Does this product include the internal circuit board or battery?

No. This item is an aftermarket protective replacement outer casing and uncut mechanical key insert only. You will need to reuse the existing functional internal board, battery, and proximity transponder components from your old key.

Will I need to program this key casing to my vehicle?

No programming is necessary. Since you are transferring your original internal circuit board directly into the new shell, your BMW F Series vehicle will immediately read and recognize your key.

Is the emergency key blade included with this housing?

Yes, a brand new emergency mechanical key blade structure is included with the smart shell. It is highly recommended to take the unconfigured blade to an automotive locksmith to have it cut smoothly to match your door lock.
