As everyone has said, check eBay. There's a remote specifically for the 2000-2002 Accord; they're not interchangeable with other years/models. Look up seller "mykeyless" on eBay. His remotes sell for a good price and he gives you instructions on how to setup your remote.

Don't go to the dealer unless you're willing to pay a ton of money. I got my remote off eBay for $27.99 shipped. It's not a new remote but it's in good condition and works great.
