I ordered two remotes and blank keys for my 2005 Chevy Trailblazer. Remotes are identical to original and easy programming info included. This vehicle takes plain old non-"chipped" keys, so I paid a couple bucks to have them cut locally.
BUT I also have a 2001 Mustang fixer-upper that has a "chipped" key. If you have only 1 key and want another "burned", you are going to have about a $75 additional cost to have it done.
$#*! at your car company, not a supplier that is selling you remotes and keys for a fraction of the cost of what a dealer would charge.
