It sounds like your old one is shot, or miss-programmed. I bought a new one from Amazon for only $13.95 with battery installed (after locking my original one in it the first time I drove it to work- used to my Nissan keyless FOB that I never have to touch), and it worked great! Came with on-line instructions- the Vette (at least my '01) can be programmed by owner without a lot of difficulty. From world wide remotes- very happy with it. It is the exact one my car came with- only new (old one had worn out ICONS you could not see). Keep them separated by some distance, or it will de-program the other one (my original now does not work- but I will re-program it someday, I got a spare key, so no hurry).
