ask them how much it costs to cut and program a transponder key if you bring in a blank. I sell them on my site for $15+shipping. The transponders work well. right now all I have are black head keys, hopefully soon I'll get clear head ones back too.
Anyhow, A lot of stealerships charge anywhere from $25-50 per key. Mine charges 29.99. Others sell the keys themselves for a more modest price of $15-$20. Usually the programming is the expensive part because a tech needs to sit there with a computer hooked up to your car for a whole hour (part of the security procedure to program new keys).
It's worth a shot though.
