First thing the two pieces don't match.  They are different colors.  Next the handle latch didn't extend.  Called the manufacturer and they informed me I had an older model.  They sent me a new latch of the proper color immediately, but when I was installing it, the pin broke on it!  Used my old latch which actually works.  Let the manufacturer know the two pieces aren't the same color (sent them a photo) and they in turn sent a new handle.  Wrong color again.  I give up!  The lock works great and I love it, but the experience was a fiasco that makes me regret it for the most part.
