My thought here is that Dealer key(s) would be sourced to the VIN, containing a chip code pre-coded within the EWS, a total of 10 codes. The tumbler assembly would also be VIN matched to the keys. Tumbler does not play a roles in key, EWS, ECU ‘conversation’, but the antenna ring located on the tumbler does.
