I agree to use a piece of your clothing or something with your scent on it inside the crate. Then, get him a SUPER treat that he ONLY gets when he goes in the crate. For Ozzy, that's the only time he gets the Kong stuffed with peanut butter and 2 cookie treats. Throw a couple of his toys in there. Ozzy's crate has a flap you can open on the top to put your hand in, so when he IS locked in I can still give him treats and pet him.

Give it time. It'll probably take a while for him to feel comfortable in it. My SIL calls her dog's crate her "bed". She's so happy in it she just has to say "go to bed" and she runs right in there and gets all calm and relaxed.
