I choose the brass key only. I found out earlier times that the fancy colored keys dont always work well. I was locked out of my apartment and had a colored duplicate. Could not get in......! Even the locksmith could not get in........ with the key. So service 5 stars ( easy to use the duplicate keys machine, quality keys 2 stars

I am changing my review. I originally posted a negative review because I thought I was shorted one key. I was not. But note that if you do the buy 2 and get one free, the free key might not be the one that you chose. For example, I chose the teal key and the 3rd copy was brass, same as the other order I chose, it took awhile for me to figure out that I was not shorted the one teal key. I hope that makes sense to the owner and to future customers.
