I will be micro-soldering a new chip onto a used key, making a copy of my current key and then flashing it onto the virgin chip.
The E9X came with three keys:
Early CA: KR55WK49143
Late CA: KR55WK49147
Non CA: KR55WK49127
I have a 06 330i with the early CA key. If anyone wants to donate their non working keys (any model) I will send you a shipping label. Send me a PM.
I have a programmer on its way from china:

The programmer will do everything except make a EEPROM DUMP. This is used to make a new key that will fill one the ten slots in the CAS module. I have not found a reasonably priced tool to perform this. Some people say you can use a raspberry pi to dump EEPROM.
Once I get the programmer, keys and chips I will post an update. They should be here in two weeks. If you have any incite beyond "Go to the dealer", that would be greatly appreciated.
Update 6/29:
I found out that non CA keys can be programmed to CA cars. I found the tool locksmiths use to program aftermarket keys, it is called the BMW Multi Tool. Is is $800 which is not worth it to a individual.
You do need a EEPROM dump so I bought the R270 and a Raspberry pi to see if I can get a dump. |
I think you can dump the EEPROM with Bus pirate for pi..
