Looking for a new key!

Hi,
I have just bought a Used 2006 Chevy Colbalt LS. It however only comes with 1 key. I am just wondering how much it would cost to get a new key and a new remote (used for the electric locks).
Thanks!

I bought keys online, then had them cut locally. As long as you have one key, you don't need the dealer to do this.

For example: https://www.ikeyless.com/vehicles/Chevrolet/Cobalt

How do you program the keyless entry?

the fob needs to be programmed with a scan tool
