4 keys from new: 2 remote, 1 valet, 1 wallet key. So 6 key codes remain for spares.

Here some additional bedtime reading about EWS.

Thanks for the correction, and that is great info in the PDF.

It has very detailed info on all the evolving EWS versions. Hopefully I never have to read and understand all that for reasons other than being curious about it.
