Key and remote stolen

[GseaQ]

Hi all,

I dropped my keys without realizing it a last week. I know where I dropped them, but they're gone. Somebody picked them up and kept them.

I'm getting a new key cut and it and my other keys programmed. Is there a way to change the channel on my other remote and the car so the lost one will no longer unlock the car? I figure whoever got the keys will come back to the parking lot to see what car lights up when he pushes the buttons.

Thanks,
Glenn
