Keys

Post by Kingibj »

Got myself a 2004 model, the main key does not start the engine but spare key does. I've got no verification code, just wondering why both keys from same car don't do the same job :(

Are they remote keys? If so, it is likely that the transponder in the duff key has been lost. It is a small black plastic rectangular part clipped into one of the plastic shells of the fob (not the remote module). Failing that, either the transponder is defective, or the BSI has "forgotten" that key. It can be re-taught by using Peugeot Planet diagnostic system, but you also need the four digit security code.

Some car locksmiths can clone your good key.

EDIT: If the transponder has been lost, the remote module is useless - you cannot just programme a new transponder - you must use a brand-new remote module as well. Just keep the key blade for the new fob.
