can upset.
This partly explains why Peugeot bill 70euros a key change, instead off the magnet, they program a new one.
