A Blank key must be available, used keys are not supported yet.
You must understand that not all CAS versions accept this method for remote keys, but all flat CAS versions (not encrypted versions) accept the transponder (PCF7936) to be programmed this way. So if you want to program a transponder, this is the right place where to do it.

There is some important note about programming transponders (PCF7936): BMW CAS uses Crypto mode, while default (factory) mode in PCF7936 is password mode , in this case user must change the transponder to crypto mode, this can be achieved by any key programming tool supports the Hitag 2 protocol, Autohex II software offers to change this mode using HTag Pro key programming tool as seen in below picture.

PCF7936 Must be in Crypto mode
