Can't seem to add second key

Post by Mogzy » Sat Mar 03, 2018 2:08 pm


So I've attempted to add a second key to my 2004 Mazda rx8, the second key I'm trying to add is from my 2006 RX8 that I've had a blade recut for. I can re-add my original key no issues but it's refusing to let me add the second one, and as such I can't start the car as there are no longer 2 keys known by the ECU. Is there a work around?

one other thing, the key with my 2004 was the old style where the fob (4 button) is separate to the key, and the one I am trying to add is a 4 button flip key.


I posted this in the general support forum originally but thought it may be best here, cant seem to delete my original posting?

Have you tried programming the 2nd key first to see if that is successful?
