Replacement Key

Hi Guys,

I just purchased a 1997 CL 3.0 for my son. It came with 3 keys (2 masters and 1 valet). I wanted to get another master key so I called my local dealership and they said it would be $26. I was a little blown away by that so I'm asking you guys if this is what they sell for.

Is there an online options that would be cheaper?

Thanks

Mark
