I lost mine and am now using the spare. Any advice on how to get 2009 Lexus GS replacement keys cheaply? Anybody tried the ones sold on e bay? Do they really work?

Thanks

 

I tried one off of ebay and it did not work, but I know somebody else who got one that did. We purchased from different sellers, so I don't know if it has to do with the seller, the key, or luck of the draw. Both vehicles were 07 GS. I got one new from dealer and had locksmith program it with no problem whatsoever.
