I have a '03 SE/SC all options (should have transponder key).

I went to Lowes, they couldn't make me a copy, they didn't have a match to the key, they don't stock it, the guy said its a transponder key thats why they don't carry them.

Called dealership, they said yes its a transponder key. I can't remember how much they wanted for a spare $50+

Went to Home Depot, they made me a cheap regular spare for $1. Tried it works.

No need to waste money on a transponder, that doesn't work, or isn't installed. Same BS from the dealership as usual.
