Query: Keys are not wooden and not in tune

This is a cute toy, but the one I received has one key way out of tune. I got it for my young son because he loves music and I wanted him to be able to make his own, but teaching young ears with an out-of-tune instrument seems defeating. I will be exchanging this in hopes that it's just a problem with this particular one, since the other keys sound good.Also, this is not a xylophone (with wooden keys), it's a glockenspiel (with metal keys). When the manufacturer says "wooden," they only mean the frame.
