Hello and welcome to both you and Smokey.
You're spot on - it is stressful being shoved in a box and experiencing a car ride to a completely different environment, so what you need to do is settle him into his cage in a nice quiet area and leave him be for at least two days. I know how difficult it is but you don't want him to associate you with something bad, so have patience.
What kind of hamster is he? That will help people give you some species specific advice.
However, take a look at the wiki pages, they're really useful and give lots of handy tips on taming, etc. You have two days to get your reading in!
Getting it right now will make it a much smoother process.
Let us know what size cage/wheel etc you're using as well, as getting all these things correct will make Smokey much happier.
Congratulations!
Lydia and Artie.
