From a TOAF developer!
VIN can change in LSM, BCU, SRS and probably can be done in the engine control modules. Between EWS, IKE, DDE / DME you can copy ZCS codes.
Used remote control you can add to the BCU by TOAF. You need a special code from the sticker which is located on the electronic board remote control.
To add a new or used transponder you have removed from the case EWS module. Then you are programming it on the table. New is a simple job. To add a used transponder, you must have a password with parent EWS module. All with separate utility - for example, "EWS EDITOR".
