Replacement Key Fob

[Jempie]

I know this is an old thread so apologies for resurrecting this but as it displays in the top 2 results in google I thought it only right to correct this as people stumbling upon this would be misled. Blank E85 & E86 Z4's keys CAN be programmed. You will need a blank key with a virgin transponder & an EWS programming module such as the AK90+ (Others are available). Google on the internet and there are plenty of articles that explain how to do this. EWS programming modules are a lot cheaper than a new key from BMW but It does involve removing the EWS module from your car and is not without risk.

Thanks, I have just stumbled across this thread to get a replacement key, so thanks for updating!
