If it weren't, then there would be no need for codes with new transmitters. The transponder pill does not come with the new key head and code, but must stay with the car or immobilizer that it is matched to.
Also, if the transmitters were interchangeable without a code, then anyone with a 986 key head could unlock your car. 
In other words, if the code were for the transponder and not needed for the transmitter circuit board, then why would the transmitter circuit board come with the code and not the transponder? |
PW, thanks for the correction! Apologies to the OP.
