How do you program mulitple transponder keys
 

Greetings.

I have a 2007 Mazda 5 and programmed a 3rd key using the directions in this forum. I now have 3 programmed transponder keys and have a question on how to program a fourth.

1. Is the order: good1, good2, blank1?

or

2. Is the order: good1, good2, good3, blank1?

The directions say to repeat the directions for each additional key, but, it doesn't say if it is 2 plus the blank, or is it ALL the programmed keys plus the blank.

I hope I worded this clearly, thanks.

You should only need any two of the three key's to program the fourth. So... it's
good1, good2, blank1
or
good1, good3, blank1
or
good2, good3, blank1

Thanks for the reply. I have heard different things about programming multiple keys. For the amount of "hits" this question received, I thought it would be more popular.
