When you do the pairing procedure you need to do both keys at the same time.

I figured it out. Tried both keys at the same time. Didnt work. Decided to yry something else. Started the procedure for reprogramming, did one key and before ending i did the other key. Both working now. Guess if its open to programming you can do as many keys as you want.

thank you for the link, I had one FOB with a dad battery when I bought it this week. Changed battery and found this procedure in the link posted by thecos, and all is well... at least after I reread it and realized steps 1 and 2 are only performed for the first key, and then 3 and 4 ONLY for each additional key. Live and learn...
