I have a 307 Peugeot car and the car key 2 button blip had become damaged so I ordered a case replacement on ebay. I took the older casing off and replaced with new casing and found that the locking/unlocking worked OK. When I tried the key to start the car it would turn the starter motor over but would not fire the engine. After trying to understand why it would not fire the engine I then replaced half of the casing which had the Peugeot Lion on with the new 2 button casing and everything then worked ok, but I cannot understand why?

That part of the key contains the transponder chip - that the car computer system recognises and allows the car to start. Its a passive component, needs no battery or maintenance.

Aha that'll teach me to read the post correctly
Maybe the metal bits of the fob are acting like some sort of antenna?

You are quite right about the transponder I have found this:
"Second, there is a coded electronic tranpsonder chip; This is usually embedded into the plastic part of your car key. Many drivers wrongly think that their car key doesn't have this feature just because there are no buttons or remote central locking on their car key. But this is a mistake, virtually all modern car keys have transponder chips inside."
There must be a transponder chip embedded as it says above in the "old" plastic part .
Many thanks

Take the original key case to a good locksmith that does car keys and they can decode the original transponder and program the new one.
If you only have the one key then this is a good idea as they can also tell you what the code is for future use. Otherwise if original transponder fails it will be a case of more money to recover the code.

er just dont tell the insurance company about it.

beaware that a lot will just clone the key.so you may end up having 2 working keys,but you still will not be able to reprogram them yourself.
