From what’s been said, I’d guess you delete all keys from RFA and BCM (not sure of procedure). Then you’d program the key you have as the master key (in BCM key memory 1 or whatever it’s called and then into RFA).
krusing will be able to clarify exactly
and I agree with his reference dealer mission statement
"If you Can Not Dazzle Them With Brilliance, Baffle Them With Bull"
That is Correct,
Delete all the Existing Keys in the BCM and RFA, as the Procedure is in the BCM Menu, and includes the RFA unit.
[Well it is in the Autel Unit I use]
It has a Timer of 10 minutes to time out to start the Programming Feature.
With any Key you have on Hand, you need to program it as a Master [Key1],
Then It askes for a Second Key [Key 2] to be Programmed in.
[Hence the Reason you normally get 2 Keys]
It takes all of about 1/2 hour,
But,
If you lose the master Key, and wish add a new one,
The BCM askes for you to inset an existing Working Key [eg: Key 2] and it will go through the procedure and add the 3rd Key in the BCM,
Then you will need to add it in to the RFA.
This takes about 10 minutes.
